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