What‘s up
CogniTens launched a European demon-
stration center for its fully automated 3D
measurement system, the OptiCell. The demo
system is operational at the Hexagon Metrol-
ogy Precision Center in Turin, Italy.
Hexagon Metrology has finalised a signifi-
cant collaboration agreement with GF
AgieCharmilles. Under the terms of the
commercial arrangement, Hexagon Metrology
becomes the preferred measurement partner
for the Swiss multinational. GF AgieC-
harmilles will now specify Hexagon Metrology
co-ordinate measuring machines for all its 3D
pre-setting and measurement applications.
Hexagon Metrology is offering attractive and
flexible rental programmes for all portable
product lines. Improving quality and perform-
ance has never been this easy.

Three new measurement systems based on
the Leica Absolute Tracker were recently
delivered to the Volkswagen facility in Wolfs-
burg, Germany. Furthermore, Volkswagen
in Kaluga, Russia now uses a Leica T-Probe
system.
Hexagon Metrology Poland participated in a
project of the Institute of Forensic Research
in Cracow with the objective of scanning a
human skull and obtaining a 3D model that
identifies characteristic elements. The equip-
ment used was a ROMER Sigma arm with the
ROMER scanning probe G-Scan and the soft-
ware PC-DMIS Reshaper. The scanning took
30 minutes and included 2,000,000 points.
A high quality model was the result – a big
success for both the Institute of Forensic
Research and Hexagon Metrology.
New at Alstom Power in Poland:
A Leica Absolute Tracker with a Leica T-Probe
is applied for quality control and alignment
tasks.
Specifications of the Leitz Micra – the CMM
for small precision parts – have been im-
proved: The temperature range has been en-
hanced to a range of 18 - 22 °C. The maximum
stylus weight has been increased to 30 g.
This way all relevant star styli configurations
can be used with the Leitz Micra. Tests with
small probes (up to 0.3 mm ball tip diameter)
demonstrated very good performance for
applications in the watch industry and for the
measurement of other small precision parts.
Eurocopter Donauwörth, Germany
upgraded their systems with a Leica
T-Probe for faster inspection proc-
esses.
German car manufacturer Audi has acquired a complete Leica
Geosystems Laser Tracker System for fully automated meas-
urement processes including a Leica T-Scan and a Leica T-Mac
with a Touch Trigger Probe.

Portrait
A man for all situations: Lothar Schäfer, Applications Engineer at Hexagon Metrology
Ready for the call
If there is a burning issue at a customer‘s
premises, e.g. something is interfering with
the smooth operation of his PC-DMIS measure-
ment software, the applications engineer
knows what he has to do. “My work involves
me everyday with ultra-accurate Leitz coor-
dinate measuring machines and I have been
providing worldwide support for PC-DMIS
software for over eleven years,” says Schäfer.
“Customers call me here in Wetzlar when they
need support. We then place the software
problem under the magnifying glass.” Running
the Hotline is just one aspect of his job. Prod-
uct presentations, special programming for
customers, on-site software support, training
courses, assisting in the development of new
products and providing customers with advice
at trade fairs prevent Lothar Schäfer from ever
becoming bored.
A knack for technology – and people
Originally from Germany‘s Rhineland-Pfalz,
Schäfer relies on his technical know-how in
particular to perform his duties. “Being able to
understand technology is simply an essential
requirement of the job. I studied electrical
engineering but, like all my colleagues, I
entered a career different from my educational
background and qualifications. Our knowledge
is based for a large part on learning-on-the-
job. After a while my “toolbox” became packed
as I gained experience in metrology,“ says
Schäfer.
The “toolbox” has become so full that Schäfer
is now a certified trainer working with AUKOM
(Ausbildung Koordinatenmesstechnik e.V.)
to pass on the skills of his trade to budding
metrology engineers. It stands to reason that
being a good judge of people is indispensable
in this role. The needs of every participant
must be accurately determined by Schäfer
during his training sessions – whether they
involve customers, colleagues from other
branches of the company or novices to the
field of metrology.
