We were often told to live within our means and not to overspend. Living frugally makes a lot of sense as someone who makes $3,000 a month cannot afford a rent of $4,000. This concept is simple to understand in financial terms but when it comes to manufacturing, things get a little cloudy.

In th is i ssue o f Asia Paci f i c Metalworking Equipment News, we revisit the issue of sustainable manufacturing. It is a constantly evolving subject, where the definition of the term can take on many forms. In addition, there always seems to be more to add on to the concept as time goes by, be it a new research or simply new takes on the philosophy.

There is perhaps no good way to define sustainable manufacturing. Therefore, it is best to leave things as that because sustainability can mean different things to different people in different industries or countries.

What most people can agree on

is the perceived value of sustainable manufacturing, ie: how can we benefit from it? Whatever the motivations of pursuing sustainable manufacturing are (monetary or environmental), the prize for those who are successful in sustainable manufacturing are the ones who go home with both trophies.

At Asia Paci f ic Metalworkin g Equipment News, we adopt a more quantifiable approach in looking at this abstract issue, ie: by analysing sustainable manufacturing’s individual constituents. In this issue, we choose to look at remanufacturing, a concept that is perhaps not quite fully understood at this point in time.

As such, we hope to raise awareness on the difference between repair, reconditioning and remanufacturing. Although this is just a small part in unravelling the mystique of sustainable manufacturing, it is the all important first step.

APEC Growth To Gradually Accelerate: Analysis

Surabaya, Indonesia: Economic activity in many APEC member e conom ie s wa s adverse ly affected by heightened concerns about the Euro area’s sovereign debt issues and weaker trade last year. But growth in the region in general appears to be improving and is set to gradually accelerate which could provide a boost to the world economy.

The gross domestic product of APEC economies is forecast to rise 4.2 percent in 2013 and 4.7 percent in 2014. By contrast, growth in the region was unchanged year-on-year in 2012 at 4.1 percent, reveals a APEC Economic Trends Analysis.

APEC Trade ministers will meet under this backdrop in Surabaya, Indonesia. The analysis

East Hartford, US: Pratt & Whitney has partnered with the University of Connecticut to establish one of the most advanced additive manufacturing laboratories in the US, the Pratt & Whitney Additive Manufacturing Innovation Center.

This facility will be used to further additive manufacturing R&D. Additive manufacturing is the process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies. Materials are added, versus the traditional subtractive method such as computer numerical controlled machining, to precise geometries determined by CAD drawings.

Pratt & Whitney To Advance Additive Manufacturing Research

was produced by the APEC Policy Support Unit to help ministers gain a greater understanding of the broader economic environment in the region.

“There are ongoing concerns about the health of public finances and the banking system, especially in Europe, as well as price pressures on property and stock markets,” said Dr Hew who is the director of the APEC Policy Support Unit.

“ M o d e r a te d i n d u s t r i a l production, an increase in trade restrictive measures and the reduced availability of trade finance adversely affected global trade last year. By October 2012, the value of global exports barely grew from the level seen in 2011,” he added.

Wea kening t rade wa s a particular challenge for small, open APEC economies. Gross domestic product growth among them slowed to 1.7 percent in 2012, less than half of their rate of economic expansion in the previous year.

“Activity in some large APEC economie s rema ins below optimum levels but is steadily improving,” noted Dr Alan Bollard, executive director of the APEC Secretariat. “This, combined with the continued resilience of emerging economies in the region due to strong domestic demand and investment, is contributing to a more favourable growth outlook for the short to medium term.”

Global trade appears to be getting a lift from these developments. The volume of world imports increased 4.1 percent year-on-year in January 2013 which was the indicator’s s h a r p e s t i n c r e a s e s i n c e September 2011.

The report states that fine-tuning the pace and composition of fiscal adjustment packages, attention to capital flows and actions to strengthen financial markets and institutions are needed to keep APEC economies moving in the right direction. It also calls upon policymakers to support the channeling of capital inf lows towards productive infrastructure investment.

Said Paul Adams, Pratt & Whitney's chief operating officer: "Additive manufacturing is complementary to traditional methods by enabling new innovation in design, speed and affordability. It is necessary to build the next generation of jet engines. We are currently using additive manufacturing to build complex components with extreme precision for the flight-proven PurePower commercial jet engine."

The company invested more than US$4.5 million in the Pratt & Whitney Additive Manufacturing Center and over the next five years will invest more than US$3.5 million in the facility.

HSBC China Manufacturing PMI Shows Modest Improvement In Operating Conditions

Beijing, China: After adjusting for seasonal factors, the HSBC Purchasing Managers’ Index (PMI) — a composite indicator designed to provide a single-figure snapshot of operating conditions in the manufacturing economy — posted 51.6 in March, up from 50.4 in February, signalling a modest improvement. Operating conditions in the Chinese manufacturing sector have now improved for five consecutive months.

Production levels increased for the fifth month in a row in March. The rate of expansion accelerated from February to a solid pace, the second-fastest in two years. Behind the rise in output, total new orders rose solidly, and for the sixth month in a row. A number of respondents attributed growth to strengthened client demand. Meanwhile, new export orders also increased, albeit marginally.

Volumes of outstanding business declined for the second successive month in March. The rate of backlog depletion was broadly unchanged from February, and remained slight overall. Staffing levels, however, were relatively unchanged from the previous month.

Suppliers’ delivery times lengthened in March, following a slight improvement in February. That said, the rate at which vendor performance deteriorated was slight, with just over six percent of panellists recording longer lead times. A number of respondents linked the deterioration to increased orders placed at vendors.

Average input costs faced by manufacturers decreased, following a five-month period of inflation. However, the rate of reduction was marginal, with a number of respondents citing

lower raw material costs. Output charges set by manufacturers also declined in March, and for the first time since last November. The rate of discounting was modest, with approximately 10 percent of panellists lowering tariffs. A number of respondents attributed the fall to a combination of passing on lower input costs to clients and competitive market pressures.

Purchasing activity in the manufacturing sector rose for the sixth successive month. Growth quickened from February to a solid pace that was the third-strongest in two years. Meanwhile, stocks of purchases fell modestly for the second month in a row. Increased input buying and the depletion of stocks were both associated with increased production at plants.

Finally, inventories of finished goods increased for the first time in six months, albeit marginally. A number of respondents attributed the rise to increased production on the back of stronger client demand.

Commenting on the China Manufacturing PMI survey, Hongbin Qu, chief economist, China & Co-Head of Asian Economic Research at HSBC said: “China's recovery continues, mainly driven by the gradually improving domestic demand conditions. The decline in input prices suggests a modest pace of demand recovery and moderating inflationary pressures. This, plus the lingering external headwinds, implies the Beijing policy makers should keep a relative accommodative policy stance in place.”

Zurich, Switzerland: ABB has agreed to acquire Power-One. The transaction would position the company as a leading global supplier of solar inverters — the ‘intelligence’ behind a solar PV system — to a market forecasted by the International Energy Agency to grow by more than 10 percent per year until 2021. This rapid growth is being driven by rising energy demand, especially in emerging markets, rising electricity prices and declining costs.

ABB To Acquire Power-One Power-One has one of the market’s most comprehensive offerings of solar inverters, ranging from residential to utility applications, and a broad global manufacturing footprint. It also has a power solutions portfolio that is adjacent to ABB’s power conversion business.

The transaction is structured as a merger and is subject to the satisfaction of customary closing conditions, including approval of Power One's shareholders at a special meeting and receipt of customary regulatory approvals.

Steel Closes The Weight Gap On Aluminium

Brussels, Belgium: The latest in a continuing series of research studies suggests that steel auto body structures in the near future can be as light as today’s aluminium bodies, while meeting all crash performance standards and at comparable cost of current steel structures. The studies also address critical manufacturing challenges, showing that car makers can form and fabricate sophisticated steel designs, therefore accelerating implementation of this technology into production vehicles.

Adding to a weight reduction of 35 percent in its initial FutureSteelVehicle design, the steel industry’s most recent studies boost the mass savings to 39 percent, compared to a baseline steel body structure carrying an internal combustion engine, adjusted for a battery-electric powertrain and year 2020 regulatory requirements.

The optimised FSV body would weigh just 176.8 kg, putting steel on par with today’s aluminium production designs. An industry database of current production vehicles (A2mac1) shows these light-weight, Advanced High-Strength Steel (AHSS) body structures, designed to carry heavier electrified powertrains, fall in line with the lightest internal-combustion-engine aluminium vehicles, and are on par with other concepts featuring multi-material solutions.

The study results show that by incorporating FSV technology, car makers can avoid pursuing more costly alternatives involving competing materials and multi-material designs to achieve their goals.

“Our latest light-weighting projects show the continuing potential of steel and demonstrate how car makers can take advantage of steel’s design flexibility and use AHSS to meet their difficult challenges for improving fuel economy and reducing green-house gas emissions,” said Cees ten Broek, director, WorldAutoSteel, the automotive group of the World Steel Association.

The two most recent studies, called 'FSV Final Gauge Optimisation' and 'FSV Near-Term Front Longitudinal Rail Shape' streamlined the FSV design and devised alternative geometry (for the front rails), respectively. The former led to an additional mass reduction of 11.6 kg, compared to the initial FSV design, bringing the total weight savings to 39 percent. The latter validates two different, but comparable, front rail designs, expanding the range of solutions available to car makers in the near term.

Steel auto body structures in the near future can be as lightweight as today’s aluminium bodies

Global Experts Poll: Economic Confidence Up Significantly In Second QuarterGeneva, Switzerland: Confidence in the world economy has increased significantly over the past three months, according to experts polled by the World Economic Forum.

The Economic Confidence Index rose to 0.48 from 0.43 on a scale of 0 to 1 during the first three months of the year, amid an easing of the Eurozone crisis and belief that the world economy may have avoided a double-dip recession.

The score puts the index back in neutral territory for the first time since it fell into low-confidence territory in the third quarter of 2012; it marks a return to its most

“It looks as though the worst is over and experts are not too worried about a double-dip recession of the world economy,” said Martina Gmür, senior director of the Forum’s Global Agenda Council, of the poll of 304 global experts.

T h i r t y - o n e p e r c e n t o f respondents said they are either ‘confident’ or ‘very confident’ about the prospects for the global economy, compared to 23 percent in the first quarter.

The remaining respondents were almost equally split at about 34.5 percent on whether they are ‘neutral’ or ‘not confident or not at all confident’ compared with 34 percent and 43 percent the previous quarter, respectively. The indices tracking confidence in global governance and global cooperation made similar significant improvements over the past quarter.

ShapeGrabber SG Central Software lets users easily configure scan settings, speed and resolution for ShapeGrabber 3D laser scanners.

Quality control operators who use a ShapeGrabber automated 3D scanner perform an inspection simply by placing the part on the scanner turntable and clicking “Run”. The ShapeGrabber scanner automatically scans and rotates the part according to the scan specifications (for example, the density of the scan and the amount of rotation required). The scan can be conducted using default specifications or can be easily customized by the using a user-friendly interface.

This generates a “point cloud”—an exact representation of the entire surface area of the scanned part. This point cloud data file is easily imported into the inspection software included with the ShapeGrabber system (Geomagic® Qualify). This data can be quickly compared to a reference file, such as a CAD model or the scan of a known good part, or measurements can be extracted directly from the scan data.

An inspection report is then automatically generated—with visual and numerical data—and can be saved or printed. The report quantifies the deviation of the part’s actual shape from the specifications, using GD&T analysis, error maps, tabular measurement, cross-sectional analysis, and more.

Optical Gaging (S) Pte Ltd (OGS) offers OGP / QVI non-contact and multisensor metrology systems like OGP SmartScope, QVI SNAP & contour projectors.

Over the years, OGS has expanded its metrology solutions with new products such as SHAKE SHR 3D CT (X-Ray) Scanner for non-destructive inspection & measurement and Vici Vision Optical Measuring system for shaft & cylindrical parts inspection.

Memory, Foundry & LED Markets Drive Fab Spending In SEASingapore: Increased spending in NAND and flash by Micron, LEDs by Philips and Osram, and continued investments by Globalfoundries will create new opportunities for equipment and materials suppliers in Southeast Asia.

For the Southeast Asia region, capital equipment investment will see some pickup in the second half of 2013 followed by a strong recovery in 2014. Overall front-end fab equipment spending is expected to double next year from US$810 million in 2013 to US$1.62 billion in 2014. Foundry and Memory are the two major sectors that invest most in the region.

The Southeast Asia region’s capacity growth for front-end fabs shows two percent increase this year and an expectation of higher growth (eight percent) in 2014, exceeding overall global capacity growth of five percent according to the Semi World Fab Forecast. The growth will mainly be driven by the

memory sector, specifically from NAND flash capacity as Micron gears up for further expansion at its Singapore NAND flash facility next year plus ongoing capacity conversion from DRAM to NAND flash at Fab 7.

Singapore is emerging to become the third largest NAND flash manufacturing country in the world by the end of 2014. The conversion and the expansion projects wil l drive related semiconductor investment in the region in 2013 and 2014.

