Page 11: Foo Jin Hoe, PhD. jinhoe@fkm.utm.my C23-408 +6(07)-5534703 AUTOMATION IN MANUFACTURING

Fixed-position layout : Workers and processing equipment are brought to the product, rather than moving the product to the equipment .This type of layout referred to as fixed-position layout.

Process layout: The individual parts that comprise these large products are often made in factories that have a process layout.

Page 12: Foo Jin Hoe, PhD. jinhoe@fkm.utm.my C23-408 +6(07)-5534703 AUTOMATION IN MANUFACTURING

Cellular layout: The term cellular manufacturing often associated with this type of production. Each cell is designed to produce a limited variety of part configurations. That is the cell specializes in the production of a given set of similar parts or products according to the principles of group technology.

Product layout: The collection of stations is designed specifically for the product to maximize efficiency.

Page 16: Foo Jin Hoe, PhD. jinhoe@fkm.utm.my C23-408 +6(07)-5534703 AUTOMATION IN MANUFACTURING

Understand the existing process

The first step in the USA approach is to comprehend the current process in all of its details.

* What are the inputs? What are the outputs ?

* What exactly happens to the work unit between input and

output?

* What is the function of process?

* How does it add value to the product?

* What are the upstream and downstream operations in the product sequence, and can they be combined with the process under consideration?.

Page 17: Foo Jin Hoe, PhD. jinhoe@fkm.utm.my C23-408 +6(07)-5534703 AUTOMATION IN MANUFACTURING

Simplify the process

*Once the existing process is understood, then the search can began for ways to simplify. This often involves a checklist of questions about the existing process.

Unnecessary steps can be eliminated without detracting from the function.

Page 18: Foo Jin Hoe, PhD. jinhoe@fkm.utm.my C23-408 +6(07)-5534703 AUTOMATION IN MANUFACTURING

Automate the process

*Once the process has been reduced to its simplest form then automation considered. The possible form of automation include those listed in the ten strategies.

Automation seems a feasible solution to improving productivity, quality, or other measure of performance then the following ten strategies for these improvements discussed.

1. Specialization of operations: The first strategy involves the use of special-purpose equipment designed to perform one operation with the greatest possible efficiency. This is analogous to the concept of labor specialization. Which is employed to improve labor productivity.

2. Combined operations: Production occurs as a sequence of operations. Complex parts may require dozens, or even hundreds, of processing steps. The strategy of combined operations involves reducing the number of distinct production machines or work stations.

Ten Strategies for Automation and Production Systems

Page 20: Foo Jin Hoe, PhD. jinhoe@fkm.utm.my C23-408 +6(07)-5534703 AUTOMATION IN MANUFACTURING

3. Simultaneous operations: A logical extension of the combined operations strategy is to simultaneously perform the operations that are combined at one work-stations. In effect two or more processing (assembly) operations are being performed simultaneously on the same work part.

4. Integration of operations: Another strategy is to link several work stations together into a single mechanism, using automated work handling devices to transfer parts between stations.

5. Increased flexibility: This strategy attempts to achieve maximum utilization of equipment for job shop and medium value situations by using the same equipment for a variety of parts or products.

6. Improved material handling and storage: A great opportunity for reducing non-productive time exists in the use of automated material handling and storage systems.

Page 21: Foo Jin Hoe, PhD. jinhoe@fkm.utm.my C23-408 +6(07)-5534703 AUTOMATION IN MANUFACTURING

7. On-line inspection: Inspection for quality of work is traditionally performed after the process is completed. This means that any poor-quality product has already been produced by the time it is inspected.

8. Process control and optimization: Manual control to automated control by optimization we can give the best parameters. Then the individual process can be reduced.

9. Plant operation control: Those which are not related fabrication process, each division specify automate. Business functions, product design.

10. Computer- integrated manufacturing: Input from market delivery to the final customer every operation is integrated to the computer. Business functions, product design etc…..

Automation Migration strategy

Owing the competitive pressures in the marketplace, often needs to introduce a new product in the shortest possible time. A typical automated strategy is shown.

Phase 1: Manual production using single station manned cells operating independently.

Phase 2: Automated production using single station automated cells operating independently.

Phase 3: Automated integrated production using a multi station automated system with serial operations and automated transfer of work units between stations.

Manual Assembly LinesManual Assembly Lines

-Most manufactured consumer products are assembled. Each product consists of multiple components joined together by various assembly processes. These kinds of products usually made on a manual assembly Line. Factors favoring the use of manual assembly lines include the following.

