Fundamentals of GD&T ASME Y14.5 2018 - Advanced Level
I.D. # ET2151 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- 2018 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 models
  • General dimensioning symbols, including radius, controlled radius, spherical radius, diameter, spherical diameter, square, counterbore, spotface, depth, countersink, nX, ¿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 application thinking skills problems (applying the knowledge to a drawing)

Newly acquired learning is reinforced throughout the class with 150 practice exercises, including more than 80 application problems.¿

Each attendee receives:
  • Fundamentals of Geometric Dimensioning and Tolerancing 2018¿Using Critical Thinking Skills¿textbook by Alex Krulikowski
  • 2018 Ultimate GD&T Pocket Guide, 2nd Edition

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*
  • Describe the types of dimensions, tolerances, and notes
  • Describe 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 geometric tolerances (flatness, circularity, cylindricity*, straightness, perpendicularity, parallelism, angularity*, position, runout, and profile)
  • Describe the datum system
  • Interpret applications of datum targets, size datum features at RMB, and size datum features at 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
