GPS ISO Standards – Level 2

Geometric Dimensioning and Tolerancing (GD&T) is the common, powerful language of industrial manufacturing. GD&T is recognized around the world as the only way of defining engineering drawings and CAD models efficiently and unambiguously. But the unfortunate reality is that most of the workforce that engages with mechanical drawings has an adequate understanding of this language. Many individuals and organizations get by for some time before costly or otherwise painful experiences convince them they need to improve their skills in use of GD&T.
The truth is that properly applied at the earliest stages of a product development project, GD&T can establish robust product quality, save months of development time, tens even hundreds of thousands of euros, and potentially millions over the lifecycle of a product.
GD&T training has real benefits: lower costs, less non‐conforming parts, higher tolerances.
InQuality, authorized partner of HEXAGON MI, offers on‐site and on‐line GD&T training courses.
Based on the latest ISO & ASME standards, our courses are tailor‐made to fully cover your particular needs.

The course is delivered as an intensive, two‐day programme that covers some of the more advanced concepts of geometrical tolerancing to ISO standards and their application and interpretation. Participants will discover how the functional specifications can be captured with the syntax of the tolerancing standards and how to choose the most effective tolerancing scheme for their application and process, will be able to define more advanced datum structures and to understand how to use the Maximum Material Condition modifier with datum references (datum shift).
This highly‐interactive course includes extensive classroom discussions, team exercises and problem‐solving sessions. Examples of drawings or components from the client, where available, are used in order to illustrate the course material. Suggestions to customize the course to specific participant needs can be discussed.
To maximize the effectiveness of the training, an upper limit to the class size of 10 delegates is recommended.

Anyone who is responsible for specifying, and interpreting, technical documentation: mechanical engineers, designers, managers, production planners, inspectors, machinists etc. Since this is an advanced level course, students should have completed the Level‐1 GD&T course, or equivalent, in order to comprehend the advanced level concepts.