A winning team
With all the work and the challenges that
the job brings, Lothar Schäfer finds nothing
runs smoothly without a harmonious working
atmosphere. “We are a strong team provid-
ing software support for highly accurate
Leitz CMMs. If I‘m making no headway on a
particular job, I can always find someone here
who can help me out!” And to ensure the good
relationship between colleagues continues in
this positive mode, they shall be going on a
communal hike together again this year. This
fruitful interaction among colleagues can only
be to their benefit – and ultimately to the ben-
efit of the quality of the software support.
What would you like to be when you grow up? Put this question to any seven-year-old and it
is 90% certain that the answer would be: a fire-fighter! Lothar Schäfer lives out this dream
in a special way. He provides the same service as the fire brigade: an applications engineer
is always there when help is needed.

Cover Story
GLOBAL CMMs from the brand DEA
are flexible and exact. But how are
such measuring machines produced?
measureup joined Production Manager
Bartolino Margiotta in the search for
clues in Northwest Italy to disclose
this secret.
We met Bartolino Margiotta in the produc-
tion hall of Hexagon Metrology S.p.A. in
Grugliasco, just a few kilometres west of
Turin. Bartolino has been working for Hexagon
Metrology for 28 years and thus is an expert
in his field. Under his supervision, workers
in production make sure that the countless
mosaic pieces involved add up to a complete
picture: such as for instance, the GLOBAL
coordinate measuring machine from the brand
DEA.
The answer can be found in the name
The name GLOBAL already leads us to assume
what happens at the very beginning of the
production process: some of the components
are bought from various producing suppliers
distributed all over the world. The parts don‘t
only come from numerous corners of this
planet; they are also delivered to many places
as well. Hexagon Metrology has production
locations in USA, China, Brazil and Italy in
the field of stationary coordinate measuring
machines. At these locations, components are
installed in the various measuring machines
of the group. This keeps costs down since
large amounts can be ordered. Lorries under
contract from Italian companies however still
drive through the factory gates in Grugliasco
as small components of the DEA GLOBAL
coordinate measuring machines are obtained
through local partners.
“Made in Italy“ is likewise at the core of the
various measuring machines produced. They
all take shape in Moncalieri – just a stone‘s
throw away from Grugliasco. Bartolino Mar-
giotta explains: “In Moncalieri, our affiliate
company Precision Machining finishes the
most important parts of the CMMs. Among
these are the beams and rams for example.
These have a direct impact on the perform-
ance of the measuring machine. From Mon-
calieri, these components reach not only us,
but also the other CMM production facilities of
Hexagon Metrology.“
Clearly calculated scheduling
The production planner‘s foresight is needed
before the assembler can start with his work.
They organise the material purchasing for
the small DEA GLOBAL CMMs by means of
prognoses. Keen awareness is necessary for
future demands. Production stock should not
be too high, in order to avoid high storage
costs, or too low, in order to keep production
moving steadily. The team manages the “just-
in-time” loading of the line buffers in order to
have the right materials at the right time in the
assembly areas. The larger components of the
larger GLOBALs are only made to order.
Components differ slightly in material, form
and origination according to the model. For
instance, the dark granite used for smaller
GLOBAL measuring equipment has already
travelled many miles before its arrival. It was
taken out of stone quarries in Asia. The lighter
granite used in the larger GLOBAL CMMs
originates from Italy’s neighbouring country
France. The reason for the different means
of obtaining these materials is that Hexagon
Metrology is dependent on short delivery

times with larger CMMs, since these are only produced to order.
A delivery of granite from Asia would, in this case, take way too
much time.
The beams also arrive in Grugliasco in various shapes. Further-
more, rams are made from varying materials dependant on
the model for which they will be used; these include very stiff
ceramic and lightweight aluminium.
An ear to the market with local manufacturing
Purchasing is done worldwide thus Hexagon Metrology profits
from the advantages of a global-oriented procurement strategy.
