Lu, Stephen C-Y Wilhelm, Robert G. 2011-05-07T13:11:09Z 2011-05-07T13:11:09Z 10000-01-01 1992 Computer methods for both analysis and synthesis of geometric tolerance specifications are developed to support the design of assemblies. Tolerance primitives, based on a sound theory of tolerancing, are used to represent tolerance relationships or links between geometric entities and functional requirements. Algorithms are developed for the determination of boundedness and the measurement of sufficiency. A detailed constraint network is used to represent tolerance relations for a part under design and provide for the composition of tolerance specifications. The constraint network is, in turn, associated with nominal solids describing the shape of the part under design. Query methods for the constraint network support the measurement of tolerance sufficiency and tolerance synthesis through optimization. The representation and computational methods are developed within a framework for tolerance synthesis which includes seven interconnected computing tasks. To demonstrate the improved facilities for tolerance specification which result from the integration and interaction within the framework, a prototype computing environment, CASCADE-T has been developed.
