Recognize these issues?
Different employees read and understand GD&T differently. There is no standard approach.
How can I better and unambiguously safeguard the functionality of my workpiece?
How can we help
First, we estimate the level of each participant. From there we arrive at a standard approach using practical exercises.
Course objectives
The main goal of the course is to get everyone into alignment regarding the application and interpretation of GD&T. There is time and space for discussion during the course. This sharpens communication and ensures that everyone is on the same page.
At the end of the two-day course, participants will be able to:
- correctly interpret any given GD&T.
- functionally apply GD&T tolerances independently, when formulating product specifications and producing drawings.
Target group
This course is suitable for a wide range of team members, including CAD engineers, work planners, quality control engineers and anyone else whose work requires a familiarity and understanding of GD&T.
