PPT-Geometric Dimensioning and Tolerancing

Unit 2 Limits of Size Overview of Rules There are four general rules Taylors rule Limits of size Regardless of Feature Size RFS is the default Pitch cylinder axis is reference for thread and screws.

Describe the purpose of conventional tolerancing and its limitations. Use standard tables to specify an appropriate fit between two mating parts. Explain the advantages of using geometric dimensioning and tolerancing (GD&T) over conventional tolerancing. Unit 2 – Limits of Size. Overview of Rules. There are four general rules. Taylor’s rule.
