AUKOM Training explained

Mariano-Cropped

It’s not obvious from the name what AUKOM training is so this blog is meant to explain.

In addition to offering training on the use of our measuring machines and specifically  in the use of OpenDMIS and WM Quartis software, WENZEL America offers training in Metrology in a generic sense, not specific to any software but applicable to all software or ensuring methods. Last year Mariano Marks, at the time our AUKOM trainer published a blog that laid out in detail the contents of the various stages of AUKOM training and it was very well received by customers eager to see what the opportunity was for them to up-skill in metrology. Here are the various stages of training in an easy to read menu form largely based on what Mariano described:

The various stages of AUKOM training in a menu form based on Mariano’s description:

WENZEL is a member of ‚Ausbildung Koordinatenmesstechnik e. V. ( (AUKOM)‘. The association promotes basic training in the field of industrial production metrology, in particular coordinate measuring. AUKOM ensures the standards and comparability of the courses offered by the members in the context of coordinate metrology training.
