NDMC 0001 - Advanced Geometric Dimensioning & Tolerancing
Course Description
This Advanced Geometric Dimensioning and Tolerancing course is targeted at those who have already been trained in the basics of Geometric Dimensioning and Tolerancing. Even the most advanced practitioners will learn more than they ever thought possible in this two-and-a-half-day workshop.
Interpret and apply ASME Y14.5 Standard.
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
*Ordering note: please ensure your books arrive on time by ordering them over a week ahead of class.
Course Outline/Topics
1. Introductions/expectations
2. Refresher of GD&T principles from ASME Y14.5
3. Practical absolute gage tolerancing from ASME Y14.43
4. Methods of position tolerance verification (boundary method vs tolerance zone method)
5. Dimensioning and tolerancing rotating assemblies with hole patterns
6. Fixed fastener assembly tolerancing, threaded features, tolerance distribution and projected tolerance zones
7. Tolerancing mating parts using centerplane datum
8. Positional boundaries on elongated holes, pipes, hoses, tubes and D-shaped holes, all-around and all-over profile tolerancing
9. Profile, dynamic profile, compound datums, compound pattern datums, simultaneous and separate requirements
10. Flexible parts, sheet metal panels, elongated holes, positional boundaries and compound datum
11. Secondary and tertiary datum features of size, datum feature shift, displacement, angular orientation datums and simultaneous requirements
12. Oddly configured holes as datum features and the design, dimensioning and tolerancing of their gages and fixtures
13. Composite and two-single segment position and profile tolerancing
14. Converting from plus and minus tolerancing to composite positional tolerancing
15. Combining composite positional tolerancing with a simultaneous requirement
16. Using two single-segment position tolerancing on complex floating fastener assemblies with radial hole patterns
17. Weldments that use composite rolerancing inefficiently and datum selection poorly and how to connect them
18. Converting from plus and minus tolerancing to composite and two single- segment profile
19. PC board tolerancing and analysis
20. Analyzing collected variables data on oddly configured parts with profile tolerances
21. Tolerancing oddly configured mating parts
22. Tolerance stack-up analysis
23. Statistical tolerancing
24. New concepts in Y14.5-2018 are discussed (and compared to the 2009 and 1994 Standard)
Benefits and Learning Outcomes
- Identify step-by-step procedures for dimensioning and tolerancing parts and assemblies using rules found in ASME Y14.5 Standard
- Examine the connection found between the application of functional geometric tolerances and its effect on manufacturability and inspection
- Apply the ways to achieve a high-quality product at the lowest possible cost to the consumer
Notes
This program has a special two-and-a-half-day format, with adjournment on Day three at noon.
