Flexible multi-point die is more excellent than traditional method for skin stretch forming. The origin and current status of fl exible multi-point die are introduced, and the generation system is expounded with an emphasis. The system needs to generate the adjusted data for the multi-point die stretch, which is the important link between the preceding and the following. The realization of key algorithm, technology and function of profile generation system is discussed by using CATIA secondary development tool CAA.
