To better define a product, geometric dimensioning and tolerancing (GD&T) is often used as a symbolic way to show tolerances on mechanical drawings. This one-day course covers the GD&T system per ASME Y14.5-2009, including why it reduces costs, how to interpret the symbols, and how to apply these tolerances correctly. Participants will learn the basic definitions and rules, the importance of datums, the meaning of each tolerance, and the impact on manufacturing and gaging. The class is a lecture format, with ample opportunity for questions, and participants are welcome to bring sample prints (with or without GD&T already applied) to discuss with the instructor during breaks or after the class.            

 

A spiral binding book for GD&T will be provided.

Instructor

John-Paul Belanger is president of Geometric Learning Systems, based in Rochester Hills, Michigan. He is certified as a Senior-Level GD&T Professional by the American Society of Mechanical Engineers. Mr. Belanger has been a full-time GD&T instructor and consultant for 20 years, traveling throughout North America and Europe helping corporate groups implement GD&T properly in design, manufacturing, and inspection activities.  He holds a degree in aerospace engineering from the University of Michigan, specializing in aircraft design and safety.

  

Learning Objectives

By attending this seminar, you will be able to:

  • Explain the benefits of geometric tolerancing.
  • Identify datum features and determine their order of precedence.
  • Identify and interpret each of the characteristic symbols.
  • Describe the material condition modifers and how "bonus" tolerance occurs.
  • Correctly interpret GD&T feature control frames, and explain the impact on manufacturing and inspection.

  

Who Should Attend

This course is ideal for anyone who has a need to apply or interpret geometric tolerances on a product print. Product engineers, manufacturing engineers, CAD designers, quality inspectors, and other engineering and manufacturing personnel will all benefit from becoming fluent in GD&T.

 

Prerequisites

Participants should have knowledge of basic blueprint reading.