For the assembly and test sector, Southeast Asia has long been the focal point of the industry with a large installed capacity from both IDMs and OSATs. This position contributes to the region being the largest packaging materials consumption market in the world, representing a market size of US$6.6 billion in 2013 and US$6.8 billion in 2014. The region’s back-end equipment investment remains

significant with over US$1 billion spending each year throughout 2012 to 2014, accounting for about 17 percent of worldwide share according to Semi.

Aside from manufacturing capacity, Southeast Asia region is now extending its va lue proposition to IC design and R& D areas with more joint development projects between multi-national corporations and local institutes. Semi expects to see a more robust semiconductor ecosystem arise from the region as a result of these endeavors and as companies seek ready access to customers throughout Asia-Pacific and South Asia.

Currently, Singapore has 14 wafer fabrication plants, including the world’s top three wafer foundries. The country also has 20 semiconductor assembly and test operations, including three of the world’s top six outsourced assembly and test companies. There are about 40 IC design centres, which comprise nine of the world’s ‘top 10’ fabless IC design companies.

Machine Tool Orders Suffered Negative Q1 In ItalyItaly: For the first quarter of 2013, the machine tool order index, processed by the Studies D epa r t ment o f UCIMU-Sistemi Per Produrre, showed a 9 . 8 p e r c e n t decrease against the same period of the previous year. In particular, the domestic order index showed a 35.9 percent decrease

compared with the first quarter of 2012.As far as exports are concerned, the index of orders

showed a 4.6 percent decrease, a downward trend that has now continued for four consecutive quarters.

Luigi Galdabini, president of UCIMU-Sistemi Per Produrre, said: “These latest results clearly demonstrate that the loss of competitiveness that the

political situation is forcing on the whole country is having a strong impact on the industrial sector.

The halt in machine tool investments, indicates a progressive and unavoidable loss of competitiveness of the whole country. Without the acquisition and the replacement of production machinery, user sectors will be unable to face the challenge of foreign competitors, whose investments in advanced technologies, although slightly slower than normal, will enable them in the short term to align themselves to us as far as production capacity and quality are concerned.” He added the contraction in manufacturing is directly linked with the decrease of domestic consumption and the failure to update existing equipment. There are however some positives in the export area.

“Until now, we have seen that exports have been able to hold their own, thanks to a well thought strategy, but also to the organisational and financial ‘sacrifices’ of our small and medium companies, which do not receive any public support. However, the survival of the enterprises cannot rely infinitely on exports,” he added.

Strong Domestic Demand Drives Growth In East Asia PacificSingapore: Driven by strong domestic demand, economies of developing East Asia and Pacific continue to be an engine of global growth, growing at 7.5 percent in 2012 — higher than any other region in the world, says the World Bank in its latest analysis of the regional economy. As the global economy recovers, the report projects that regional growth will rise moderately to 7.8 percent in 2013 and ease to 7.6 percent in 2014.

“The East Asia and Pacific region contributed around 40 percent of global growth in 2012, and the global economy continues to rely on the region’s growth, with investor confidence surging and financial markets remaining solid,” said World Bank East Asia and Pacific VP Axel van Trotsenburg. “Now is the time for countries to focus on helping the remaining poor, with more and better quality investments to

accelerate inclusive growth.”Fiscal and monetary policies

to boost consumption and investment helped susta in growth in 2012 across the region, with middle-income countries performing particularly well. Developing economies excluding China grew 6.2 percent in 2012, up from 4.5 percent in 2011.

In China, growth slowed to 7.8 percent in 2012 due to rebalancing efforts, while real disposable income of urban households r o s e b y m o r e t h a n n i n e percent, supporting household consumption, which contributed 4.4 percentage points to GDP growth.

Singapore To Improve Energy Efficiency Of The Industry Sector

Singapore: In an effort to improve Singapore’s energy efficiency and competitiveness, the National Environment Agency (NEA) has introduced mandatory energy management requirements for large energy users in the industry sector. These requirements will come into effect under the Energy Conservation Act (ECA).

The industry sector accounts for more than half of Singapore’s energy demand. In particular, the large energy users in this sector can play a major role in

the national efforts to make Singapore more energy efficient.

The large energy users affected are those with business activities that consume more than 54 terajoules of energy annually in at least two of the three preceding years and whose business activities are attributable to manufacturing and manufacturing-related services; supply of electricity, gas, steam, compressed air, and chilled water for air-conditioning; or water supply and sewage and waste management.

From April 22, 2013, these companies are required to register themselves with NEA and appoint one or more energy managers to monitor and manage their energy consumption. The companies are also required to report their energy consumption and provide information on processes resulting in greenhouse gas emissions, and submit energy efficiency improvement plans annually beginning in 2014.

These requirements affect some 170 companies which operate around 200 large energy consuming premises. To ensure the feasibility and practicability of the detailed requirements, NEA has conducted one-to-one industry consultations and briefings for these companies since the beginning of last year.

expansion of 2.4 percent in 2013 and a gradual strengthening to three percent in 2014. While still fragile, there are signs of a turnaround in real activity in high income economies. As such, external demand for the East Asia and Pacific region’s exports will stabilise this year. The most recent numbers on industrial production and producer’s expectations confirm continued solid growth.

Movements in high-income country currencies, such as the yen, are likely to affect trade and investment flows in the region in the short term. Some countries, notably suppliers of parts to Japanese industry and countries with considerable Japanese investment could gain, whereas countries that compete directly with Japan in third markets may face some headwind in the short run.

Siemens Recognised By General Motors As Supplier Of The Year For 2012Germany: General Motors recognised Siemens’ Product Lifecycle Management (PLM) software business unit as one of its best global automotive suppliers during its 21st annual Supplier of the Year awards ceremony.

“The honour of receiving the GM Supplier of the Year award with such consistency is a tribute to our team’s dedication to customer success, and a direct result of our two companies’ close working relationship,” said Chuck Grindstaff, CEO and president, Siemens PLM Software. “We are proud of our partnership with General Motors and look forward to the future as our software technology continues to help GM design, build, and sell the world’s best vehicles.”

The company was one of 83 suppliers recognised by GM who have consistently exceeded their expectations. This is the fifth time the company has received the Supplier of the Year award, and the third time in the last four years.

The award is given to less than one percent of GM’s approximately 18,500 suppliers around the world. The award is chosen by a global team of GM purchasing, engineering, quality, manufacturing and logistics executives.

Bombardier Transportation To Supply Trains To New Delhi

New Delhi, India: Bombardier Transportation has won an order from Delhi Metro Rail Corporation (DMRC) to deliver the Cityflo 350 mass transit solution for the upcoming extensions to Delhi Metro’s Line five and Line six. The extensions are part of Phase III of Delhi’s metro expansion plan.

Increasing the reach of the two lines which are already operating with the Bombardier Automatic Train Protection (ATP) technology, the new sections will further improve passenger transportation options in this city. The contract is valued at approximately US$47 million.

The extensions will add almost 35 km of double track and 23 stations to the existing 39 km in operation and are due to be completed in 2016. Bombardier’s project scope includes the design, manufacture and commissioning of the integrated train control and signalling system, including control centres, trackside and onboard equipment.

return to sustained growth in Japan would benefit the region as a whole.

A s the g loba l economy recovers, an emerging issue is the risk of overheating in some of the larger economies. The latest numbers suggest that, if global demand continues to revive, some major economies may reach the limits of their current production capacity, as the output gap has closed in those countries.

“Most countries in developing East Asia are well prepared to absorb external shocks, but continued demand-boosting measures may now be counterproductive, as it could add to inflationary pressures,” said World Bank East Asia and Pacific chief economist Bert Hofman. “A strong rebound in capital inflows to the region induced by protracted rounds of quantitative easing in the US, EU and Japan, may amplify credit and asset price risks.”

In East Asia and the Pacific, overall economic management has been effective in dealing with the global economic crisis, which has enabled the region to remain resilient and sustain growth.

The challenge for policy makers now is to build on these strengths and address short and long term challenges with smart policies:

Policymakers need to continue to be vigilant to react to shocks in the world economy, but be prepared to withdraw stimulus as the world economy recovers. For countries that show some signs of inflationary pressures, it would be a good time to rebuild policy buffers.

Several countries need to manage strong capital inflows by maintaining an appropriate macro policy mix, sufficient flexibility in the exchange rate and macro-prudential policies.

Most countries could increase productive capacity by investing in infrastructure and human capital, paving the way for continued high and equitable growth.

Amadeus: Asia Is The Largest, Fastest-Growing & Most Competitive Market For Air Travel

Madrid, Spain: An analysis from Amadeus Air Traffic Travel Intelligence solution reveals that worldwide air traffic volume grew five percent between 2011 and 2012, with Asia being the largest, fastest-growing and most competitive market for air travel. The analysis shows that Asia experienced year over year growth of nine percent between 2011 and 2012, followed by Latin America, at six percent.

Among other key findings, the study reveals Asia as the market with the highest airline competition. Seventy-five percent of the region’s air traffic is operated by three or more airlines and 27 percent by five or more airlines, making this a region with a very intense competition in all its air travel routes. This contrasts sharply with other regions such as the Middle East and Europe where just half of all air traffic on its routes is operated by three or more airlines.1

The analysis also shows that 22 percent of all global air travel is concentrated on just 300 origin and destination ‘super routes2’, each of which carries over 1 million passengers annually. Furthermore, 69 percent of all global air travel is made on major routes with 100,000 annual passengers.

In terms of connecting air traffic, the analysis shows the Middle East as a strong performer, with the three key airports of Doha, Abu Dhabi and Dubai all showing high connecting traffic volumes.

For instance, when taken as a group the three airports now serve roughly 15 percent of all air traffic volume that goes from Asia to Europe and from Europe to the South West Pacific. Furthermore, Europe-Asia traffic routed via the Middle East is growing at roughly 20 percent per annum.

Note1. For the purposes of this analysis an airline is considered to be ‘a competitor’ if its

market share exceeds five percent for the given traffic being analysed. Therefore if a booking is made and there are four competing carriers vying for the booking, but one has a market share <five percent we would view this as effectively three airlines competing for the business.

2. A route is defined as an Origin and Destination (O&D), that is, an absolute route between point A and point B. Passengers may have connected and flown multiple segments in order to reach their final destination but this is not the point in an O&D analysis. We are interested in travel between an origin and a final destination.

HCIL announced an investment of Rs 2500 crore (US$461 million) in its Tapukara plant in Distt. Alwar, Rajasthan to build an assembly line for cars with an annual installed capacity of 120,000 units, a diesel engine component production line and a forging plant.

W i t h t h e o b j e c t i v e o f strengthening and providing products which exceed diverse customer expectation with more speed, the company changed its global organisation structure from April 1, 2013 and has

appointed Yoshiyuki Matsumoto, managing officer, Honda Motor Company as ‘Representative of Development, Purchasing and Production in Asia & Oceania Region’ who wil l be based in India to control all Asia & Oceania Region.

The assembly line and forging plant is scheduled to be ready within 2014. Combined with the capacity of the new plant, the company's total installed production capacity will be increased to 240,000 units/ annum in 2014.

Nextant Aerospace Identifies Potential For Jet Market In AsiaShanghai, China: Nex tant Aerospace (Nextant), maker of the Nextant 400XT, the world’s only remanufactured business jet, believes Asia has the potential to drive sales in the global, entry-level business jet market over the next decade due to its rapid economic growth and increasing population of high net worth individuals.

The entry-level business jet market in Asia has grown rapidly over the last decade with the five years to 2012 seeing a 74 percent increase in deliveries on the previous five-year period (2003 - 2007). Globally, deliveries of business jets grew by just six percent between the same two periods.

In spite of this recent growth, the business aviation market in A sia remains relat ively underdeveloped compared to the rest of the world and is likely to continue to grow as its economies and high net worth populations continue to expand. It is for these reasons that Asia has been identified as a core part of the company’s expansion strategy.

The company estimates that there is currently one business jet for every 121 individuals with net assets of at least US$30 million in Asia, compared to one for every eight in the USA and Latin America. In Europe, which has the

Ever since the invention of the first cemented tungsten carbide inserts in 1927, companies in

the field of metal cutting have

Adding cleverly designed mechanisms and features around the insert and its holder can go a long way in helping it keep pace with the advancements in machine tool technology. Contributed by Hadas Zeira, manager of marketing communications, Iscar

Inserting IntelligenceInto Metal Cutting

endeavoured to reinvent their use by creating innovative geometries and chipformer designs. These engineering efforts are complemented with

advanced material sciences where substrates are constantly improved and being developed to enable machining under harder and tougher conditions.

T he endle ss pu rsu it to optimise machining processes coincides with technological adva ncements in machine tools , which enable much faster machining. The modern m a c h i n i n g c e n t r e s h a v e raised the bar for cutting tool manufacturers. They now have to produce highly advanced tool and insert geometries to sustain fast metal removal.

In addition, the price of carbide is rapidly increasing on a global scale, which placed pressure on manufacturers to be cost-conscious with respect to the products which they develop.

