Geometric Dimensioning & Tolerancing
Recognize critical information on the basics of Geometric Dimensioning and Tolerancing (GD&T). From there, dive into the more difficult principles through lectures, realistic examples, discussions and application problems. Understand how to interpret and apply ASME Y14.5M-2018.
Recognize and apply these techniques in datum selection and tolerancing optimization. This approach preserves functional product requirements, while taking into consideration manufacturing difficulties, introducing more producible tolerances, practical datum structures and preplanning measurement methods.
Participants are expected to purchase the following two books for class:
“Geometric Dimensioning and Tolerancing-Applications, Analysis & Measurement” [per ASME Y14.5-2018] ISBN: 978-0-578-47048-1
“WORKBOOK and ANSWERBOOK for GEOMETRIC DIMENSIONING and TOLERANCING” ISBN: 978-0-9714401-7-3
This course can be applied to the following certificates:
Dimensioning and Tolerancing Certificate
Elastomer Technology Certificate
Plastics Technology Certificate

Course Outline/Topics
1. GD&T basic principles
2. Geometric characteristics and inspection
3. Datum selection, choosing the perfect geometric characteristic for parts and assemblies. Fixed fastener assembly, mating part tolerance formulas and the effects of modifiers (MMB after datum features) are also emphasized
4. Producibility and measurement considerations
5. Holding direct vs indirect functional relationships in an assembly
6. Application of common tolerancing methods and datum structures
7. Commonalities in tolerancing approaches on dissimilar part geometries profile of a surface
8. Design, dimensioning and tolerancing of functional gages and fixtures. Quality assurance strategies and measurement planning
9. Converting from plus and minus tolerancing to positional tolerance
10. Composite position vs two single-segment positional tolerancing
11. Composite profile vs two single-segment profile tolerancing
12. Applying position tolerances to a complex assembly with multiple datum structures for floating and fixed-fastener assembly conditions
13. New concepts in Y14.5-2018 are explained and discussed, such as: dynamic profile, vector symbols, the return of true geometric counterparts and much more