Assembly takes place at a local level and within close proximity
to customers – whether in Italy, USA, China or at the Brazil loca-
tion. Hexagon Metrology can then be fast and flexible to meet
customer demands.
In Piedmont, all three models of the GLOBAL family come
together as one large ensemble: GLOBAL Classic, Performance
und Advantage CMMs. The production area is divided into three
separate islands and each one is designated for different sized
CMMs, from the smallest, to the medium sized and finally to the
largest GLOBALs. The components and tools are always within
easy reach since the rule of thumb is: materials are at your
fingertips, always within five easy steps.
Cover Story
Production Manager Margiotta reveals to us the basics of
GLOBAL assembly: “To begin with, the legs and beams are joined
together to build the portal. Also, our assembler attaches the
granite surface plate onto the steel base. This machine base
is equipped with the scales, the transmission system and with
some types, a temperature sensor. Subassemblies, such as
counterweights for the Z-ram and the X-carriage, speed up the
assembly process. Finally, our workers attach the X-carriage to
the portal. The portal is then connected to the granite table. The
CMMs can now also be completed with a protective enclosure for
example, depending on the customer needs.“
CMMs put to the test
If all components are perfectly integrated then the GLOBAL tour
continues a few meters further down to a temperature stable
room. “We construct the measuring system in the calibration
room exactly as it will stand afterwards by the customer; this
means we add the customer‘s required controls, the subsequent
computer and the required measurement heads”, says Bartolino
Margiotta. “In this way, we can be sure that the customer can
rely on our exact specifications and receive the accuracy needed
for his measuring task. Before we calibrate the CMM, we let the
machine run all night so that we can be sure everything‘s in
working order with it. After the calibration, the GLOBAL CMMs
are tested for the ISO standards 10360 with the help of a gauge.“

At the base of the mountain: Piedmont
Piedmont is located between the border of
Switzerland and France, and borders the Italian
provinces of Liguria, Emilia Romagna and Lom-
bardy as well as the region of the Aosta Valley.
Four million people reside here. Waterfalls,
lakes, vineyards and breathtaking serpentines
characterise the landscape. The picturesque
Lake Maggiore and Lake Orta are well known
and long established tourist attractions.
However the capital of Piedmont Turin also
attracts visitors with its Baroque architecture.
An absolute must after a visit to one of Turin‘s
many museums is trying a cup of Bicerin –
made from a mixture of coffee, hot chocolate,
milk and cream. Not only sweet treats can
be found in Piedmont, the grapes from the
famous Barolo, Barbera and Barbaresco thrive
magnificently in Piedmont. Truffle fans will love
Alba and many award winning delicacies can
be found in local cheese dairies and shops.
1 The legs… 2 …plus a beam from Montcalieri…
3 …make up the portal. The configuration with triangular beams
optimises the stiff-to-mass ratio. 4 The GLOBAL CMMs can be
delivered with an optional climatic enclosure. This protects the
measuring machines not only from dirt but also guarantees a
consistent temperature. 5 Granite is well known for its temper-
ature stability. It is manufactured from one piece. Patented dove-
tail guideways are incorporated into the granite. 6 Assembler
Pietro Celeste installs the ram of a GLOBAL, the core of these
CMMs. Depending on the model, the rams consist of aluminium
alloy, alumina materials or ceramic. 7 Each employee is
obliged to enter the necessary information in the documents, for
example the time needed for every assembly step. Afterwards,
the data is entered in the SIQ quality management system. In
the end, a complete documentation of the production process
exists. 8 Another part of the inner workings of a GLOBAL are
the counterweights – cylinders that compensate for the weight
of the Z-rams. 9 The GLOBALs leave the calibration room
equipped with special mountings for safe transport. There‘s only
the protective vacuum packaging missing and the wooden box,
and they‘re ready to go – by lorry, train or ship. 10 Whether a
small or large GLOBAL CMM – the production process follows
the same pattern. 11 Production Manager Bartolino Margiotta
shows us a small but important part of the GLOBAL CMMs: the
air bearings. They run later on the precisely finished dovetail
guideways and assure smooth movement of the portal.
