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.¿
