CAD feature development and abstraction for process planning
Development and automatic abstraction of features directly from CAD (Computer Aided Design) database can form a vital link between CAD and CAPP (Computer Aided Process Planning). This thesis is an effort of developing a system for the integration of CAD and CAPP using the feature-based design approach. Parts are represented as collections of manufacturable features in the CAD database and an abstraction algorithm is used to retrieve the part definitions and their feature components from the CAD database. The abstracted data is then transformed into a neutral data representation called the Common Data Model (CDM) that is then reformatted to serve as the input for a process planner. The emphasis is on the support of multiple CAD and CAPP systems. The successful functioning of the approach is supported by a prototype system that uses commercially available CAD and CAPP software.