The two factors mentioned above have resulted in the pro du c t io n o f i n nov at i ve p r o d u c t s . T h e y e x t e n d the benef its of machin ing practices to a wider spectrum of applications. For the most part, they enable higher feed rates, yet reduce cutting forces and conserve cutting lubricant, making them suited for today’s high-feed, light-frame machines.

Holding FirmA s inser ts a re removable , h o l d i n g t h e m i n p l a c e automatically becomes one of the main factors dictating t h e p e r f o r m a n c e o f t h e whole cutting operation. It is therefore hardly surprising that many insert manufacturers are now putting in considerable re s o u rce s i n t he a re a o f clamping.

In the market today, there is a clamping mechanism that can hold double-sided inserts featuring double negative prism flanks. The dovetailed pocket and insert prismatic f lanks prevent the insert from being li f ted by the cutting forces

resulting in the double-sided dove ta iled prismatic f lank inserts being held in place.

Previously, cutting forces tend to cause the insert to tilt in lever clamp tools, whereas i n t h i s c la mpi n g met ho d , the phenomenon has been eliminated. With this clamping mechanism, turning at higher feed rates with a heavier chip load is available to today’s new turning centres. (Figures 1 & 2)

Think Small For Larger Savings For small -scale turning and grooving, wastage occurs when people use larger inserts than are actually required for a particular set of machining parameters. A way to eliminate this waste is actually quite simple, ie: use smaller inserts.

These smaller or Eco inserts do the same job as their larger counterparts but use less of the costly carbide. One example in the market today is the Iscar Isoturn Eco inserts. They are smaller than standard inserts

in that family, but match them for throughput while using less carbide. It is said that the Eco inserts deliver the same machining rates as their larger counterparts, and feature the same helical-edge, high-rake geometries for lower cutting forces (Figure 3).

License To SpeedWhen machining large parts, the issue of material removal often has an element of speed attached to it. Although fast and efficient material removal is important in all machining processes, the speed factor is arguably more crucial here.

CuttingEdgE


To speed up machining of large parts, typically found in power generation, transportation and heavy industry, the Iscar Heavy Superturn Lomx 402224 -H6P insert delivers secure processing and tool life even under unstable conditions.

Capable of a 35 mm depth of cut and a 2 mm/rev feed rate, the tool features a rigid lever lock insert clamping system and uses the tough grade IC8250 inserts. This insert is a suitable solution for large scale turning, which requires high feed performance (Figure 4).

The tangential orientation extends tool life by presenting the insert’s strongest cross section to the largest cutting force vector so the forces are mainly compressive. High-rake top face geometry, helical cutting edge and the chipbreaker on the insert create a gentler cleaving action, smoother chip exit and cooler running.

Heavy Duty GroovingThe issue of keeping inserts in position during machining is also important in the grooving segment. As such, there are new technologies designed for this purpose.

For deep heavy wide grooving inser t s , a f ronta l lock ing mechanism is now available on the Dove IQ Grip to do the job. The inserts feature a rigid dovetail clamping geometry and a locking mechanism with frontal access. It takes a half-turn to clamp/unclamp the insert.

touching on the area of surface finishing. Also an important co n s ide ra t io n du r i n g t he designing stage of an insert, new inserts, particularly those deployed in chatter- prone applications are formulated to improve surface finish.

A case in point here is the Heli2000 Chatterfree insert designed to improve surface finish in applications such as long-reach milling. It features an asymmetric design to suppress harmonic vibrations as well as the familiar wiper edge to improve surface finish and ground cutting edges for better perpendicularity (Figure 5).

Indexable inserts today offer a capable concept for increasing productivity and profitability when machining all types of materials. The inserts’ clamping geometries, available in a wide range, assure accurate cutting angles, good chip control, good surface quality, stability, and the possibility for machining all types of materials by use of the latest substrate materials.

APMEN: Please explain how biocides and amines can influence fluid longevity?Patrick Brutto (PB): Registered b i o c i d e s i n c r e a s e f l u i d longevity by keeping growth of bacterial and fungal organisms in check. Without biocides, these organisms will eventually degrade many of the typical components present in the fluids causing performance to suffer.

Amines can influence fluid longevity in a couple of ways. F i rs t , t hey he lp ma inta in optimum pH, enabling the fluid to retain its original performance characteristics for a longer period of time. Second, certain amines can improve the way registered biocides perform. This is especially important today, when some of the most widely used biocides are being de-selected due to customer or regional preferences, and/or regulatory requirements. This is the case for hexahydro-1,3,5 -tris-(2-hydroxyethyl)-s-triazine and other formaldehyde condensate biocides.

Amines which enhance the performance of the remaining registered biocides can play a significant role in maintaining overall fluid performance including

corrosion and pH control. An example is Corrguard EXT from The Dow Chemical Company (active ingredient 3-amino-4-octanol) which enhances the performance of a wide range of registered biocides.

APMEN: It is said that different geographical influences such as water quality, air humidity and temperature can affect the performance of a metalworking fluid. Do you agree with this statement and why?PB: Water quality has a large effect on the performance and longevity of water-dilutable metalworking fluids. In addition, minerals and anions dissolved in the water can greatly affect metalworking fluid systems.

Ca lcium and magnesium cations are often present, which will react with anionic fluid components (fatty acid salts, petroleum sulfonates, etc.), causing loss of emulsion stability and corrosion control.

Anions such as chloride, fluoride, sulfate and carbonate are of ten present and can influence the corrosivity of the water. Soft, deionised or Reverse Osmosis (RO) water will usually have a positive impact on fluid

performance and longevity, with one major exception: foam development and stability are often more problematic.

Water hardness (calcium, magnesium, etc.), usually reduces foam development and stability in part due to formation of water insoluble salts. Softening of the water, which replaces calcium a nd ma g ne sium ions w ith sodium ions, or deionisation/RO treatment which removes almost all ions, enables anionic fluid components to work more efficiently. Unfortunately, this can also result in foaming. Another strategy for dealing with hard water is to use non-ionic fluid components. However in some cases, these materials also cause foam development.

H u m i d i t y d o e s n o t have a large impact on fluid performance. However, it can affect the corrosion control of ferrous metals present in machinery and parts. The higher the humidity, the faster the machines and parts will corrode. As temperature increases, the rate of corrosion increases, but higher temperatures also accelerate drying which can potentially offset the higher rate of corrosion.

APMEN: Different metalworking fluids should be used for different materials, machine types and cutting tools. In other words, there is no ‘one size fits all’ approach while selecting a suitable metalworking fluid. Are there any data or studies that can substantiate this claim?PB : T he re a re nu m e ro u s technical papers and handbooks, such as those published by the Society of Tribologists and Lubrication Engineers, which discuss the impact of fluid types and components on the various metal forming and metal removal processes.

There is a trend to design fluids for multiple operations a nd meta ls. However, th is is only possible to a certain d e g r e e . L u b r i c a t i o n a n d cool ing requirements var y considerably, and one fluid type cannot possibly meet all the requirements of the wide range of operations and alloys.

APMEN: What makes a high performance metalworking fluid?PB: This is a difficult question to a n s we r b e c a u s e ‘h i g h performance’ is a general term. Different fluid producers and end users will define it differently. My definition of high performance is a f luid which meets the requirements of demanding operations, where ‘standard’ fluids cannot do the job.

T h i s c o u l d i n c l u d e applications where difficult alloys (titanium, magnesium, etc.) or part geometries are produced, or where water quality is poor. Another example is long-life fluids, where the end user expects little or no maintenance even in cases where tramp oil and microbial contamination are significant.

friction involved in working the piece. While dry machining exists, most other alternatives involve the use of a cutting fluid, which serves to mitigate the high temperatures induced during the machining process.

M e a nwh i le , i n l i g ht o f technological advancements that have enabled faster production, greater loads have driven the need to hasten the cooling process as well. As limitations exist in conventional liquids, a faster alternative can be found in nanofluids.

Coolants serve two main purposes in manufacturing — to cool and lubricate. While the first removes heat, the second reduces heat generation. Typically in the

form of oil, water or emulsions, these fluids play a pivotal role in multiple machining processes by transferring heat away.

It is especially important as excessively high temperatures have the ability to temper with the structure and surface integrity of the work piece, as well as tool life among others. As compared to conventional cutting fluids, nanofluids are more efficacious in the cooling process and are able to provide much faster results as well.

Thermal ConductivityConceptualised within the past decade, nanofluids are a relatively new development that can be utilised in various applications across industries that include biomedical, oil and gas and manufacturing. It comprises a mixture of nanoparticles (ie:

aluminium oxide, copper, copper oxide, gold, silver, silica) less than 100 nanometres in size, which are suspended in base fluids such as water, oil, acetone, decene, ethylene glycol and other biofluids.

The mixture has greater heat transfer properties as compared to liquid alone, because it includes solids in the form of nanoparticles, which naturally have better thermal conductivity. For instance, a study found that the addition of copper nanoparticles (less than one percent of total mixture volume) into ethylene glycol increased thermal conductivity of the base fluid from 40 percent to 150 percent.

I n f a c t , n a n o f l u i d s ’ superiority over conventional liquids can be summed up with three main characteristics: t h e r m a l c o n d u c t i v i t y , wettability, and viscosity.

Thermal conductivity is very much dependent on particle size, its temperature, or particle shape. Different types of particles and base fluids have varying levels of thermal conductivity, and researchers have found it to be enhanced with increasing particle volume.

The sensitivity of the mixture is also discovered to be greater for particles made from materials with higher conductivity and base fluids with lower conductivity. This sensitivity is generally more pronounced in nanofluids than base fluids alone.

Ac id i t y, a nd e lon gate d particles as opposed to spherical ones, also have a positive effect on thermal conductivity. The same was observed when additives such as surfactants were included in the mixture to prevent the agglomeration of particles into larger ones.

Wettability & ViscosityThe cooling effects of nanofluids are a lso moderated by its

Coolants play an enormous role in manufacturing by facilitating heat dissipation. With increased production loads however, manufacturers are looking for a solution to hasten the cooling process, which could potentially be found in nanofluids. By Sherlyne Yong

wettability and viscosity. It is generally more effective as it has a greater wetting area per volume, and adheres to the contact area more than conventional cutting fluids. Therefore, its enhanced lubrication and heat removal properties are also a result of being able to cover more surface area with the same, or lesser, amount of coolant.

Supporting this is a study conducted at the Indian Institute of Technology, where researchers found nanofluids containing one percent volume of aluminium oxide to have greater wettability when compared with water and a conventional cutting fluid. In addition, wettability can be further improved with nanoparticles that are near the liquid-solid surface.

Viscosity is directly related to heat removal as well, and is characterised by the level of fluidity. The greater the ratio of nanoparticles to base liquid, the less fluid it will be. Greater viscosity on the other hand, is beneficial for heat transfer as it enables the adherence of nanofluids to contact surface for a longer period of time. Nanofluids can easily be 50 percent more viscous than water. At the same time, most mixtures contain less than five percent of nanoparticles, as too much viscosity could lead to issues such as pumping inefficiency.

Use In MachiningNanof luids hold part icular promise in manufacturing, as it has the ability to enhance cooling action and can be utilised for improving various machining processes. This includes milling, drilling, and notably so for grinding and turning.

As compared to other systems, grinding requires more energy for every unit volume of material removed. Most of this energy is translated into heat that is dissipated at the contact area, which in turn has the potential to

cause thermal damage to the work piece. Not only will this affect quality, production rates will be slowed as well.

On the other hand, nanofluids can be used to moderate the existing situation. For instance, it is suited for cooling in creep feed grinding and lubrication in shallow cut grinding. For the latter, this can be achieved through Minimum

Quantity Lubrication (MQL). Likewise, these fluids improve

turning operations by providing better lubrication, which helps to alter friction at low speeds. This can be attributed to the flattened or exfoliated nanoparticles. At high cutting speeds, it helps to ease flow, while at low to intermediate cutting speeds, it can penetrate contact surfaces

and areas where chipping occurs. On a more fundamental level,

nanofluids are useful for raising Critical Heat Flux (CHF), and are reportedly up to three times more effective in doing so than water and oils. This stands true even for the mere addition of less than 0.1 percent volume of particles into the base fluid. A higher CHF is desirable as it slows down thermal damage by encouraging heat dissipation at higher temperatures.

Technical BenefitsTool upkeep is a perennial issue in metalworking as tools are often subjected to high temperatures in most processes. Prolonged exposure to heat leads to structural changes in the tool, as it turns soft and becomes more prone to damage. Likewise, this is extended to the work piece, where both structural integrity and surface smoothness are implicated.

Prolong ing a tool’s l i fe inadvertently leads to cost

savings as it eliminates the need to manufacture a new one. Chipping or fractures in the tool are commonplace and accelerated with high cutting wear and stress at the tool edge. In dry machining for instance, tool wear occurs most as thermal changes result in a greater vulnerability to deformation.

However, nanofluids serve to retard this process by providing more lubrication. As a result, tool hardness is retained for a longer period and wear is confined to the cutting edge in minimal amounts.

Meanwhile, surface smoothness is another favoured attribute as rough surfaces wear faster and are more prone to corrosion. In manufacturing, surface roughness is also difficult and expensive to control, and occurs most severely in dry machining as the tool edge wears more quickly. Presence of the cutting fluids serves to protect the cutting edge, resulting in a smoother machining process and surface.

