Fundamentals of GD&T ASME Y14.5 - 2009 Advanced Level ET1151

Topics: Quality, Safety & Maintenance


This 3-day Fundamentals of GD&T course provides an in-depth study of the terms, rules, symbols, and concepts of geometric dimensioning and tolerancing, as prescribed in the ASME Y14.5-2009 Standard. The course can be conducted in three 8-hour sessions or with flexible scheduling including five mornings or five afternoons. 

This class includes all the topics from the Fundamentals of GD&T 2-day foundational-level class: an explanation of geometric tolerances, including their symbols, tolerance zones, applicable modifiers, common applications, and limitations; Rules #1 and #2; the datum system; form and orientation controls, tolerance of position (RFS and MMC); runout and profile controls.

This in-depth, advance-level course also covers
  • Additional terms, concepts, and symbols used in GD&T
  • Interpreting cylindricity and angularity
  • Using tolerances on CAD models
  • General dimensioning symbols, including radius, controlled radius, spherical radius, diameter, spherical diameter, square, counterbore, spotface, depth, countersink, 'by,' maximum dimension, minimum dimension, reference, dimension origin
  • Discussions of verifications principles for each geometric tolerance
  • Related and unrelated actual mating envelope
  • Examples of inspection methods for each geometric tolerance
  • Additional thinking skills of application (applying the knowledge to a drawing)

Newly acquired learning is reinforced throughout the class with more than 150 practice exercises, including more than 50 application problems. 

Each attendee receives:
  • The Fundamentals of GD&T Using Critical Thinking Skills (ASME Y14.5-2009) textbook by Alex Krulikowski
  • GD&T Ultimate Pocket Guide (2009)

This course provides a complete look at GD&T Fundamentals. For more complex GD&T topics, like the expanded use of composite position and profile tolerances, customized datum reference frames, the translation modifier, and applying GD&T to non-rigid parts, see our Advanced Concepts of GD&T course. 

Learning Objectives

After completing this advanced-level course, you’ll be able to:

  • Define the key terms used in GD&T
  • Recognize the symbols and modifiers used in GD&T
  • Explain the rules used in GD&T
  • Describe the concepts of worst-case boundary, virtual condition, and bonus tolerance
  • Interpret the various types of tolerance (flatness, straightness, circularity, cylindricity*, perpendicularity, parallelism, angularity*, position, runout, and profile)
  • Describe the datum system
  • Interpret applications of datum targets, size datum features (RMB), and size datum features (MMB)
  • Perform position tolerance (RFS and MMC) special application and calculations*
  • Describe profile tolerance basic concepts and applications*
*Not covered in 2-day foundational-level course

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.
