About the course Geometrical dimensioning and tolerancing

Dimensioning, Surface Texture and Geometrical Dimensioning and Tolerancing make up the Geometric Product Specification (GPS).

In this training you will learn to now the most important principles and rules of the new ISO GDT standards for dimensional and geometric tolerancing and apply them functionally. Fully understand the logic of geometric tolerancing and safely avoid tolerance errors.

Knowledge is shared by on-line or in class training supported by video’s, examples and exercises.


Reduce costs and increase product quality by specifying according to current ISO-GPS standards

Module I

    • The GPS matrix model (ISO 14638)
    • Overview of the most common tolerance errors in construction drawings

It was extremely useful training to have since i use GD&T day to day basis.
Babu Shamanna, ASML
Very good training and worth while doing before we are all forced to shift to PMI its good to get our GDT knowledge up to scratch. Would recommend to others.
John Leo, ASML
I enjoyed the course, Hans is a good instructor, even though this was an online course he kept the our attention mostly. Sometimes it was hard to keep up with the topics but it was ok for me. Topics, extra materials were well organized and well defined.
Oyku Gungor, ASML
Well organized, well taught, good engagement
Joao Rodrigues, ASML
The course is very relevant and gives good insight on how to effectively convey design intent and set control parameters for designer to achieve desired outcome. Despite online presentation, the presenter showed a lot of insight and provided enough room for discussion Q and A.
Freddy Amisi, ASML

Discover the possibilities to organise this course in-company

If you want to train several employees in your company, it is more interesting and cheaper to organize a course at your location. Good coordination with your company-specific situation and the deployment of highly experienced lecturers who have earned their spurs in practice is essential here. Mikrocentrum is CEDEO-recognized and guarantees the best quality.