12 The thermometer in the calibration room shows a constant
21° Celsius. Here there‘s room for up to 20 machines.
Cover Story
Genetic makeup of each GLOBAL: the SIQ
If the GLOBAL mastered all the tests then the shipping docu-
ments can be prepared using the SIQ system. This quality man-
agement system developed by Hexagon Metrology has a similar
function to DNA in a person‘s body: all information concerning
the coordinate measuring machine is saved in this system.
Which were the specific servo parameters? Which measurements
were conducted during calibration of the machine? And when did
these tests take place? SIQ knows the answer. It supports Hexa-
gon Metrology throughout production to keep quality high.
Transport is the final stage of the production process and begins
already on the way from the calibration room to the shipping
department. The GLOBAL CMM is made ready for the customer
demands in the climatic chamber. Workers install special
mountings between the measurement table and the portal which
prevent machines from being damaged along the way. In the
shipping department the workers carefully vacuum pack the
valuable freight, to protect the CMM from humidity. After being
covered, the machine is then placed in a wooden box. Along with
all the shipping and quality documents from SIQ, the GLOBALs
are finally ready for their trip and bring along with them high tech
from Piedmont.

PC-DMIS Reshaper – perfect for rapid handling
of point cloud files for high quality 3D meshes
at an affordable price.PC-DMIS Reshaper – the 3D scanner softwarePC-DMIS Reshaper is perfectly
suited for working with very big
point clouds. The more the point
number increases, the more the
difference compared to other
software is evident. The main
difference between PC-DMIS Re-
shaper and other software is the
increased speed: you can thus
handle millions of points without
any limit, and create 3D meshes
in few seconds.
measureup shows some of
the most important software
features.
“Inspection and contour control”
provides the possibility to compare two
polylines or curves with the same pro-
cedures as for 3D surfaces comparison.
Like inspection and 3D surfaces control,
you can create color mappings and edit
labels on particular points and export
or print customized inspection reports.
PC-DMIS Reshaper is used by many
customers as 3D inspection software.
PC-DMIS Re shaper software implements
all features you need to perform 3D
inspection and dramatically reduces the
time to make 3D inspection colour map-
ping and reports.
Inspection features are not a separate
product or module like in many other 3D
inspection software or compare to CAD
software. Everything is included in PC-
DMIS Reshaper without any additional
cost.
With PC-DMIS Reshaper, users create
point clouds to measure geometric
elements like planes, cylinders, circles,
spheres etc. You can calculate or extract
features directly from point clouds. Other
than that, the inspection software gives
you information on standard deviation
(average error), tolerance and distri-
bution. You can inspect or control a
particular geometry or hole. Geometrical
shapes can be used in different ways,
e.g. to export inside a CAD system
using IGES and DXF interfaces. These
shapes can also be used for geometrical
constructions such as projections and
intersections and to measure distances
or a surface flatness.
PC-DMIS Reshaper supports the handling
of a great number of points, finding
the ideal solution for your problem and
answers questions like: What is the
maximum or average error?
Could there be a better solution rejecting
10% or 20% of the points? Which point
should be kept or rejected?
The computation is immediate; the pre-
view button is the only click that has to
be made. High level algorithms dramati-
cally increase the point clouds process-
ing speed and the model accuracy.

Ogihara eliminates hundreds of inspection hours with OptiCell by CogniTensOgihara America Corporation is a sub-
sidiary of the Japanese Ogihara Corpo-
ration, one of the largest independent
automotive die manufacturers in the
world today. Based on Ogihara’s re-
quirements for the highest level of op-
erational flexibility possible CogniTens
together with its partner Inspection
Air Gauge designed a fully automated
and standardized OptiCell footprint for
providing rapid dimensional results for
closure sub-assemblies originating from
multiple vehicle programs.