On the other hand, nanofluids greatly improve the wetting properties of rake and flank regions of the tool, which enables better heat dissipation and the retaining of tool hardness. Relative to dry machining or processes using conventional fluid, surface roughness is minimal when machining with nanofluids.

Sustainable ManufacturingIn light of climate change and limited resources, manufacturers have been integrating sustainable practices into their production cycle where possible. The use of nanofluids has been touted as an environmentally friendlier alternative to conventional fluids at process level.

Due to its higher efficacy, less fluid is required to achieve the same cooling effects and this allows a reduction in conventional fluid consumption. With less effort required for waste management, one’s environmental impact is diminished as well. This holds

relevance as there is a greater focus on environmental liability and stricter regulations in place for waste disposal practices.

Apart from influencing one’s environmental footprint, the adoption of nanofluids may lead to cost savings as well. Most fluids account for 7 to 17 percent of the total machining costs, which will naturally go down with lessened fluid consumption. Not to mention, waste handling has become increasingly complex and expensive as well.

Looking To The FutureDespite its known benefits, nanofluids are still a relatively new development whose properties require a deeper understanding. As such, more research needs to be conducted to fully unveil the scope of its applications.

For instance, its effects on operational health and safety are still undetermined as a proper measurement process is currently unavailable. As a result, measures currently undertaken at the manufacturing site may be inadequate. However, while the small particle size makes it hard to detect, this same consideration also makes it easier for ventilation and might make it easier to remove.

At the same time, due to the costliness of production, most manufacturers have not taken to using nanofluids as of yet. Because huge fluid losses are incurred when used for flushing, nanofluids are utilised more for lubrication purposes.

However, with greater research and a deeper understanding of how it works, the scope of applications for nanofluids will most definitely expand. A subsequent increase in demand will create a push for developments in the production of nanofluids, which will hopefully, make it more accessible and available to manufacturers.

of metalworking fluid. When applied accordingly, it can help better chip removal, leading to shorter operating time and reduced tool wear.

The two tests have shown that when the right metalworking fluid is used, good results follow. The real issue here is choosing the right product. In order to recommend a product, the coolant manufacturer needs to know the application and what is expected of the metalworking fluid because even in a same operation, an identical product may not be well suited, due

Information and communication technologies have become increasingly prevalent, social and three dimensional in the

21st century. The use of Internet has become a central element in private and business environment. These new technologies can help connect people, objects and services through physical and virtual worlds.

Today, wireless technologies have brought a dynamic change in the metrology industry. Flexibility, easy use, faster performance, newer opportunities and applications are the kind of benefits these technologies provide to the industrial environment. Various wireless technologies such as laser trackers, portable measuring arms, in-process measurement

sensors and hand tools are now available in the market with each of these products offering their own special benefits and can be selected according to the intended use.

Fast Track To SuccessMetrology companies across the world have adopted wireless technology and are launching numerous products that are enhanced and operate in a smart way. The core objective of this paradigm shift is to create an ideal work environment for the metrology industry.

The laser trackers for instance, have been a long-term standard in industrial metrology. These systems lead the field in terms of accuracy and reliability. Modern laser trackers can achieve an

accuracy of 10 μm at a distance of 80 m.

Expansion or automation of the system with hand-guided scanners, wireless probes or robot applications open-up a number of possible applications. The effect: rapid and accurate measurements fed directly into production, leading to cost savings and quality improvements.

The quality team at Vestas Nacelles says that they have a lot of experience in metrology. Besides a large stationary CMM, they had used two laser trackers for many years. “The time had come to look for new measurement systems,” said Jeppe Nielsen, head of the Measuring Team.

“The old laser trackers were still working perfectly. However,

we wanted to see if there was something faster. The new tool should help us to save time and effort.” The result of the following benchmark and testing phase led to the conclusion that laser trackers were still the ideal solution for the company’s measurement challenges.

Armed With High TechnologyAnother wireless technology includes the portable measuring arm, which allows measurements to be taken directly in the manufacturing environment, where process improvements are the most beneficial.

T h e a t t r a c t i v e p r i c e -performance of these portable coordinate measuring machines when compared with CAD data or reverse engineering techniques means they are finding use in a wide range of industries.

The enha nced por table measuring arms with integrated laser scanner are now more rapid compared to previous versions, offering an acquisition speed of up to 50,000 points per second. This means that the user can move the scanner significantly faster across the object to be measured compared to previously, while maintaining high data quality that is typical for such systems.

This also applies when the surfaces are difficult to scan, for example with high gloss carbon fibre. Users can now scan up to 66 percent more surface area in the same amount of time as with previous models of these arms with integrated laser scanner.

Now, there is also an option for wireless scanning: with the help of the wireless scanning pack, all arms with integrated scanner can be operated via WiFi. In addition,

the battery system has a facility for replacing the battery while the machine is running, facilitating uninterrupted wireless operation anywhere.

Arming Production FloorsMobility, stability, low weight and high-performance laser scanning packages make the portable measuring arm an all-purpose 3D measurement tool. Absolute encoders, which assign an absolute value to each position of the arm, are a unique feature. Initialisation is not necessary. Simply take the measuring arm to the part, switch it on and start measuring.

One of the users of this wireless technology, Donovan Barnes of Habitat Industries, Cape Town, South Africa said: “With this technology, we are now capable of CNC machining

simple to complex 3D surface parts and cut our design time down by up to 80 percent. It is a productive tool with almost limitless opportunities.”

Elsewhere, Vestas Nacelles has developed a business case and found out that the use of measuring arm has proved to be very beneficial for their business.

Mr Nielsen said: “Ordering the measurement, sending the part and getting it back eventually took us days before. Now we have the results in 10 minutes. The measuring arm paid for itself in less than half a year.”

The Touch ApproachTouch probes and tool setters with radio-wave transmission Self Channel Select (SCS) technology offer precision at a work place. They provide interference free signal transmission between probe and receiver, which is absolutely vital for process-re l iable mea surements on machine tools. When using radio-wave transmission, the use of a high-penetration frequency range as well as the SCS technology ensures interference free function with a broad transmission range.

Touch prob e s me a su re workpieces on milling machines, machining centres, lathes, turning/milling machines, grinding machines, special machines and robots. Constant production quality also requires the use of reliable accurate tooling. One vital requirement is precise tool data. Touch probes for tool measurement detect tool length and tool radius directly on the machine.

Both in small businesses and in middle or large-scale production, workpieces are not only aligned, but geometries are inspected while still on the machine. Touch probes facilitate daily work, reduce manufacturing time and costs, increase the possibilities of modern machines and avoid rejects and rework.

With touch probes, deviating angular positions of workpieces can be exactly determined and automatically compensated. As such, the time-consuming axially parallel adjustment of workpieces becomes obsolete and precision is increased.

A lso, depending on the machine specif icat ion, the workpiece can be adjusted by rotating the coordinate system in the control, or by turning a rotary table, considerably shortening set-up times.

In-Process MeasurementIn tool measurement, the tool data is automatically transferred to the tool table of the control. Periodic tool checks for broken tools or wear create additional production safety. The tool setter will do this job, saving time and increasing reliability.

Tool measurement on the machine provides more precise and up to date tool data, since it takes into account the clamping forces of the tool holder and the thermal conditions inside the machine. With proven measuring cycles inside the control, measuring is both quick and safe. This saves cost and set-up time, avoids non-machining time and gives high operation and process reliability.

Wireless Technology In HandWireless probes offer robust and unprecedented stability while transferring data. Moreover, they are provided with a set of technical features unique in the market, such as a synchronised and bidirectional dialogue.

They guarantee fast and reliable measurement, both in a static and in a dynamic mode, even when the instrument is moving or is subjected to accelerations. Finally, the wireless connection contributes to a total freedom and is an asset during translations or rotations of the probe around the part to be measured.

Mobility plus high-performance laser scanning packages make the portable measuring arm an all-purpose 3D measurement tool



“These new features help incre a se the product iv it y substantially. The reduced, simplified maintenance optimises the employment of resources. The automotive and aerospace industries cannot be mistaken about these innovations and see them as major technological breakthrough,” said Marcel Bila, MD, Tesa.

Digital hand-held tools are essential in metrology. The ca l ipers, micrometers and indicators bring about advantages in terms of flexibility, readability, reliability and traceability and enhance workflows considerably.

Keeping in mind the goal of offering centralised solutions, connect iv ity and inter face s o f t w a r e s a r e o f m a j o r importance. The wireless caliper is a representative example for how customer benefit can be maximised from this wireless interface that allows a smooth and secure data transmission to the PC.

I n s t r u m e n t s w i t h t h i s technology are equipped with built-in connectivity output which offers a simple ‘plug and play’ connection. Whether using a USB or digimatic connection, data is further processed immediately.

At this stage, software that

aligns with these technologies comes into play for data acquisition, made to measure measurement program and statistical data. The software manages simultaneous measurements with different types of instrument, providing measurement protocols, control charts, statistical data, reports and data transfer. Most hand tools, height gauges, inductive probes, roughness testers and setting benches are compatible

with this software and even with a few 3D CMMs.

Connectivity is ensured with Opto USB or wireless connectors, available with many instruments. Looking at the field of 1D inductive probes and related electronic interface, metrology companies have developed h igh - tech solutions that open up wide-reaching options for the user: the versatile use of the wireless probes guarantees a high grade of flexibility in multi-gauging applications.

Flexibility is the key to most wireless technologies in the precision measurement industry. Responding to direct market needs, measurement equipment companies are looking for ways to optimise the functionality of measurement and inspection equipment. They integrate wireless options in their portfolio in order to measure all things in all ways and use a wide range of wireless technologies to reduce inspection time and costs.

Digital hand-held tools are essential in metrology as they bring advantages in terms of flexibility, readability and reliability



In-Process Measurement: The VW WayVolkswagen produces injection moulds and dies for large parts and key components at

the company’s own Components Toolmaking Division. To ensure the contour accuracy

and precision of the workpieces, they are measured using touch probes and software.

The process is carried out when the workpieces are on the machine and they are

only removed when they have been verified. This promotes smooth-running operations

and significantly shortens the overall production process. In an interview with Dirk

Strümpfler, head of the Components Toolmaking Division, he explained the key role

which component toolmaking plays at Volkswagen and the responsibility it carries.

“The speed and quality of our company’s toolmaking division must be second to

none. It means large volume throughput accompanied by a very high level of quality.”

This high quality standard calls for permanent efforts in production. The quest for

optimisation ultimately led to the use of touch probes and software.

Now the workpieces can be measured at any time, meaning that if necessary,

they can be reworked while still clamped on the machine. Time consuming second

clamping operations, which previously meant loss of accuracy, extra production

complexity and was difficult to plan, are now a thing of the past. “Now the workpiece

is unclamped only when we know it is right,” commented Mr Strümpfler.



The advent of wireless technology of late has been relentless, affecting not just the modern

developed world, but developing countries as well. In a recent report by the International Te le com mu nicat ion Un ion ( ITU ), it is est imated that there are six billion mobile subscriptions worldwide, with a third of these coming from India and China alone.

It is not just indiv iduals who are riding this wave of wireless telecommunication and networking, but businesses a s wel l . Today, t ha nk s to offshoot technologies that the wireless world has generated, cloud computing for instance, businesses can work smarter and more efficiently.

To illustrate, fishermen in Bari, Italy, have recently turned to cloud computing to access a virtual ‘fish market’, allowing them to sell their catch directly from their fishing boats. This helps to reduce an oversupply of fish, since they are better aware of the real-time demand from wholesalers and restaurants.

Such technolog y — and the subsequent elimination of inef f ic iency in the data collection process — can mean significant savings if repeated for the metalworking industry, as companies push for greater productivity.

The days when workers are restricted to a certain work area to provide timely inputs using a network computer will soon be a thing of the past. Instead, the future will allow workers the flexibility to do this from just about anywhere.

regulation and a shrinking pool of qualified workers, it has become increasingly important that manufacturers improve worker productivity.

O n e v i t a l a s p e c t o f productivity is communication, both internal and external. Communication, whether in the form of inventory data or design review feedback, is often needed to be circulated quickly throughout the company. With wireless broadband, there is now improved data visibility, allowing for better collaboration across all levels of management.

This can also lead to greater transparency, which reduces the need for highly-qualified personnel to travel frequently to e n su r e m a nu fa c t u r i n g objectives are met. Through the combination of wireless i n f ra s t r u c t u re a nd R ad io

Frequency Identification (RFID), the corporate office of a company can now keep track of project deliverables in a remote factory or warehouse.

This paves the way for a reduction of manufacturing and hiring costs, as companies site their corporate offices in developed countries where there is a ready supply of managerial talent and business infrastructure, while leaving large -scale metalworking or manufacturing operations in developing nations with an abundance of low-cost labour.

Implementation IssuesTheoretically, a company in Singapore that manufactures metal fittings, for instance, could source for its engineers a nd te chn ic ia ns f rom t he relat ively educated labour

pool found locally, and use wireless technology to transmit imp or ta nt i n for mat ion or monitor production processes in Malaysia, Thailand or China, where general workers would be more readily available.

