Abstract

Design for assembly analysis procedures require certain geometric properties for each component part and sub-assembly. Algorithms have been developed for extracting this geometric information directly from a CAD system data base. This paper describes the implementation of these procedures and demonstrates their use by application to typical assembly. A wire frame geometric model of each component is developed and then graph theory used to determine automatically such features as part size and symmetry. © 1989 CIRP.