The standardized OptiCell configuration
offered tight integrations of sophisticated
robotics technology, operator-machine
interface as well as cell automation and
control devices such as rotary tables and
flexible holding fixtures. This integrated
approach accommodates the maximum
number of parts and assemblies, while
minimizing the costs associated with mak-
ing changes and providing maintenance.
Additionally, it allowed parts and as-
semblies to be easily adapted to specific
GD&T requirements.
Today, Ogihara’s OptiCell systems pro-
vide production associates with instant
line side data required to make compre-
hensive functional build adjustments as
needed. The ease of use, rich metrology
data set and location on the plant floor
turned the Opti-Cell into a welcomed
asset for the Ogihara launch and pro-
duction teams. “Implementing OptiCell
is a major step forward towards realizing
Ogihara’s vision of moving from tradi-
tional gauging systems to highly flexible
and integrated measurement systems”,
said Steve Peca, Executive Manager for
Quality Systems at Ogihara America.

Service & Support
If your business provides precise industrial
measurement solutions, your reputation can
often depend on the reliability and accuracy of
measuring instruments. Industrial theodolites
and laser stations from Leica Geosystems have
proven accuracy and reliability whether fresh
from the factory or after many years of use.
However, as with all mechanical and optical
hardware, continuous high performance and
reliability is enhanced through general care and
periodic maintenance.
15
01/09measureup
Precision is the byword on a busy industrial park at the edge of the
Czech capital, the location of the new European Service Centre for in-
dustrial theodolites and total stations from Leica Geosystems, a centre
to provide a portfolio of dedicated technical services. Factory trained
specialist service engineers have many years of experience with han-
dling servicing and repairs for these instruments. Their skills extend to
every lens, gearwheel and housing seal that has to perform in some-
times extreme conditions. Theodolites, for example, that do not shelter
inside a factory but spend most of their time exposed to the elements
of open-air production yards. Total stations that are transported while
still attached to their tripods to keep up with the hectic pace of daily
production. Reliability and performance is not to be compromised
even under such working conditions and although fine manufacturing
quality is to be recognised for this, the Leica Geosystems technical
service team provide the long term after market care.
Inspect, evaluate, adjust then certify equals accuracy and reliability
Daniel Parnham is one of the specialists committed to the care of TPS
5000 products from Leica Geosystems in the Czech metropolis on
the banks of the Vltava. He works closely with the Leica Geosystems
headquarters in Switzerland and has been responsible for leading
and developing the Prague servicing facilities from scratch. “This
room was completely empty and open to design when our plans were
constructed. We started with the basics such as chairs, desks, or
cupboards followed by antistatic ESD workbenches and purpose-made
optical and electronic diagnosis equipment. All this, and more, needed
to be tailor-made to meet the strict factory TPS Service requirements.”
explains Daniel.
His pioneering efforts soon bore fruit. The service processes, products
and efficient turn-around times are proving popular for customers.
Instruments arriving for servicing frequently leave this facility within
1 or 2 days. Daniel describes a sequence of events for a typical main-
tenance and recertification. “The first and most important step is the
incoming inspection. Our customers put their faith and trust that we
handle their goods with care; it is therefore our duty to control receipt
of all their items right down to the last detail. We look for transit
damage too and report anything untoward, no less than you would
expect.” Daniel mentions that this can often be a moment of reunion.
“Reliable instruments such as these usually mean we in service very
often see them every year for recertification; it’s like a long lasting re-
lationship!” Daniel continues: “Next is the status testing. This is where
we record all of our customer’s personal settings that are reinstated
prior to leaving service during our pre-exit testing procedure. As part
of the same process, the operational performance of all functionalities
are evaluated and recorded in a check list fashion. This describes the
current condition and enables decisions to be taken regarding what
attention the instrument requires from service. Leica Geosystems
Service Software manages this process for all mechanics, electronics,
optical components, laser groups and electrical drive systems.” No
fault goes undetected by the trained eye of the engineer. The online
diagnosis of many checklist points and the service specialists‘ ability
to interpret the test measurements correctly, are the perfect comple-
ment. Daniel explains: “If the process finds values that are clearly
outside the specified tolerances, then the repair process starts. The
necessary repairs are discussed and agreed with the instrument
owner and carried out as soon as the action tasks are approved.”

