Fundamentals of GD&T 2009 3-day

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.

• 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. 

• 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.