While the idea may sound feasible, its implementation may not be as straightforward. In such an environment, safety breaches may be likelier, resulting in needless incidents. To counter this, it may be necessary for machines of the future to work smarter, ‘sensing’ when an operation is done in an unsafe manner, and automatica l ly shutting itself down.

current network speeds may be insufficient to allow clear images on a smooth feed, with it only being possible in the future with further technological gains.

In addit ion , other non -engineering issues also need considering. Would workers work as well without supervisors to manage and guide them? Would they be as motivated and stringent with a company’s standard operating procedures? If worker performance falls in the absence of supervisors and other management staff, savings from such wireless monitoring may count for little.

Solutions For The Oil & Gas IndustryWhile the wireless technology described in this article may seem like an image from the distant future, there already exist current business practices which leverage on the solutions available today. In the oil and gas industry, RFID technology has in recent years been used to automate several important inventory applications, allowing companies to minimise downtime due to shortages in parts.

R F ID tags are becoming more prevalent in such an environment, given their ability for significantly greater data capacity over other prevailing, older models, such as bar code labels. In addition, RFID tags can

be read without a line-of-sight reader, making them easier to use and more efficient.

There are already several areas within the industry which have benefitted from the use of RFID. The monitoring of installed pipelines can now be done with fewer employees, and does not have to be as time-intensive and expensive as it once was.

Using RFID tags on flanges, gaskets and bolts of a pipeline, operators can tell how old each part is, its maintenance ‘history’ and if it needs to be repaired or replaced. This reduces incidents of pipeline leakages and other catastrophes.

R F I D ha s a l so a l lowe d for the wireless tracking of personnel working in hazardous environments. In the event of an emergency, safety managers can quickly ascertain if all the workers on board a rig or platform have been safely evacuated. They can also determine where missing workers are, allowing for quick rescues which may have been impossible before.

While wireless technology may not be fully embraced by all the industries related to metalworking, its potentia l is undeniable. As the world g row s e v e r s m a l l e r w i t h increasing globalisation, and as competition grows ever more intense, only time will tell how quickly companies adopt this technology.

While it may certainly makes processes and machines work smarter, there is still much that needs to be done before it can make a firm impact on the world of metalworking. Nevertheless, if and when it does, the savings accrued from efficiency and productivity will be significant.

Welding is the process of joining two pieces of metal together by fusing the surfaces

with a filler metal brought to a molten state by the heat of a welding arc. Since weld failures can be catastrophic, such as in a ship or bridge, most welds must be free of defects to ensure good quality.

The most common weld defects are cracks, inclusions (trapped gas or other contaminates such as slag and rust), and incomplete weld penetration or fusion. When these defects are found, they must be removed and replaced by a new weld. This is typically done by grinding or gouging.

When it comes to speed and productivity, gouging is the preferred method for the quick and easy removal of welds. Besides weld repair, gouging is commonly used for scrapping or dismantling, as well as ‘back-gouging’, which is the process of removing the slag layer for multiple-layered welds.

Several metal gouging solutions exist in the market today, and selecting the right technology allows engineers to remove and repair welds with greater ease.

In Asia, hand grinding, carbon arc and plasma are the most widely used gouging technologies. And although carbon arc has long been

seen as a sufficient gouging system for a variety of needs, plasma is fast-becoming the gouging solution of choice as technology improvements in recent years have made it easier to use and more productive.

Gouging MethodsIn carbon arc gouging, an electric arc is generated at the tip of a carbon or graphite electrode. Heat generated then melts the metal, and the molten form is removed by a blast of air to form a groove. This process can be used on mild steel, cast iron, nickel alloys, copper, and aluminium, but is not suitable for stainless steel, which will corrode if gouged using a carbon arc.

Plasma gouging involves blowing an inert gas out of a nozzle at a high speed. At the same time, current from a power supply forms an electric arc through the gas, ionising the gas

to create a plasma arc. A plasma arc can gouge and

cut any electrically conductive material, and is most frequently used on mild steel, stainless steel and aluminium, giving plasma an advantage over carbon arc. Plasma systems can also gouge or cut metals that are dirty, painted, or rusted.

With this basic knowledge about carbon arc and plasma, companies in Asia may be able to instantly decide on which gouging system to use based on their critical business needs. But for more specific factors such as ease-of-use, pollution, cost and productivity, this article explores the comparisons that companies should consider before deciding whether carbon arc or plasma is the best way forward.

Ease-Of-Use & Gouge QualityIn recent years, the ease-of-use of technical processes has been gaining importance as a key decision factor in Asia, primarily because it minimises training, improves safety, and ultimately increases profitability. Comparing carbon arc to plasma, operators are able to get used to the latter much more easily.

When using a carbon arc for gouging, it is difficult to control the electric arc. So, it is not uncommon to have too much metal removed or to wind up with extra carbon deposits on the base metal.

This is the case even for experienced operators. Plasma, on the other hand, requires just some practice in order to achieve

a smooth, clean, consistent gouge. Consequently, secondary operations, such as grinding, are often not required to improve the gouge surface finish when plasma systems are employed.

Also, plasma is able to gouge a wider range of metals. It is suitable for both ferrous and non-ferrous material that is electrically conductive, as well as metal that is in any condition.

Carbon arc gouging, however, can only be carried out on limited types of metals. This means that welders who utilise plasma systems need only to use a single equipment to work on a variety of metals, while carbon arc users may have to switch between systems, depending on the material types they are working on.

PollutionProviding a safe work environment is of increasing importance to

manufacturers in Asia. For carbon arc gouging, the air blast often vaporises molten metal into fine droplets, producing excessive fumes. These emissions may consist of metal vapour, carbon dust, and metallic by-products, which can cause health problems. With plasma gouging, on the other hand, liquefied metal is pushed out of the groove in a milder manner, so less fumes are produced.

In addition, carbon arc gouging, like mechanical gouging, is relatively loud. Although ear protection is recommended for plasma gouging, plasma is a quieter alternative that is typically 5 to 10 decibels lower.

Cost & ProductivityThe initial capital cost of a carbon arc gouging system is generally lower than that of a plasma system. However, because plasma is typically able to gouge four

times as fast as carbon arc is able to, with little or no grinding needed for clean-up, the cost per part produced is smaller. Also, consumables for plasma systems are able to last a longer time. Considering all these factors, plasma gouging becomes the more economically efficient option.

In addition, plasma systems can be used not just for gouging, but for cutting as well. End-users have the potential to derive greater value from their equipment and may more rapidly realise a positive return on their investment in plasma.

In Asia, carbon arc and plasma gouging are both well-established processes for gouging metals. Each has its own advantages and challenges, and choosing between the two depends on individual companies’ specific business needs.

The development of new weld processes for use in mechanical engineering, shipbuilding and vehicle

manufacturing has always centred on the need to boost productivity. In the past, particular attention has been paid to shortening the welding times by increasing the welding speed, and/or to minimising the amount of post-weld machining and straightening work needed in the welding of large cross-sections of thick-walled plates.

A l o n g s i d e s i n g l e - w i r e processes with higher deposition rates, such as submerged-arc and electroslag welding, efforts have focused on developing systems for welding with several electrodes simultaneously.

These systems are called the double-wire and tandem welding processes. The greatest advantage of both types of two-wire process lies in their significantly higher deposition rate and welding speed, and lower thermal input.

A further advantage of welding with two wires in a shared weld-pool is that the weld-pool is larger, and solidifies later. Also, two-wire processes make it possible to increase the gap-bridging ability by turning the welding torch sideways, allowing broad wetting to sidewalls in the top pass with no need for oscillation.

S i m u l t a n e o u s w e l d i n g with several electrodes has long been established as an economically efficient method of high-performance welding. In practice, however, it has become apparent that users have difficulty identifying the correct parameters. The reason lies in the complexity of the welding systems and processes that have been available until now.

Before going into that, we take a look at some of the differences between double-wire and tandem welding processes.

Double-Wire WeldingIn double-wire welding, otherwise known as parallel-wire welding, two wire electrodes are melted off using a shared torch in which both wires are at the same electrical potential. Depending on the power requirements, welding is carried out either with a shared power source or with two separate ones. Separate control of the weld processes is not possible in either case because only one common

voltage is available for use as a control variable.

The two electrodes are therefore only melted off at an approximately equal wirefeed speed. This high deposition rate is not needed in all welding applications, for instance, on lap-welds with small seam cross-sections. However, thermal input is still high despite the faster welding speed, and this can make work more difficult.

Tandem welding can produce more flexibility and better performance. By Dipl Ing (FH) Franz Joachim Roßmann, for Fronius

The high welding speed can also cause problems in itself, such as undercutting. To prevent this, the arcs must be set as short as possible. On the one hand, it is not possible to control dip-transfer arcs in double-wire welding. On the other hand, when the arc is longer, there will be more interference. As such, negative effects such as spattering and process interruptions are almost impossible to prevent. Tandem welding is the better alternative here.

Tandem WeldingUnlike in double-wire welding, tandem welding always uses two mutually insulated power sources and a torch with isolated current conduction. In this way, all common types of arc (dip-transfer, spray and pulsed) can be combined in one and the same system. Each arc voltage can be measured separately and used as the control variable.

For maximum stability, a tandem welding process that (eg: TimeTwin) synchronises two arcs used in pulse welding in a 180 degree phase opposition is used. Although the wirefeed speeds can be diverged here, this is only possible within comparatively narrow boundaries.

Due to the phase displacement, the weld-pool stays quieter in TimeTwin — there is less spattering

than in double-wire welding or conventional tandem welding, and the arcs are more stable. Tandem processes are generally characterised by lower thermal input than double-wire processes.

With some welding-tasks, even this decreased thermal input may still be a problem. Fillet welds are a good example: if the weld-pool becomes too fluid, the seam will sag when welding is performed on larger seam cross-sections in the PB position or in out-of-position work. In these welding positions, process stability also suffers. Cases such as these call for a more stable process in which the thermal input is even lower and can be precisely adjusted.

More Flexibility & Control In Tandem WeldingFor appl icat ions in which greater process stability and uninterrupted control of the weld process across the entire power range are required, a tandem welding system may be more suitable (Figure 1).

This welding system is equipped with two digital power sources that work completely separately from one another. This allows the weld processes to be individually adju ste d to t he d i f ferent applicational requirements in each case, and also means that — within the given physical limitations —

any wirefeeder can be chosen. As a result, widely diverging

wirefeed-speeds can be set. It is even possible to utilise entirely different weld processes. This twin-wire solution allows users to exploit two Cold-Metal-Transfer (CMT) processes, or combine a GMA pulsed-arc welding process (‘Lead’) with a CMT process (‘Trail’), all within one single system (Figure 2).

A characteristic feature of the CMT process is that the electrode is moved rapidly back and forward, in a controlled manner, while welding is in progress. The short circuit (when the electrode touches the weld-pool) initiates the reverse motion of the electrode. After a defined arc-burning duration has elapsed, the wire changes direction and is moved back towards the workpiece. Unlike a pulsed or spray arc, the droplet is now detached in a controlled manner during the short circuit.

In CMT, the arc length is subject to little or no fluctuation, as the wire is retracted by a defined distance independently of the stickout. The heat input is significantly less compared to a conventional dip-transfer arc, as the short circuit is not broken under high current-flow (as it would be in a conventional dip-transfer arc), but at a low amperage when the wire is retracted.

Figure 1: The CMT Twin tandem welding system has two independently functioning digital power sources

Figure 2: CMT Twin process sequence when the pulsed-arc and CMT processes are combined

This controlled shedding of the droplet into the weld-pool means that little or no spattering occurs, making the process even more stable in comparison with conventional (pulsed) arc processes.

In CMT Twin, these positive properties can be combined with the advantages of a GMA pulsed-arc welding process: for example, the first (‘lead’) wire electrode can achieve deep penetration with a pulsed arc and/or a high welding amperage, while the following (‘trail’) electrode works in CMT mode and fills the seam as needed, with reduced wirefeed speed and heat input.

As the CMT Process exerts less arc pressure on the weld-pool, with the result that the weld-pool remains quieter, there is less disturbance of the pulsed-arc process on the ‘lead’ electrode. This, in turn, allows the pulsing to be kept shorter and with higher power (= deep penetration).

The resulting welding speeds are high. In the case of a fillet weld welded at the lap joint of two 2 mm steel sheets, they can be as fast as 4 m/min (Figure 3). Due to its lower thermal input, the tandem welding system performs better than conventional tandem processes in terms of gap-bridging ability as well.

T he que st ion o f wh ich combination of processes should be chosen for the weld system will depend on the requirements

applying to each different welding task, in terms of welding speed, deposition rate and gap-bridging.

For fillet welds needing to be welded in the PB position or out-of-position, it is best to combine a pulsed arc (‘lead’) with the CMT process (‘trail’). This combination lets welders achieve ‘textbook’ results, even when welding a6 fillet welds in the horizontal-vertical (PB) position (Figure 4).

