Benefits and Learning Outcomes

• Learn step-by-step procedures for dimensioning and tolerancing parts and assemblies using rules found in ASME Y14.5 Standard
• Understand 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

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)
