Advanced Concepts of GD&T ASME Y14.5M 1994 - Foundational Level ET2411

Topics: Quality, Safety & Maintenance


This 2-day foundational-level course teaches advanced geometric dimensioning and tolerancing topics as prescribed in the ASME Y14.5M-1994 Standard. 

The class offers an in-depth explanation of advanced GD&T topics including:
  • Product design and functional dimensioning
  • Feature and feature of size
  • Dimensioning standards on drawings
  • Rigid and flexible (non-rigid) parts
  • Requirements for parts measured in the restrained state
  • Datum usage on restrained (non-rigid) parts
  • Calculating advanced applications of form controls
  • Uses, advantages, misconceptions, and common errors of the datum system
  • Nine common datum feature types
  • Advanced datum target concepts
  • Modifier usage in tolerance of position applications
  • The effects of simultaneous and separate requirements with tolerance of position
  • Composite and multiple single-segment position and profile tolerancing
  • Profile applications

Each participant receives: An Advanced Concepts of GD&T (ASME Y14.5M-1994) textbook,  A GD&T Ultimate Pocket Guide (1994), and A Fundamentals of GD&T Exercise Workbook.

Newly acquired learning is reinforced throughout the class with approximately 200 practice problems. For additional advanced GD&T topics, including a discussion of the fundamentals of drawing interpretation, how to handle substandard drawings, how to specify/interpret specialized datum feature applications, interpreting tolerance of position applications with a conical tolerance zone, and 50 additional practice exercises, see our Advanced Concepts of GD&T 3-day advanced-level course.

Learning Objectives

After completing this course, you will be able to: 

  • Explain the importance of product design and functional dimensioning
  • Define the terms “feature” and “feature of size”
  • Recognize which dimensioning standards apply to an engineering drawing
  • Recognize the difference between a rigid and a flexible (non-rigid) part
  • State the requirements for tolerancing parts measured in the restrained state
  • Identify the two special considerations for datum usage on restrained (non-rigid parts
  • Calculate advanced applications of form controls
  • Describe advanced datum target concepts
  • Describe modifier usage in tolerance of position applications
  • Describe the effects of simultaneous and separate requirements with tolerance of position
  • Explain composite position tolerancing and multiple single-segment position tolerancing
  • Explain composite profile tolerancing and multiple single-segment profile tolerancing
  • Describe profile applications

Who Should Attend

This course is valuable for individuals who create or interpret engineering drawings: product and gage designers; process, product, and manufacturing engineers; supplier quality engineers/professionals; CMM operators; buyers/purchasers; checkers; inspectors; technicians; and sales engineers/professionals.

Prerequisites

Please be aware that this is not an introductory course. In order to understand the course content, participants should have completed the Fundamentals of GD&T course or equivalent.

You must complete all course contact hours and successfully pass the learning assessment to obtain CEUs.
