CAD/CAPP Integration using Feature Ontology



C Dartigues, P Ghodous, Michael Gruninger, D Pallez, Ram D. Sriram


In a collaborative computer-supported engineering environment, the interoperation of various applications will need a representation that goes beyond the current geometry-based representation, which is inadequate for capturing semantic information. The primary purpose of this paper is to discuss a semantically-based information exchange protocol that will facilitate seamless interoperability among current and next generation computer-aided design systems (CAD) and between CAD and other systems that use product data. We describe an ontological approach to integrating computer-aided design (CAD) and computer-aided process planning (CAPP). Two commercial software applications are used to demonstrate our approach. The approach involves the development of a shared ontology and domain specific ontologies in the KIF (Knowledge Interchange Format) language. Domain specific ontologies--which are feature-based?are developed after a detailed analysis of the CAD and the CAPP software. Mapping between the domain ontologies and the shared ontology is achieved by several mapping rules. The approach is validated by using a variety of parts.
