GD&T Fundamentals (3-day)

  • Delivery Option: Public & On-Site
  • Subject Category: Technical
  • Cost: $1300
  • Number of Days: 3

Course Summary

This course is an introduction to the Y14.5 standard, focusing on the what, when, why, and the how of GD&T.

Target Audience

This program is designed for anyone who designs, drafts, engineers, purchases, manufactures, estimates, or inspects parts and assemblies. Particular emphasis is placed on those who design and manufacture, and those responsible for quality.

Prerequisites

A working understanding of technical drawings (perspectives, sections, details, etc.).  Blueprint Reading for Industry is suggested.

Course Objectives

  • Introduce the concepts and the some of the language of the Y14.5 standard.
  • Enable participants to understand each of the Y14.5 standard’s symbols.
  • Bring participants to a fundamental understanding of Datum Reference Frames.
  • Understand the definitions and the effects of Material Condition Modifiers.
  • Begin to prepare the participants for the ASME GDTP certification exam.

Benefits

Your drawings have GD&T symbols on them (or they should)! If you have been attempting to work with GD&T, and you lack the confidence to specify, or are having trouble interpreting the specifications, this GD&T training is for you. Using GD&T improperly can be worse than not using it at all.

 

What is the difference between our 2-day class and our 3-day class?  In both offerings the student is trained in important dimensioning concepts.  However, the primary difference is the 3-day class affords the student opportunity to cover each topic in more depth.

Agenda

 NOTE: This course differs from GD&T Fundamentals 2-day only in that it provides an additional day of training for hands-on print reading and project exercises.  The theory and materials used in these two courses are the same.
