Geometric Dimensioning and Tolerancing (GD&T)

Course Description

GD&T is an information packed course presented through lecture, demonstration, discussion, and written exercises that will provide participants with the tolerancing tools and techniques to:

  • Ensure interchangeability of mating parts

  • Improve quality and productivity

  • Bid new contracts with confidence

  • Interpret and apply ASME Y14.5M-2009 & ASME Y14.5-2018 standards

Course Objectives

Upon completion of the course the participants will be able to:

  • Demonstrate the dramatic advantages of GD&T over traditional tolerancing schemes

  • Identify and properly use Symbols, Terms, and Rules

  • Apply and interpret datums properly

  • Apply and interpret Form, Orientation and Location controls

  • Specify and interpret typical applications of the Position control

Suggested Participants
Mechanical Engineers
Quality Engineers
Mechanical Inspectors
Design Engineers
Manufacturing Engineers
Machinists
Anyone who may be required to produce or interpret engineering drawings. Participants should have drawing background.
