Abstract
The main focus of this research is to develop a mathematical model for GD&T (Geometric Dimensioning and Tolerancing) to support tolerance specification, validation and tolerance analysis. The model should be built on the clear definition of GD&T, both in terms of semantics and syntax. The current tolerance standards (Y14.5M-1994 and ISO 1101-1983) have many inconsistencies. We present a rational basis for GD&T by examining the basic elements involved in geometric variation and their interrelations. Tolerance classes are defined in terms of a target, a datum reference frame, and geometric relations. The GD&T global model developed is the basis for a set of computer tools for automatically generating and validating dimension and tolerance specifications based on the functionality of the part, checking dimensioning status and tolerancing status, and applying GD&T advisor.
