Event details:

Geometric dimensioning and tolerancing (GD&T) is a symbolic language that is used on engineering drawings to specify features of a part, including the size, shape, form, and orientation. GD&T was created to improve quality, reduce cost, and ensure that mating parts are assembled properly.

This course continues to build upon the topics and concepts from the Day 1 course, which include the history of GD&T, tolerances, datums, position and feature callouts, and basic GD&T symbols.

Specifically, participants will learn the 13 additional symbols, learn about acceptable methods for validating symbols, and perform hands-on exercises to practice what they have learned. 

Appropriate for:

  • Quality control/assurance technicians and inspectors; other manufacturing personnel whose jobs require the reading of engineering drawings and are new to manufacturing.
  • Individuals who have completed Purdue MEP’s GD&T Day 1 training.

You will learn:

  • Identify the 14 geometric tolerance symbols and explain what they mean.
  • Explain how geometric tolerances are measured in practice.
  • Write and interpret GD&T symbols on drawings.
  • Design a simple gauge.
