AUKOM Training explained

AUKOM Training explain

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. Today we look at exactly what the various stages of AUKOM training consist of. AUKOM is more than a common metrology language that will ensure effective communication across departments. It is a global training standard for production coordinate measurement practices which is vendor neutral. This means that the skills gained, and procedures learned during this certified training can be applied using any brand of measuring equipment and software. Here are the various stages of training in an easy-to-read menu form.

The various stages of AUKOM training in a menu form:

WENZEL is a member of ‚Ausbildung Koordinatenmesstechnik e. V. (AUKOM) and one of the leading providers of AUKOM training in North America. 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. By teaching a consistent methodology, AUKOM sets you and your team up to be on the same page which assist in execution between the engineering department to the metrology lab. The program consists of three levels and a certificate is provided for each upon passing the course exam.
