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*
- Describe the types of dimensions, tolerances, and notes used on 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.
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.
