Our Capabilities
Hommel-Etamic is a leading manufacturer and system provider of industrial metrology products throughout the global manufac-turing
industry. Consisting of high-precision, contact and non-contact production metrology, our range of products and services
cover total solutions for a wide range of measurement tasks such as testing roughness, contour and form plus determining dimen-sional
and geometric measurements – in-process, post-process or in the metrology lab. Our customer base consists primarily of
leading automobile manufacturers and suppliers, with a significant presence in medical, aerospace, construction, defense, and many
more.
With the recent downturn in the automotive market, Hommel-Etamic is in a key position to capture additional market share in
other areas of manufacturing excellence. Two main areas of expansion are the aerospace and medical manufacturing fields, both of
which require high precision measurement systems to maintain critical part quality. Hommel-Etamic has the edge on our competi-tion
due to our expert capabilities in three key fields of metrology: pneumatic, optical, and tactile. Optical systems consist of high
precision, flexible equipment for fast, precise, length measurements, geometric, form and positional tolerances, as well as optical
surface inspection. Our pneumatic systems consist of high precision, non-contact technology employing high pressure air for both
static and dynamic dimensional and geometric measurements. Last is tactile which covers form, contour, and in-process systems
offering the end user unparalleled control over part quality.
In addition to the above technological advantages, Hommel-Etamic also offers a wide range of services, available from almost any-where
on the globe, including: world-class design and development centers in Germany, France and Switzerland; (6) Major manu-facturing
centers in the U.S.A., France, Germany, Korea, and China; world-wide sales and service networks spanning 6 continents
in over 50 countries; and over 200 years of combined measurement experience.

Tactile measurement.
Highly accurate metrology with robust
scanning systems
The tactile method enables accurate measurements,
both for intermediate inspection and 100% inspection in
the production process.
The complex scanning systems of these measure-ment
instruments and machines measure surface
characteristics, contour, form, position and dimen-sional
tolerances of each work piece. Different
scanning systems can be used depending on the
measuring task, work pice geometry, and access
to the measurement location. For example, probes
with perfectly machined diamond styluses for
roughness measurements, ruby balls for form mea-surements,
or wear-resistant, dirt-repellant carbide
measuring probes for dimensional measurements.

How to measure precision shafts
to sub-micron accuracies in sec-onds?
High-precision non-contact optical shaft metrology is an invest-ment
which can pay off both in the SPC measuring stations oper-ated
by the workers and in the fully automatic systems for 100%
inspection.
The hardware and software for these systems are optimized for
use in a production environment and provide gauging component
capability with maximum reliability over long periods of time. The
non-tactile, optical sensor system operates totally without wear and
without the danger of collision. Ideal for worker self-inspection,
the systems are supported by intelligent and user-friendly man-machine
interfaces.
The characteristic high reliability and precision of these measuring
systems is particularly beneficial to the aerospace industry. Examples of existing applications are carrier shafts for aircraft engines and
drive parts in helicopters, including a measuring system for rotary parts with diameters up to 30mm and lengths up to 200mm. In
other applications, these shaft measuring systems have a measuring capacity for diameters up to 480mm and lengths up to 2500mm.
The nearly universal application for shaft-type work-pieces, offers maximum flexibility, and the potential to replace a number of con-ventional
gauging components. Dimensions such as lengths/distances can be measured as can geometry elements (angles, radii,, etc.)
and form and position tolerances (roundness, run-out) in a single pass.
Combining these evaluations into a single measuring program, the operator can generate relevant information for quality assurance
during the production process with one measurement from one measuring system. This is a big advantage, for example, compared to
a situation where conventional measuring machines would have to be reset and where large numbers of measurements exist. Flexible
work-holding devices with Morse tapers enable quick loading of new work pieces with negligible set-up times.
Offering long term gauging capability with accuracies in the um-range in very short cycle times, measurement results are available
within a few seconds. With conventional measuring systems, complete measurement of work pieces often last several minutes.
Measuring Principle
The workpiece is automatically scanned opto-electronically using the silhouette principle. The complete workpiece contour can be
evaluated quickly and precisely by the high measuring resolution per single measured value. The outside contour data of each work-piece
is recorded during the rotational movement. Any standard measurement functions can be combined depending on the measur-ing
program which then follow an optimized, automatic measuring run.
Simple to use
User control of the measuring systems is simple. Measuring programs can be created within minutes. The creation of part measur-ing
programs, display of, and further processing of the measurement results takes place simply and intuitively by means of a graphi-cal
user interface (GUY) in Windows XP. Depending on the measurement task, the worker can very quickly combine any standard
measuring functions in one automatically optimized measuring run.
To create a new test program, the measuring system is loaded with a work piece, which is then scanned completely and saved in the
program memory. This only lasts a few seconds. New added test characteristics can be selected by clicking with the cursor. This capa-bility
also guarantees future value for a wide range of applications, and the high measuring speed ensures very high productivity.
The calibration states of these measuring systems are monitored automatically by integrated, high-precision step discs and tempera-ture
sensors, which also form the basis for intelligent temperature compensation. Integrated step replace an additional setting master
for daily use. The active temperature compensation takes play automatically with every measuring run. The measuring system moni-tors
itself for negative ambient influences. This offers high safety and optimum comfort in production applications.
These systems offer a wide variety of flexibility for automatic or manual self inspection, and are proving their reliability at various
manufacturing sites around the world.
