Fundamentals of GD&T ASME Y14.5 2018 - Advanced Level ET2151

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

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

Students should have basic knowledge and command of the GD&T ASME Y14.5 standard which provides guidelines for engineering drawing sheet layout.

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