Compared to conventional tandem processes, combining the pulsed-arc and CMT processes in this way, with all other parameters remaining the same, decreases the thermal input by between 10 and 20 percent. The thermal input from a CMT-CMT combination is even lower still, meaning that new areas of application can now be opened up for tandem welding.

To give one example, CMT Twin allows out-of-position welding of root passes (Figure 5) that would either be impossible with other welding processes, or not economical. Butt-welds can also be welded much more efficiently, as the weld-pool is quieter and the deep penetration on the ‘lead’ electrode lessens the risk of fusion defects, meaning that a smaller included angle can be chosen.

Easy To HandleTo ensure a good weld right from the very beginning, (in CMT Twin) the ‘trail’ electrode does not start work until the ‘lead’ electrode process has stabilised

and the power source for the ‘trail’ electrode has received a start-up signal.

The high process stability and lower level of reciprocal influencing have made it possible for Fronius to draw up optimised characteristics for various applications. These co-ordinate the processes for users, making it much easier for them to identify the correct parameters.

ConclusionC M T Tw i n co m b i n e s t h e advantages of TimeTwin and CMT in one system. Compared to conventional two-wire processes, the advantages are high process reliability, seam quality, gap-bridging ability, speed, and the fact that only minimal post-weld machining is ever needed. Thanks to these performance attributes, the tandem welding system delivers better welding results than conventional double-wire or tandem processes.

This is seen particularly clearly when joining light-gauge sheets at high speed because the heat input do not exceed the optimum. The welding system also stands out for its ease of handling. All these many capabilities make the welding system suitable for use in the automotive and supplier industries, in shipbuilding and mechanical engineering, and in the power generation field.

Lost-wax casting is a mould part process that has been gaining popularity amongst manufacturers

in recent years due to its pliable nature in producing small lots in short timeframes. The technique permits reproduction of intricate metal objects through multiple steps, allowing several mould parts to be assembled to form a product, removing the need for a machining process after casting.

One company that specialises in producing precise parts using the lost-wax casting process is Kingparts, based in Fukuyama City, Hiroshima Prefecture, Japan. The company handles the entire production process from start to finish, which begins with the design of metal moulds, to mould making, casting, finishing, and delivery.

Typically, the parts produced are used in areas such as general industrial machinery, electronic & electrical products, machine tools, medical devices, automobiles, aircraft, measurement instruments, food manufacturing devices and defence equipment.

Shape Measurement In Quality AssuranceIn an effort to improve on casting technology, the company has invested in R&D in recent years. They increased spending on capital investment by acquiring a wax mould making machine, a core firing furnace, a vacuum heat-treating furnace, and a lost core device.

This resulted in a new die casting technology using ceramic core. The technolog y took around three years to develop,

as the company had to overcome technical difficulties of varying degrees — including the precision of joining mould and core, as well as core flexure control. But as soon as Kingparts had some success with resolving the technical issues, interest in the new casting technology picked

Engineering tolerance — you are either within or out of it. Measurements however, can benefit from a little flexibility in the form of measuring arms. By Yoshihiro Iida, marketing manager, Faro Japan

Conclusion: Efficiency of the measuring process was improved and it opened up new opportunities for the company.

up and the company started to receive a larger volume of orders from existing and new customers.

However, the company ran into a new problem after its initial success. They had to measure complex curved surfaces of parts on objects for quality control, which called for the implementation of a metrology solution.

At that time, the company ow ne d a few ga nt r y - t y p e measuring machines to perform 3D measurements. The drawback of these machines was that it was incapable of capturing all the fine details of objects with irregular curved surfaces. As such, the company chose to farm out the measurement jobs. This process proved to be time-consuming and cumbersome for product creation.

As production using the new die casting technology gained pace, the demand for 3D measurements increased. In anticipation to growth in orders, there came an increasing need for the company to possess its own non-contact measuring equipment that would enable it to conduct its own quality checks. A decision was then made to acquire a portable 3D measurement arm with multiple axis-of-rotations that emulates the versatility of the human arm.

Improving The Measuring ProcessThe measuring arm in this case is the Faro Edge. With it, the company’s technicians are able to measure objects that could not be accurately captured using traditional tools. This has a positive impact on quality improvement as the deployment of non-contact 3D measurement arm permits intricate die making, leading to precision die casting reproduction.

I n t he p a s t , u s i n g t he t r a d i t i o n a l g a n t r y - t y p e me a su r ing to ols re qu i re d the object to be turned over, moved around or measured with the aid of a jig. Repeated benchmark measurements were also necessary. But with the portability and flexibility of the measuring arm, cumbersome processes are no longer needed. This improves the efficiency of the measuring process and reduces measuring time.

In addition, issues like storage space for the jig, prolonged production time and cost have also been eliminated, leading to the emergence of other benefits. They are time-savings and cost-savings since the company no longer has to outsource the measurement jobs.

Extending The Reach To enable mass production, the company has assigned dedicated personnel to perform measurements using the arm as opposed to having two employees operating it on top of their other duties.

The focus placed on the measuring arm is not surprising given that the company has greater plans for it rather than just pure measurement.

Shunichi Kimura of Production Control Division explained: “It’s now possible for us to perform evaluation of objects such as turbines and ceramic cores. This could not be achieved with traditional techniques before. I’m looking forward to applying this technology to the next project that involves measurement of moulds or products with irregular curved surfaces such as wings.”

With an eagerness to take on new tasks involving the use of non-contact 3D measurement instrument, he added: “We have received orders that require us to perform reverse engineering. Even though the number of projects is very small at the moment, I look forward to using the Faro Edge more for this new field in the future.”

Mould and die are the cornerstone of mass production and industrialisation in

modern societies, and one of the tools necessary for industries to run mass production. They are widely applied in the automotive, instrument and meter, electronics, home appliance, aerospace and petrochemical industries.

A s the se products a nd equipment consist mostly of parts, units (sub-assemblies) and components, which are used in

large volume, mould and dies are supplied virtually to every company manufacturing such equipment, products, parts and components.

Moulding, in the modern sense, began in the early years of the 20th century and progressed rapidly a f ter the 1930’s in industrialised countries. The industry expanded rapidly in the 1940s because World War II created a huge demand f o r i n e x p e n s i v e , m a s s -produced products.

Accuracy Of MouldAs die and mould help in the fa b r ic a t io n o f p a r t s a n d components, their accuracy subsequently determines the accuracy of the parts and components manufactured.

For example, the notched tap of aluminium cans used in package beverages poses a danger to consumers. These cans are finished within the accuracy of 1 micron, while the accuracy of the corresponding mould is in the magnitude of 0.1 micron.

Augustine Quek analyses the fortunes of the mould and die industry in this special focus.

To Change With The Times

The Mould & Die Industry

IndustryFocus


Local ConnectionOne characteristic of the industry is that customisation of the mould and die tends to be done locally. Tool-making requires extensive collaboration with the customer, due to the high degree of production customisation. Therefore, a high frequency of interaction between mould and die makers and their customers is necessary, with face-to face discussions usually essential.

With the need for these frequent business meetings, it is natural for manufacturers to prefer contracting tooling suppliers located near their facilities. In addition, the industry also traditionally consists of many family-owned companies accustomed to servicing nearby manufacturers.

All these factors add to a situation whereby the companies are not particularly ready to compete in a rapidly globalised environment as they could not adapt quickly enough to foreign competition.

Globalisation — A Disruptive Trend? However, globalisation is making this traditionally competitive business even tougher. As a result, die and mould makers must rethink both their short-term and long-term strategies.

According to the International Trade Administration (ITA), US Department of Commerce estimated 60 percent of stamping dies and 40 percent of plastic moulds are employed directly or indirectly by automakers around the world, making them particularly reliant on the transportation market.

However, automotive makers around the world are shifting their manufacturing facilities to overseas locations while US automakers, particularly General Motors and Ford continue to weaken. These trends have negatively impacted the US mould and die makers, particularly small, family-owned shops.

In fact, according to several sources, an estimated 150,000

tooling jobs have been lost in North America since 2000 due to offshoring. Additionally, the US injection moulding machinery market has shrunk by almost 50 percent over the last five years, according to ITA. Furthermore, this industry is extremely capital intensive. Highly sophisticated machine tools and manufacturing technology are crit ica l for toolmakers to reduce labour costs and to improve efficiency.

Traditional strategies no longer suffice because of the rapid spread of offshore outsourcing, not only in the purchase of tools, but also relocating part of the production to lower cost countries in Asia such as China and India.

Mould and die manufacturers who face massive cost pressure outsource not just to follow their customers but also to serve new customers in the target markets. According to the ITA, cost savings from 40 percent to 70 percent are possible, but the process of finding the right supplier of mould tool and mould material is intense and the necessary input is very high.

Mould & Die In ChinaThe relocation of mould making companies to China has caused the rapid development of automotive, home appliance and IT industries in China. Between 2005 and 2011, the Compound Annual Growth Rate (CAGR) of mould output in China reached 9.7 percent, while that of sales registered 12.6 percent, according to China Mould and Die Industry Report, 2011-2012.

The report also revealed that the mould and die output of China saw a slight increase to 9.82 million sets in 2010, compared to 9.7 million in 2009. With the export value totaling US$2.196 billion, up 19.15 percent over the preceding year, trade surplus was realised for the first time.

In fact, statistics showed China has the third largest mould industry in the world based on

total output, after Japan and the US. According to International Mould Association secretary-general Luo Baihui, the Chinese mould and die market is expected to reach CNY350 billion (US$56.5 billion) in 2015, with total sales in 2011 reaching CNY164 billion.

Currently, automotive and electric appliances already account for over 80 percent of the entire market. For example, the total number of auto parts needed to be moulded for a car is about 4,000 sets, with total value of CNY200 to 300 million, while a refrigerator requires about 350 sets of moulds in all, which has a value of about CNY4 million.

Presently, major mould and die companies that relocated and have established a presence in China are mainly Japanese automakers and enterprises, including Toyota, Toshiba, Sharp, Honda, Mitsubishi and Fuji. Other mould manufacturers from Japan that have also accelerated their business development in China include Ogihara, Kuroda and Uyemura-Solar.

Mould & Die ManufacturingIn order to thr ive in this competitive environment, die and mould makers have mostly specialised in particular areas, beefed up services, added value

to products, sought niche markets, and increased mouldmaking capabilities. Similarly, mould making machines will become increasingly sophisticated in the areas of processes, technology, and specialisation.

For example, Makino’s high-speed machining centres can mill and make moulds out of the hardest steels (60+ HRC), eliminating grinding and polishing in the process.

Its Super Geometric Intelligence (SGI.4) controls, allow long, complex mould programs to be processed at fast speeds and with high levels of accuracy and finish.

The company claims that the control can help reduce the high-definition 3D milling of dies and moulds by an average of 15 percent compared to previous versions of this technology, resulting in a reduction of some cycle times by as much as 30 percent. Forging dies that once required eight setups, 40 machine hours and a six-day lead-time can now be executed with a single setup and completed under four hours.

Tackling The Niche MarketTo combat low-cost overseas competition, mouldmakers can specialise in high-growth market segments such as medical, domestic automotive, packaging

and military & defence. For example, medical moulding

is an ideal process for more sophisticated mould manufacturers to specialise in because of the complexities of working with local regulators. It also is becoming more important as the population ages and requires more medical care.

T h e r e f o r e , t h e m o r e technologically advanced countries, such as Japan, the US and Germany, can still maintain leading positions in various niches. With their well-established R&D capabilities and design capacities, the high-precision and complex nature of mould and die development is still better understood and improved upon in these countries.

The globalisation of markets is the most important feature in today’s mould industry. Successful mould making companies are facing the challenges head on by diversifying their die and mould markets in order to find new business.

They are also transforming in order to strengthen their overall competitiveness. On a grander scale, the mould and die industry will continue to restructure itself to become more dynamic and global in order to compete for business and survive.


There are more mould makers specialising in high-growth market segments such as military and defence in a bid to differentiate themselves from low cost competititors.

There are plenty of ways to define sustainability a n d s u s t a i n a b l e m a n u f a c t u r i n g .

L i ke w i s e , t h e r e a r e a l s o different motivations to pursue sustainable manufacturing. A noble definition of sustainable manufacturing by the National C o u n c i l f o r A d v a n c e d manufacturing is that it ‘meets the needs of the present without compromising the ability of future generations to meet their own needs’.

Living within our means seems to be the message here but the bottom line is that it is a tough task to quantify what is sustainable and what is not. In a presentation on remanufacturing, which is a subset of sustainable manufacturing, Dr Ta n Boon K iat , sen ior industry development manager, Susta inable Manufactur ing Centre, SIMTech spoke at length on the impact of remanufacturing and various considerations that should be undertaken before a business goes down the path of remanufacturing.

Disrupting Traditional Beliefs With New ConceptsReduce, reuse and recycle are three terms that are commonly h e a r d a n d p r e a c h e d . I n order to achieve sustainable ma nufactur ing, three new terms like recover, redesign and remanufactur ing were introduced, and for good measure too as there have been an increasing number of disparaging

voices heard questioning the virtue of recycling.

