Geometrical dimensioning and tolerancing

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
