Datum Schemes for GD&T


Many problems we face in industry, especially dimensional concerns, have faulty datum schemes as their root cause. Datum schemes must be explicit, functional, and repeatable. If any of these requirements are not met, financial loss occurs.

This mid-level two-day course begins with a fast-paced review of the basics, so you can bring your GD&T skills in line with the 2009 standard. Our primary focus is on datum strategies for assemblies and the detail components that comprise them. We teach you to spot datum problems so you can resolve these issues during product development.
