Interpret the various types of tolerance (flatness, straightness, circularity, perpendicularity, parallelism, 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 types of dimensions, tolerances, and notes used on drawings.Learning ObjectivesĪfter completing this foundational-level course, you’ll be able to:
It includes 20 additional practice exercises and more than 50 application problems.
It also explains cylindricity and angularity tolerances, position tolerance special applications and calculations, related and unrelated actual mating envelope, and profile applications. The Fundamentals of GD&T Using Critical Thinking Skills (ASME Y14.5-2009) textbook by Alex Krulikowskiįor more in-depth GD&T coverage, see our 3-day Fundamentals of GD&T advanced-level course, which covers everything from this 2-day course, plus these additional topics: drawing standards, the general dimensioning symbols, and using tolerances on CAD models.Newly acquired learning is reinforced throughout the class with more than 80 practice exercises. The class offers an explanation of geometric tolerances, their symbols, tolerance zones, applicable modifiers, common applications, and limitations. It explains Rules #1 and #2, form and orientation controls, the datum system, tolerance of position (RFS and MMC), runout, and profile controls. The 2-day foundational-level Fundamentals of GD&T course teaches the terms, rules, symbols, and concepts of geometric dimensioning and tolerancing, as prescribed in the ASME Y14.5-2009 Standard.
