Interpret the various types of geometric tolerances (flatness, circularity, cylindricity*, straightness, perpendicularity, parallelism, angularity*, position, runout, and profile).Describe the concepts of worst-case boundary, virtual condition, and bonus tolerance.Recognize the symbols and modifiers used in GD&T.Describe the general dimensioning symbols*.Describe the types of dimensions, tolerances, and notes.Explain the importance of standards on engineering drawings*.Learning ObjectivesĪfter completing this advanced-level course, you’ll be able to: 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. This course provides a complete look at GD&T Fundamentals. 2018 Ultimate GD&T Pocket Guide, 2nd Edition.
Fundamentals of Geometric Dimensioning and Tolerancing 2018 Using Critical Thinking Skills textbook by Alex Krulikowski.Newly acquired learning is reinforced throughout the class with 150 practice exercises, including more than 80 application problems. Additional application thinking skills problems (applying the knowledge to a drawing).Examples of inspection methods for each geometric tolerance.Related and unrelated actual mating envelope.Discussions of verifications principles for each geometric tolerance.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.Interpreting cylindricity and angularity.Additional terms, concepts, and symbols used in GD&T.This in-depth, advance-level course also covers: 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. The course can be conducted in three 8-hour sessions or with flexible scheduling including five mornings or five afternoons. 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.
