A feature-based process planning approach for fineblanking-forming-stamping parts

摘要

A feature-based process planning approach for fineblanking-forming-stamping parts is discussed in this paper. To reduce the dependence of experience designers and improve the design efficiency and quality, a prototype of feature-based process planning system has been established. The system consists of four major modules: forming process recognition, feature representation, operation sequence design and parametric feature modeling. The graph-based process recognition and feature representation methods are introduced. The knowledge-based methods are also used for process planning. An application example is illustrated.