-Most manufactured consumer products are assembled. Each product consists of multiple components joined together by various assembly processes. These kinds of products usually made on a manual assembly Line. Factors favoring the use of manual assembly lines include the following.

Demand for the product is high or medium . The products made on the line are identical or similar The total work required to assemble the product can be divided into small work elements. It is technologically impossible or economically infeasible to automate the assembly operations.

Manual Assembly Lines are so productive compared with alternative methods.

Specialization of labor: Called “Division of labor”, this principle asserts that when a large job is divided into small tasks and each task is assigned to one worker, the worker becomes a specialist.

Interchangeable parts: In which each component is manufactured to sufficiently close tolerances that any part of a certain type can be selected for assembly with its mating component. Without interchangeable parts

assembly would require filing and fitting of mating components.

Page 28: Foo Jin Hoe, PhD. jinhoe@fkm.utm.my C23-408 +6(07)-5534703 AUTOMATION IN MANUFACTURING

Work principle, in material handling, which provides that each work unit flows smoothly through the production line , traveling minimum distances between stations.

Line pacing: Workers on an assembly line are usually required to complete their assigned tasks on each product unit within a certain cycle time, which paces the line to maintain a specified production rate.

Fundamentals of Manual Assembly Lines

A manual assembly line is a production line that consists of Sequence of workstations where assembly tasks are performed by human workers. Products are assembled as they move along the line. At each station a portion of the total work is performed on each unit. Base parts onto the beginning of the line at regular intervals. Each base part travels through successive stations and workers and components through progressively build the product.

Assembly WorkstationsAssembly Workstations

A workstation on a manual assembly line is a designated location alongThe workflow path at which one or more work elements are performedBy one or more workers. The work elements represent small portions of the total work that must be accomplish to assemble the product.

Some Workstations are designed for workers to stand, while other allow the workers to sit. When the workers stand, they can move about the station Area to perform their assigned task. Example like cars, trucks…… The typical case is when the product is move by a conveyor at constantVelocity through the station. The worker begins the assembly task near the upstream side of the station an moves along with the work until the task is completed, The walks back to the next work unit an repeats the cycle.

M= w n

For a manual assembly line, the manning level of work station i=1,2…nAnd n= number of workstations on the line. The generic case is one worker Mi=1. In cases where the product is large such as car or a truck, multiple workers are often assigned one station, so that Mi>1.

Multiple manning conserves valuable floor space in the factory and reduces line length and throughput time because fewer work stations are required. The average manning level of a manual assembly line is simply the total number of workers on the line divided by the number of stations. That is

Manual assembly lines often include more workers thanthose assigned to stations, so that M is not a simple average of Mi values. These additional workers called utility workers, are not assigned to specific workstations; instead they are responsible for functions such as 1) Helping workers who fall behind, 2) relieving workers for personal breaks, and 3) Maintenance and repair duties. Including the worker count we have M = wu+∑ wi (where i= 1 to n) n

Work Transport SystemsWork Transport Systems

There are two basic ways to accomplish the movement of work units along a manual assembly line 1) manually or 2) by a mechanized system.Both methods provide the fixed routing (all work units proceed through the same sequence of stations) that is characteristic of production lines.

Manual Methods of Work Transport: In manual work transport, the units of product are passed from station-to-station by hand. Two problems result from this mode of operation: Starving and blocking.Starving is the situation in which the assembly operator has completed the assigned task on the current work unit, but the next unit has not yet arrived at the station. The worker is starved for the work.

When a station is blocked, it means that the operator has competed the assigned task on the current work unit but cannot pass the unit to the downstream station because that worker is not yet ready to receive it. The operator is therefore blocked from working. To mitigate the effects of these problems, storage buffers are sometimes used between stations. In some cases, the work units made at each station are collected in batches and then moved to the next station. In other cases work units are moved individually along a flat table or un powered conveyor.

Material handling is defined by the Material Handling Industry of America as “ the movement, storage, protection and control of materials throughout the manufacturing and distribution process including their consumption and disposal”. The handling of materials must be performed safely, efficiently, at low cost, in a timely manner, accurately and without damage to the materials.

( the right materials in the right quantities to the right locations)

This cost of material handling is a significant portion of total production cost, estimates averaging around 20 – 25 % of total manufacturing labor cost in the united states. The proportion may varies , depending on the type of production and degree of automation in the material handling function.

Some material handling devices are

- pallet shuttles in NC machining centers - Conveyors in manual assembly lines

- transfer mechanisms in automated transfer lines

- parts feeding devices in automated assembly

Material handling equipment is available commercially

1. Transport equipment

2. Storage systems

3. Unitizing equipment

4. Identification and tracking systems

Material Transport EquipmentMaterial Transport Equipment

Material transport includes equipment that is used to move

materials inside a factory, ware house, or other facility. This

equipment can be divided into the following five categories

1. Industrial trucks: Industrial trucks divided into two types

powered and non-powered.

