摘要：
Asymmetrical cup drawing operations have been analysed employing the method of plane stress characteristics. Optimum blank shapes can be developed rapidly and accurately using a personal computer. In the present study the network of characteristics is continuously updated to account for the change in geometry of the outside edge of the blank, as the material is drawn into the die. It was found that the predicted blank shapes were in close agreement with those determined using a finite element analysis. In addition the predicted profiles correspond with experimentally determined optimum blank shapes when deep drawing square cups.