In terms of industry ecology at least, recycling may not be what it seems. “Recycling may not be good because you are dumping a lot of energy back into the material in order to get raw material,” said Dr Tan. “Most of the time, it does not work. As such, many companies are struggling to make recycling viable for business,” he added.

H e p o i n t e d o u t remanufacturing can be used instead as remanufacturing concepts harness the potential of the remaining material (old part) and the carbon footprint used

to remanufacture a part is lower compared to recycling a part.

Identifying The DistinctionAlthough remanufacturing is not a new term, it always seems to have a thin mysterious veil wrapped around it. It may be the subtlety of the term but the unfortunately thing is that without understanding and appreciating the differences between terms like recycle and remanufacturing, it is difficult to practise let alone benefit from remanufacturing.

“Rema nufactur ing is a n innovative model rather than a progressive reduction model like lean and green manufacturing. In

lean manufacturing, there is more bias towards waste reduction. Green manufacturing on the other hand, leans towards the environment.” According to Dr Tan, some companies may see green manufacturing as a sacrifice and as a result, the adoption rate is not high.

In a bid to illustrate what remanufacturing is, Dr Tan took time out to define repair and recondition. According to him, repair refers to returning the broken or faulty components to a usable condition. Warranty issued for repair is generally much less than that of new components.

Reconditioning is usually applied to worn parts that are not yet critically damaged. Again, it is restored to a partial functional state. In remanufacturing, parts are returned to a full functional state with full warranty. These

parts can come from both worn and damaged parts.

Application Is Key The talk on remanufacturing and its benefits is well and good but it would be ultimately counterproductive if it cannot be applied properly. Remanufacturing is said to be suitable for parts that have high intrinsic values. Good examples would be aerospace parts, machine tools and train rolling stock.

Asia Pacific Metalworking Equipment News understands that large machine tools are prime remanufacturing examples because there are “plentiful

amount of materials left at the machine’s end of life,” according to Dr Tan. Staying in metalworking, he said companies are also trying to look into the remanufacturing of cutting inserts due to the scarcity of tungsten carbide.

Challenges Of Remanufacturing“Remanufacturing was initially done to reduce costs of automotive parts, not for sustainability,” said Dr Tan. The commercial aspect of manufacturing is a very real one and it can force businesses to prioritise long term financial viability over the fundamental

In terms of industry ecology at least, recycling may not be what it seems.

noble values behind sustainable manufacturing. It is therefore realistic to consider the financial ramification of remanufacturing.

“As a business challenge (remanufacturing), you do not have the certainty of a used product coming back to you if you do not have control of the whole value chain,” said Dr Tan.

In order to get around this problem, he said it is better to design for core collect, ie: calculated ways to get back the used products in order for remanufacturing to take place.

On the operational front, even when a supply of used parts is secured, it is often difficult to control the frequency and quantity of supply. As such, planning for different types of manufacturing equipment can be challenging because of uncertain demand.

In addition, the decision to scale up or down production hinges on core collection demand, on top of existing demand from customers. These uncertainties result in complicated production planning and execution.

The last few challenges to overcome are technical in nature. A typical remanufacturing process starts with the dismantling of

the component, followed by the sorting and cleaning of individual parts, inspect ion, and the identification of parts that cannot be used anymore. Refurbishing comes next before assembly and quality control. After which, the final part is delivered.

Dur ing the d isma nt l ing a nd i n sp e c t ion s ta ge s o f remanufacturing, a lot depends on t he e x per ience o f t he skilled workers in identifying components. This reliance is also seen at the inspection stage. Since it is too expensive to rely on equipment like the CMM, a worker’s judgment is called into action. Finally, some remanufactured parts may have different dimensions, causing problems in assembly.

The challenges mentioned do not address some other issues faced by certain manufacturers. In S ingapore for exa mple , specia l ised processes l ike machining, coating and heat treatment need to be outsourced because the technology level needed in remanufacturing is usually higher than normal manufactur ing, potent ia l ly creating another problem as transportation and other human factors come into play.

Dr Tan said there is no fix model for remanufacturing that is guaranteed to work


Carry Out Remanufacturing On Your Own Terms L i k e a t a i l o r e d s h i r t , remanufacturing will fit nicely if measurements are done correctly and fitting is done properly. Most important of all, the person wearing the shirt must already have a clear picture how he wants his shirt to be.

I n co n c l u s i o n , D r Ta n said: “There is no fix model for remanufacturing that is guaranteed to work. Same models may work for some industries in some countries but it won’t work anywhere else. Other factors like legislations also play a part. There is no one size fits all solution in remanufacturing.”

He said it is better to list down favourable conditions and identify the types of models proven successful in order for a company to decide whether it should go into remanufacturing.

Finally, he also revealed SIMTech has in a research stage a Remanufacturability A ssessment Study to help companies decide through various factors to see whether a product, component or module is worth remanufacturing.

According to Dr Tan, recycling requires a lot

of energy, which makes the recycling business

unsustainable for some companies

The global market for motorcycles, including electr ica l ly-powered machines, is forecast to

expand 7.2 percent annually to 134.5 million units in 2016, when industry revenues will reach US$90 billion. The Asia Pacific region, which predominantly utilises small and inexpensive motorcycles, will continue to dominate worldwide demand, representing 84 percent of all units sold in 2016. These and other trends are presented in World Motorcycles, a study from The Freedonia Group.

World sales of motorcycles will be stimulated by rising standards of living in developing nations. China will remain by far the largest national market, with India and Indonesia also important based on large populations with the means to purchase inexpensive motorcycles.

There is a strong correlation between average income levels and motorcycle demand up to a certain point. In emerging economies, strong growth in

motorcycle sales is triggered once certain per capita income thresholds have been reached.

Light Motorcycles Lead The WayDue to the superior fuel efficiency these machines provide compared to automobiles and other light vehicles, motorcycle demand gains will also be supported by higher petroleum costs.

Furthermore, a rebound from the 2007-2009 recession in developed countries like the US will lead to higher product sales, particularly of medium and heavy motorcycles, as economic co n d i t i o n s b e co m e m o r e favourable and consumers begin to purchase these expensive recreational items again.

As a result, medium and heavy Internal Combustion Engine (ICE)

motorcycles will account for nearly 20 percent of 2016 demand in dollar terms, even though they will make up less than two percent of global unit sales.

Light motorcycles will remain the single largest ICE product segment in unit terms because they offer a mix of the best attributes of smaller (lower cost) and larger displacement models (more power).

I C E sco ote r s , mop e d s , and motorbikes will comprise approximately one-third of total product sales in 2016, supported by their low cost and easy maneuverability in congested urban areas. Sales of electric bicycles (e-bikes) and electric motorcycles (e-cycles) are expected to grow roughly in line with ICE motorcycle demand through 2016.

Demand For MotorcyclesThe number of motorcycles will increase due to rising standards of living and higher petroleum costs. By Lee Steinbock, industry analyst, Freedonia Group


There is a strong correlation between average income levels and motorcycle demand up to a certain point.

In today’s processing plants, control loops have been incorporated into production pro ce sse s to e n ha nce

productivity while saving time. Each loop is responsible for one part of the process, such as controlling temperature levels or flows, and a typical plant can have a combination of up to hundreds and thousands of such loops. The entire production process is streamlined with the addition of these automated enhancements, with one example being level sensors.

Level sensors can be used across a variety of industries, which includes the aerospace, automotive, mining, construction, medical, food and beverage as well as the oil and gas industry. It is part of a metrology system that facilitates automation by measuring substance levels and transmitting the data to a controller, which then sparks off a set of actions.

Suitable for measuring levels of liquids, solids and slurries, level sensors can be categorised into two types, by either measuring point or continuous values. The former is mostly used for detecting excessively high or low levels, by measuring whether levels are

above or below a particular point. Continuous level sensors, on the other hand, measure the exact amount of substance as long as it is within the specified range.

A Well Oiled ProcessLevel sensors are markedly utilised in the petrochemical and oil and gas industries. It is employed during the oil refinery process, in addition to storage and transportation. Most of these level sensors are used for safety purposes. For instance, it can be used to check the amount of rain or groundwater that has seeped into a basin, by measuring the proportion of oil and water. This helps to determine whether the facility is a danger to the environment.

Other functions include inventory control, mud logging, leakage monitoring, overfilling protection and automatic tank gauging. It is also used to detect and pump out water during the oil distillation process so that the distillate does not get polluted. The ability to measure substance levels within various parts of the process has resulted in a greater accuracy and accessibility to real-time information.

Ultrasonic and radar level

sensors are just some types of instrumentation used for these applications. Both can be used for measuring point or continuous values.

The Sonic BoomUltrasonic sensors are widely used in measuring the levels of liquids, particularly so as it is a non-contact medium that senses liquids with high viscosity, as well as slurries. It is also favoured for the combination of high functionality and low cost. It is suitable for the oil and gas industry as the instrument does not have any direct contact with the compounds, which are mostly volatile, and are therefore less prone to failure as well.

The basis of ultrasonic sensors are making use of high frequency sound waves to determine the level of substance, through the time taken for the echo to bounce back to the sensor. The distance of the sensor from the fluid can then be calculated using the speed of sound.

However, a disadvantage of using ultrasonic sensors is that measurements might not be truly accurate. As the reflection of sound waves are affected by variables

such as moisture, temperature and pressure, allowances and corrections have to be applied to the level measurement for increased accuracy.

Microwave SensorsInstead of using sound waves for level detection, an alternative s e n s o r e x i s t s t h a t u s e s electromagnetic pulses. Known as the microwave or radar sensor, this form of instrumentation retains the benefits of ultrasonic sensors without its pitfalls.

For instance, it is impervious to temperature and vapour, and is therefore suitable for use in environments that are moist or warm. The use of electromagnetic energy has also enabled the use of these sensors in vacuums, as air molecules are not required.

There are basically two types of microwave level sensors, the

first of which is non-invasive and measures distance based on the frequency of reflected signals, while the other is invasive and uses a probe to direct the microwave to the bottom of the vessel.

The non-invasive method can be separated into the Frequency-Modulated Continuous Wave (FMCW) type or the pulsed time-of-flight method. The former sends a linear sweep at a fixed bandwidth and time, and the frequencies of the reflected and transmitted signals are combined to form an accurate measure of liquid level. Pulsed time-of-flight works on a similar principle to ultrasonic sensors by measuring distance based on the time the pulse is reflected.

Alternatively, the invasive method, otherwise known as guided-wave radar, is based on time-domain reflectometry. Hundreds of thousands of pulses

are generated down the rod, or equivalent, which causes a change in impedance in the dielectric qualities of the measured fluid. This results in a wave reflection, and the transit time of the pulses are used to measure liquid levels. This method is more efficient as the signal is less degraded by external circumstances, such as the presence of obstructions. However, due to it being contact-based, there is a risk that the probe might be damaged or corroded.

Within the oil and gas industry itself, level sensors have many different uses, from pure tank gauging to the separation of immiscible liquids. As such, the type of level sensor that should be employed depends very much on the specific application it is used for.

Event Review:

MTA 2013

Ov e r 1 2 , 5 0 0 t r a d e attendees including trade visitors, exhibiting s t a f f , c o n f e r e n c e

delegates and speakers, and members of the press visited M TA 2 013 over fou r day s . Responding to the Singapore government’s urge to adopt adva nced technolog y a nd complex machinery in order to improve productivity and capabilities, precision engineering and manufacturing sectors in Singapore are moving away from low value mass manufacturing and towards servicing high value industries that require complex equipment and machinery.

Industry players need the latest technology and know-how to level up their capabilities to meet the demands of these industries. It is therefore not surprising to see a fair bit of new technology and launches at the show.

3D printing is one example. An emerging technology that has been earmarked by the government as the future of manufacturing, the technology is beginning to attract interest among local organisations.

Toh Cher Lek, R&D Director of New Kinpo Group, who came to the show to source for 3D printer


suppliers commented: “MTA allowed me to find new 3D printing suppliers and vendors, and was a great platform for me to learn about the latest in 3D printing and also a new type of 3D printing — 3D metal printing. Exhibitors were reputable, professional and efficient in their dealings.”

Generating SalesAs the four-day event drew to a close, ‘Sold @ MTA’ signs proudly adorned many of the machines on display at the show floor.

“We brought a mixture of grinding, turning and cutting machines to MTA2013. So far we have sold six out of seven machines to automation and precision engineering companies. A ltogether we made about S$800,000 (US$647,000) in sales, we are extremely happy,” said Simon Teo, director of ST Machinery.

Some other exhibitors who managed to secure business transactions at the show include Accrington Precision Machine Tools, Anhui Krras Machine Tools, DKSH Technology, EHN & Land, Flexspeed, Gustav Gockel Ma schinenfabr ik , Hexagon Metrology, Ichi Seiki, IM Machinery Asia, J-Tech Machinery, Makino, Mitutoyo, Newserv Machinery,

Pryor Marking, Rotec Singapore and Taipei Industries.

