A method and the components of an implemented system for integrating design and manufacturing processes are presented. AI techniques like cooperative reasoning and combining geometric evidences are used in a graph-based hypothesis. This generate-eliminate approach automatically extracted the shape primitives of a designed part and determined the relationships between these shape primitives from the boundary representation CAD data, thus producing the higher-level semantic information necessary to manufacture the part. TOLTEC, a case-based planner, uses the information produced by the shape description system to construct a conceptual plan for machining the part. The shape description system, the process planner, and the interfaces are developed in Lisp. Examples of how IDP finds the shape primitives, analyzes their descriptions, and generates a machining process plan for two parts which posed difficulties for previous systems using feature extraction methodology.
