Abstract：

Based on the characteristics of extrusion process, a new method of constructing surface for the streamlined extrusion die is proposed in this paper. The die surface is represented by the Ferguson surface with tension parameter through transverse sections of product and billet, so it is universal and flexible. A CAD / CAM system of the streamlined extrusion die is developed based on this die surface model.