Good ResultsOverall, William Lim, project director for machinery events at Singapore Exhibition Services, organiser of the show gave it a success rating of 8 out of 10, and full marks for the quality of visitors. This is because senior technical engineers from industry big wigs and key buyers such as Amtek Precision Technology, Becton Dick inson Medica l, Cameron, GE Aviation, Hamilton Sundstrand, Honda, PerkinElmer, Pratt and Whitney and SMB Switchgear & Engineering among many others were seen combing the show floor.

With a select ion of 500 exhibitors from 31 countries and regions exhibiting their latest products, visitors to the show were in the prime position to expand their business networks and form business partnerships. The show will return from April 14 – 17, 2015 at Singapore Expo.

Leong Kim Huat (L) & Lim Boon Choon



‘Exposure’ is the key word for Hexagon

Metrology at MTA2013. According to Lim

Boon Choon, VP of Hexagon Metrology Asia

Pacific, it is important for a company that

has numerous brands under its umbrella to

be seen as a single entity.

He said: “It is very important for our

customers to see our new machines and to

see us as one Hexagon. Many may know us

from the days gone by as Leica or Brown

& Sharpe but the branding is now Hexagon

Metrology. As a company, we own all these

technologies and companies.”

He then went on to say that MTA is

an important show for metrology and it is

essential to be involved.

New Technologies On Show

The focus placed on this event has seen

the company bring three new machines to

the show.

“We are displaying a number of

machines over here for the first time.

For example, one of them is our vision

machine (Optiv Lite). We have a line

of vision equipment that can be used

for vision inspection,” he said. APMEN

understands that the Optiv Lite is a vision

measuring machine used for non-contact

inspections accurate to the micron level.

The camera based measurement machine

can also switch to a contact mode for

tactile measurement.

Another new product at the show is

a shop floor CMM. Leong Kim Huat, GM

of Hexagon Metrology Asia Pacific said:

“The 4.5.4. SF CMM is one for the shop

floor. It can operate in harsh environment

as the temperature requirement is not

as high.”

The final new machine at MTA2013 is

the Global Performance 3.4.3. According

to Mr Leong, it is for minute parts that

require high precision. He said: “The Global

Performance 3.4.3. is a CNC CMM, which is

suitable for electronic components that are

small and precise.”

In addition to the machines, the

company is also featuring a measuring

device with a twist as Firoz Khader,

r e g i o n a l d i r e c to r f o r p r e c i s i o n

measurement instrument, Hexagon

Metrology Asia Pacific explained: “This

year, we are launching a product called

the Twin-Cal (Tesa Wireless Interface

Caliper) IP67 electronic caliper. It is a

radical departure from the traditional

connectivity solutions. The customer

buys one product but with it, he has an

evolutive solution as well. This is due

to the fact that he is not only buying

a system that allows him to do simple

measurements; he buys an option as well.

As such, he does not have to buy another

product when he needs connectivity to

send data some months down the road.”

Hexagon Metrology: Coming Together As One

Unisig To Expand The Oil Tool Market In Singapore

Exhibiting for the first time at MTA is Unisig,

a company that manufactures deep hole

drilling systems. Jeff Price, VP, sales and

marketing of Unisig, told APMEN in detail

what his company is all about. He said:

“We produce two types of machines. The

B Series is used for the drilling of large

diameter on-centre holes. They use BTA

toolings like solid, trepanning and counter

boring tools.”

The other machines in use in the

Singapore market now are used for drilling

small diameter off centre holes with gun drill

tooling. He said: “We have the USK and the

USC series machines that are used for small

diameter holes off centred up to 200 times

the diameter of the depth in some cases.”

Business In Singapore

Mr Price revealed he was at the previous

edition of MTA two years ago. It was then

that the company decided to exhibit at

the show, because they saw the market

in Singapore becoming more oil & gas

related and it was gradually moving from

the traditional realm of electronics.

The strong market for oil tool production

in Singapore is an exciting prospect for the

company and Mr Price expressed hopes

to expand the oil tool market and help

customers develop processes for deep hole

drilling when required. In conclusion, he

said: “We are excited about helping people

be more competitive.”

Improving Efficiency Through Measurements

On display for the first time in Singapore is

Vici Vision’s MTL 300, an optical measuring

machine for cylindrical parts like shafts. The

machine is dedicated to the measurements

of parts directly on the shop floor, said

Erick Fantini, sales manager of Vici & C.

Measuring par ts directly on the

shop floor is a concept of measurement

designed to optimise the production. This

philosophy, as aptly pointed out by Mr

Fantini, should not only focus on providing

quality inspection, but also improve

efficiency in production.

He added that the machine is capable

of inspecting roundness, run-out and

cylindricity in addition to other static

or geometric measurements. The data

collected can later be used to set up a CNC

lathe. The value in doing so, according to

Mr Fantini, is to prevent rejections and

downtimes during production. This is a

pertinent point as far as he is concerned,

because he noticed a trend of producing

cheaper parts with higher quality.

In terms of reliability, the machine

has a step-master to constantly correct

variations. The mechanical construction of

the machine, according to Mr Fantini, also

adds to its stability. He said: “The machine

has one axis movement, so basically you

don’t get the same trouble that you have

while on the CMM. In addition, we have

anti-vibrating feet and the exposure time

of the camera is quite fast.”

Lenox Ready To Contest The Bandsaw Market

New at MTA2013 is the Contestor XL

bi-metal band saw blade from Lenox.

Featuring a high-speed steel on the edge tip

according to Vincent Chai, sales manager

(Bandsaw) Malaysia, Singapore & Vietnam

of Lenox, the blade is said to be capable

of longer life.

“This bimetal bandsaw would be

different from the M42 but equivalent to the

M51 (grade). It is also hardened, has higher

wear resistance and less susceptible to

fatigue stress,” he said.

Designed for large and difficult-to-cut

metals like titanium and Inconel, the blade

mostly targets the oil & gas industry. It is

also suitable for the aerospace industry

where again, the difficult-to-cut metals

come into play.

Mr Chai also revealed that the company

carried out some tests and the blade

fared well. “There is more than 30 percent

increase in tool life when comparing with our

top bi-metal series,” he said. Finally, he said

the Contestor XL will be available around

the world in the beginning of June this year.

Satisfied Exhibitor

Mr Chai is one of many exhibitors that have

commented on the quality of leads they

received during the show.

“I like MTA Singapore, most of the people

that come in here are looking for specific

things that are related to metal. Some 80

percent of visitors actually need something

from here. In Singapore (MTA2013), I can find

people from India, Indonesia, Middle East

and Europe,” he said.

Mr Chai’s glowing assessment of the

show can probably be attributed to the

number of enquiries he received, which

stood at an excess of 50 (on the third

day of the event). He also remarked that

most enquiries were made by existing and

potential users, and he is confident that his

distributor is capable of providing a one stop

solution for his customers in Singapore.

Manufacturing Expo 2013 will be back at BITEC, Bangkok from June 20 – 23,

2013. According to the organiser, manufacturing technologies from 1,500 brands and 22 countries will be presented at the show.

T h e A S E A N E c o n o m i c Community (AEC) is fast becoming a reality. ASEAN countries are adapting their laws and regulations for seamless integration and more than 70 percent of this work is already done.

The world recognises AEC as a single market and the economic power of over 600 million people in one of the fastest developing region of the world. To this end, manufacturers in ASEAN are gearing up their plant processes to make their technologies world class and competitive, in order to emerge as regional leaders.

Thailand has concentrated its energies into developing the automotive industry and the country is fast approaching the goal of becoming the world’s eighth


largest auto makers when annual vehicle production reaches 2.5 million vehicles. Auto production in 2013 is already predicted to reach 2.4 million vehicles and major brands are expanding production, to meet growing domestic and export demands.

Various needs of Thailand’s and the region’s automotive industry like metal, non-metal parts, rubber parts, plastics parts, assembly technologies, electronics and others, are met by Manufacturing Expo 2013. This show brings the latest technologies to visitors who are ASEAN’s leading manufacturers, and subcontractors of components and parts for the automotive and electronics industries.

MTA Vietnam 2013 will be held from July 2 – 5, 2013 at the Saigon Exhibition &

Convention Center (SECC) in Ho Chi Minh City. Into its 11th edition, the event has proven to be the Vietnamese manufacturers’ procurement ground of choice, as manufacturers from Vietnam will be presented with the latest technologies and services in precision engineering, machine t o o l s a n d m e t a l w o r k i n g presently available in the global marketplace.

Since its inception in 2005, the show has seen increasing and continued support from local and international manufacturers. Some of the key international brands are: Agie Charmilles, Amada, Bystronic, Carl Zeiss, Chin Fong, DMG/Mori Seki, Flow, Hexagon Metrology, Haas, Hurco, HwaCheon, Iscar, Mazak, Mitsubishi Electric, Mitutoyo, MST, OKK, Okamoto, Sodick, Studer and Trumpf.

International InterestThe event has also received strong support from international trade bodies and government agencies, leading to an increase in size of group pavilions this year.

To date, there are 11 group pavilions from eight countries and regions. They include Germany, I ta ly, Japan, South Korea , Singapore, Taiwan, Thailand and the UK.

Vietnam Manufacturing ClimateA t te n d a n ce a t t h e e v e n t has been steadily increasing,


reaching a record number 10,000 attendees in 2012. The sight of group delegations arriving in droves from notable companies are testament to the bright and promising outlook of Vietnam’s manufacturing landscape.

A rosy macro - economic picture of single digit inflation, lower interest rates and a strong and stable local currency has resulted in imports growing by 10 percent and exports rising by 24 percent year-on-year in the first two months of 2013.

The Vietnamese processing and manufacturing industry has also remained the most attractive for foreign investors. Foreign Direct Investment (FDI) into Vietnam’s manufacturing and processing sector has been rising in recent years, the percentage of FDI dedicated to projects in manufacturing and processing increased from 40 percent of the country’s total pledged FDI in 2010

to 48.5 percent in 2011 and 69.9 percent in 2012.

The manufacturing industry in Vietnam has seen a shift from low value verticals such as textiles to more high-tech, high value manufacturing. The year 2012 saw international brand names such as Fuji Xerox, Samsung, Nokia and Intel investing more into their manufacturing facilities in Vietnam.

In addition, the world largest mobile phone vibration motor manufacturer Nidec Seimitsu Corporation from Japan has built its first factory in Vietnam which was completed at the end of 2012.

Esco Tool: Pipe Beveling Tools

A ful l l ine of pipe beveling welding end prep tools that combine rigidity with a wedge-lock cutter head and blades that produce a thick chip without cutting oils is available from Esco Tool.

Esco Millhog Pipe Beveling Tools pull a thick chip without cutting oils to promote weld integrity and faster fit-up by providing a precise end prep that is superior to hand grinding. Producing any angle of prep from 37.5 to 10 degree and compound bevels, these tools incorporate the EscoLock wedge-lock cutter head and proprietary blade featuring a radical chip breaker which gets under the material and directs heat away from the surface.

TaeguTec: Wider Cutting Range

Walter: Improving Tool Life With Colour

TaeguTec has expanded the Chase2Hepta family series of cutters with a right-handed, neutral and wiper inserts which will cover a range of applications.

The sharp –ML geometries of the XNMU 0906 ANTR-ML insert with a full length helical cutting edge is suitable for milling steel under unstable machining conditions such as weak fixtures and clamping, long tool overhang and work pieces with weak cross-sections.

The neutral insert, XNHU 0906 ANTN-ML, is suitable for cast iron machining in unstable machining conditions. For those looking for good surface finishing in milling applications, the company also introduced the XNHU 0906 ANTN-W wiper insert which has two right-handed and two left-handed cutting edges.

Color Select, a cutting tool material from Walter, combines optimal service characteristics with simple wear detection. Field tests have shown that tool life has, on average, been increased by almost 100 percent.

The improved microhardness and its toughness add to the cutting tool material’s increased performance. At the same time, the coating thickness is thinner than on the previous cutting tool material.

Another feature is that the indexable inserts are coloured in standard ISO colours, which gave the cutting tool material its name. This means they are recognisable and the risk of a mix-up is reduced.



Siemens PLM: Reducing Airframe Design Processing Time

The Syncrofit 13 software by Siemens PLM now has a fastener layout and part sizing functionality. It helps airframe engineers reduce the time to generate fastener patterns, perform initial part sizing, validate designs and adapt to subsequent design changes by as much as 40 percent.

This version eliminates the need for manufacturing engineers to manually verify if fasteners in an airframe structure are properly consumed according to plan and that the assembly meets design requirements. Another pertinent point of the software sees the expanded integration with Siemens’ Teamcenter portfolio.

Sutton Tools: Cutting In Harmony

S u t to n To o l s h a s developed the VA-Harmony Endmill. It has been engineered

specifically for milling sta in le ss stee ls a nd

super alloys — such as austenitic grades 304 and

316, duplex grades, as well as inconels 718 and 725.

The EndMill is aimed at companies producing equipment for the oil & gas, aerospace, food & beverage, medical and marine industries.

According to the manufacturer, the Endmills are available in diameters from 6 to 20 mm. It features an ultra-fine micro-grade carbide base material, which offers the wear resistance for high-performance milling applications.

The product also employs a Balzers Oerlikon Helica multi-layer coating, designed specifically to work with the characteristics of carbide tools.
