Fundamentals of GD&T ASME Y14.5 2018 - 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 Y14.5-2018 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.

• 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.
