Geometric computation and optimization on tolerance dimensioning

CAD Computer Aided Design, 2014
This paper presents an efficient geometric method of tolerance analysis for optimizing dimensioning and providing an optimal processing plan for a discrete part. Geometric primitives are used to represent part features, and dependencies in the dimensions between parts are represented by a topological graph. The ordering of these dependencies can have a

Geometric formulation of orientation tolerances

Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002
The rapid proliferation of coordinate measuring machines (CMM) triggered the need for precise and rigorous formulations of each tolerance concept. In this paper, we employ the concept of configuration space of symmetric features to define each type of datum features and orientation tolerances.

Geometric Tolerance Specification

2011
In conventional tolerancing, the efforts of designers are mainly directed at selecting suitable values for linear tolerances on part dimensions. These are either determined by trial and error through analysis calculations or optimized according to cost functions.
