Readers will learn:

1. How to convert from plus and minus tolerancing to geometric tolerancing.

2. When Position Tolerancing applies, its tolerance zones and the boundaries it creates.

3. How to select, define and tolerance datum features.

4. How size controls form.

5. How to measure MMC and LMC.

6. How to apply geometric tolerances of flatness, perpendicularity and position in sequence.

7. The tolerance zone configuration for flatness and varieties of perpendicularity.

8. How to calculate and distribute mating part tolerances.

9. Practical Absolute Functional Gage design, dimensioning and tolerancing.

10. How to calculate bonus tolerance for position, perpendicularity, angularity and parallelism when modified at MMC.

11. The difference between using MMC symbology after geometric tolerances (tolerance zone growth) and MMB symbology after datum features (datum feature shift).

12. How to calculate when a feature complies with its position tolerance and when it does not (variables data collection and analysis using CMM type data).

13. How to use charts for inches or millimeters to determine position tolerance compliance.

14. The meaning of Actual Mating Envelope and Actual Mating Size (both oriented and∕or located vs. unoriented, unlocated) for tolerance compliance.

15. How to use gages to help understand geometric controls and use of maximum material condition and maximum material boundary symbols.
