| Abstract: | By using the technique of NURBS, the surface generation based on complex curve was discussed, and an algorithm of surface generation applied to die face design was presented. The algorithm is suitable to generate additional surface such as the fill-hole surface, the smooth surface of the automotive panel contour, the addendum surface and so on. The relevant function modules for parametric design were developed. The feasibility of the technique was proved by the simulation result which creates the additional surface of the front fender and the doorframe successfully. |
