AUKOM TRAINING
Objective of the organisation
Manufacturer-neutral training in coordinate metrology
The objective of the “Ausbildung Koordinatenmesstechnik e. V. – AUKOM” is to ensure
an up-to-date, comparable, controllable and certifiable training in coordinate metrology
in accordance with its capabilities. The organisation promotes the basic, comprehensive
and solid training in the area of industrial production metrology, particularly in the area of
coordinate metrology. The organisation ensures the standard and comparability of the
courses offered by the members of the organisation within the coordinate metrology
training. It organizes events for promoting the exchange between manufacturers, users
and science in the area of coordinate metrology training and publishes new findings
and trends from this area. It develops, promotes and spreads the “good measurement
practice” and furthers the Europeanisation of cooperation in coordinate metrology
training.
Objective of AUKOM e.V.
Providing a machine-independent training concept, including established and practicetested procedures with interfaces for the manufacturer-specific machine training ending
with a final test and a generally accepted certificate.
History
During a three-year research project (1998–2001) of the Quality Research Association
(FQS), financed by the German Ministry of Labor and Economy, in cooperation with the
most important manufacturers and some of the heavy users of coordinate measuring
machines and with science at the QFM faculty of the University of Erlangen-Nürnberg,
a training concept for coordinate metrology was set up. The participants in the research
project and other interested parties formed an organisation named “Ausbildung
Koordinatenmesstechnik e.V.” at the end of the project in 2001.
