Fundamentals of GD&T ASME Y14.5 - 2009 Advanced Level
I.D. # ET1151 Duration 3 Days

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:


  • Explain the importance of standards on engineering drawings*

  • Interpret the general dimensioning symbols*

  • 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