The final stage re-inspects the full functionality before conducting a
process used to identify measurement accuracy. This forms the bases
for traceable certification. Final exit inspection precedes cleaning and
preparation before packing and shipping. Daniel knows the precise
needs of his customers. Many industries that use Leica Geosystems
metrology equipment have concerns for their own stringent quality
assurance requirements to be met. To meet these standards, these
companies have their equipment regularly certified.
At the end of the tests, the Service Centre issues a full report showing
that the measurements produced by the instrument lie within the per-
mitted manufacturer’s tolerances. With total stations, the engineers
determine an offset coefficient for the distance meter derived from a
standard baseline. They also make spatial measurements over various
distances to traceable scale bars to investigate, evaluate and report
angle and distance component performance.
After all the test measurements, the engineer creates a Leica Geosys-
tems Producer Certificate which confirms the instrument meets the
measurement criteria. Daniel concludes: “The range of services we
offer is designed to satisfy the needs of our customers that use these
high accuracy industrial instruments daily. We take pleasure caring for
what are extremely reliable products. However, a service organisation
that is dedicated to after sales care not only enhances this reliability
but adds value through recording service history and extending the
product operating life too. We see this today with the many systems
that are still in use within Leica Geosystems’ very large install base!”

A laser tracker is a large volume inspec-
tion system that provides 3D coordinates
to a movable handheld target. A laser
beam is projected from the sensor, and
is then reflected back by the handheld
target allowing the horizontal and verti-
cal angles to be determined. The only
thing missing to be able to calculate the
handheld targets position in space is an
accurate distance.
Traditionally laser trackers have used laser
interferometers as the source for determin-
ing this distance between the handheld
target and the tracker. They have an almost
instantaneous update rate that is given
only by the speed at which the target can
be moved. This makes them perfect for
dynamic measurements, because no matter
how quickly the target accelerates the exact
change in location is immediately known
to the sub-micron level. This technology
makes laser trackers perfectly suited for
high speed dynamic measurements like
robot guidance and machine control, but at
the same time presents a strict limitation
on their usage. If at any time during the
measurements the beam is interrupted the
operator needs to go back to a known posi-
tion before anything else can be measured.
»
Leica Absolute InterferometerTechnology
01/09 measureup
18 Technology
In 1995 Leica Geosystems introduced the ADM or Absolute
Distance Meter to solve this limitation. An ADM can measure
absolute distances (i.e. distances to a point in a 3D coordinate
system) with extreme precision, but even the fastest ADM
will never be able to achieve the speed of an IFM for dynamic
measurements. All absolute distance meters must deal with
integration times, the time required to perform the operations
that determine the target’s position. This is similar to the shut-
ter speed on a camera, the longer the exposure time, the harder
it is to take a clear picture of a fast moving object. The same
is true with integration time, the longer the integration time,
the more likely you are to introduce an error in the measure-
ment of a moving object. An IFM doesn’t have this problem.
The change in distance is always immediately known. This is
what makes the AIFM or Absolute Interferometer in the Leica
Absolute Tracker revolutionary. Whether the beam is locked on
to a stable target, or to a moving target, the result is always the
same, and is typically within 5 microns. No other long range
distancing technology has ever been able to measure so ac-
curately, and at the same time provide such amazing dynamic
capabilities.
The AIFM provides a leading edge solution to an age old
problem, but does so using mature technology. The IFM and
ADM core technologies have been used for more than a decade
in our laser trackers around the world. These core technologies
have been improved and combined to create what Leica Geo-
systems have dubbed the “Absolute Interferometer”, or AIFM,
and represent the most accurate and stable dynamic distanc-
ing unit that we have ever created, making the Leica Absolute
Tracker Leica Geosystems‘ most functional laser tracker to date.