Non-powered trucks are platforms or containers with wheels

that are pushed or pulled by human workers to move the

materials.

Powered industrial trucks are steered by human workers.

They provide mechanized movement of materials.

Page 44: Foo Jin Hoe, PhD. jinhoe@fkm.utm.my C23-408 +6(07)-5534703 AUTOMATION IN MANUFACTURING

2. Automated guided vehicles (AGVs): AGVs are battery –powered, automatically steered vehicles that follow defined pathways in the floor. AGVs are used to move unit loads between load and unload stations in the facility. Routing variations are possible ( Different loads move between different stations)

3. Monorails and other rail guided vehicles: These are self-propelled vehicles that ride on a fixed rail system . The vehicles operate independently and are usually driven by electric motors that pick up power from an electrified rail.

Routing variations are possible

4. Conveyors: Conveyors constitute a large family of material

Transport equipment that are designed to move materials over fixed paths, generally in large volumes.

Powered conveyors roller, belt and tow-line and non-powered by human workers

Page 45: Foo Jin Hoe, PhD. jinhoe@fkm.utm.my C23-408 +6(07)-5534703 AUTOMATION IN MANUFACTURING

5. Cranes and hoists: These are handling devices for lifting , lowering, and transporting materials, often as very heavy loads. Hoists accomplish vertical lifting.

Both manually operated and powered types are available. Cranes provide horizontal travel and generally include hoists.

Storage systems: It is generally desirable to reduce the storage of materials in manufacturing, it seems unavoidable that raw materials and work-in process will spend sometime being stored, even if only temporarily. And finished products are likely to spend sometime in a ware house or distribution center before being delivered to the final customer.Storage methods and equipment can be classified as followsa) Bulk storage: It consists of simply storing materials in an open floor area, generally in pallets or containers. It requires little or no storage equipmentb) rack systems: These are structural frames designed to stack unit loads vertically, thus increasing the vertical storage efficiency compared to bulk storage

c) Shelving and bins: Steel shelving comes in standard widths, depths, and heights to serve a variety of storage requirements. Shelves can include bins, which are containers for loose items.

Page 48: Foo Jin Hoe, PhD. jinhoe@fkm.utm.my C23-408 +6(07)-5534703 AUTOMATION IN MANUFACTURING

d) Drawer storage: This storage medium is more costly than shelves, but is more convenient. Finding items stored in shelves can be difficult if the shelf level is too high or too low or too deep. It is generally used for tools, hardware and other small items.

e) Automated storage systems: Automated and semi automated systems are available to deposit and withdraw items into and from the storage compartments.

There are two basic types: automated storage or retrieval systems: consists of rack and shelf systems 2) Carousel systems that rotate storage bins past a stationary load or unload station.

Page 49: Foo Jin Hoe, PhD. jinhoe@fkm.utm.my C23-408 +6(07)-5534703 AUTOMATION IN MANUFACTURING

Unitizing equipment:

It refers to 1) containers used to hold individual items during handling 2) equipment used to load and package the containers. Containers include pallets, boxes, baskets, barrels, and drums.

Identification and tracking systems: Material handling must include a means of keeping track of the materials being moved or stored. We assign label to the item.

The 10 Principles in Material HandlingThe 10 Principles in Material Handling

The 10 principles of material handling are explained below. Implementing these principles will result in safer operating conditions,

lower costs, and better utilization and performance of material handling systems.

The unit load principles stands as one of the most important and widely applied principle in material handling. In material handling, a unit load is Simply the mass that is to be moved or otherwise handled at one time.There are good reasons for using unit loads in material handling1) Multiple items can be handled simultaneously2) The required number of trips is reduced3) Loading and unloading times are reduced4) Product damage is decreased. These reasons result in lower cost and higher operating efficiency.

Principle 1. PLANNING PRINCIPLE: All the material handling shouldbe the result of a deliberate plan where the needs, performance objectivesAnd functional specification of the proposed methods are completely Defined at the outset.

Principle 2. STANDARDIZATION PRINCIPLE: Material handling Methods, equipment, controls, and software should be standardized .It means less variety and customization in the methods and equipment employed.

Principle 3. WORK PRINCIPLE: Material handling work should be minimized without sacrificing productivity or the level of service required of the operationSimplifying the processes by reducing, combining, shortening, or eliminating unnecessary steps will reduce work.
