Protomatic Offers Classes to Improve GD&T Accuracy

When GD&T (Geometric Dimensioning and Tolerancing) is poorly specified or incorrectly interpreted, many things can happen. All of them bad.

  • Datum schemes are incomplete, irrational or in conflict
  • Features related to these datums are ill defined, incomplete or open to interpretation
  • Up to 80% of drawings are estimated to be dimensionally deficient

There is no question that GD&T accuracy is a growing concern. It is very important that engineers refresh themselves on the subject; and that purchasing agents, managers and support personnel who work with GD&T understand the concepts.

Protomatic to offer GD&T classes

Protomatic, a precision CNC manufacturer, has teamed with M and M Consulting to provide expert GD&T training for individuals in manufacturing. A series of two-day, open enrollment courses will be held at the Protomatic training facility in Dexter, Michigan (just 10 miles from Ann Arbor). The sessions will be August 1 & 2 and August 28 & 29. Fee is $650 per person.

What is covered

In this two-day GD&T course, you’ll learn how to correctly apply and interpret its rules, definitions, principles and symbols per the American National Standard (ASME Y14.5 – 2009). The course provides a common language, so set-up requirements and tolerance zones are clearly understood. Topics to include:

  • Definitions and fundamental rules
  • Dimensions, tolerances and GD&T
  • Datum features and schemes
  • Form, orientation, location, profile, and runout tolerances
  • Related thoughts
  • A business case for GD&T
