Abstract

Due to the incomplete representation schemes and the lack of high-level reasoning capability of current CAD/CAM systems, manufacturability assessment is performed by experienced designers and manufacturing engineers. The problems associated with automating manufacturing assessment include (1) the integration of a knowledge based environment within a design environment to provide reasoning capability, and (2) the development of flexible, modularized and responsive part models with levels of abstraction to support high-level reasoning which is required. Since modification of part geometries are frequently made during manufacturability assessment, the capability for part geometry modification is required at the level of interacting procedures. Consistency problems therefore occur between the geometric database in design environment and the part model in knowledge based environment. This paper presents a framework for an integrated design and manufacturability assessment environment which address these concerns.
