The design of cold extrusion process is usually carried out by an experienced expert from his own expertise, existing designs and process rules. This paper introduces the current situation of cold extrusion process planning and presents its future development. Furthermore, an integrated CAD/CAPP/CAE and optimal technique prototype system of process planning for cold extrusion based on feature models is put forward. It also analyzes the key techniques,such as feature modeling, feasibility checking, process planning, process evaluation and optimization and system integration. The prototype provides the method and possibility to establish the last integrated CAD/CAPP/CAE system of cold extrusion.
