Abstract：

The choice of dies material in the classic process of die's design depends on experience of technicians, and it is blindfold. This is the disadvantage of computerizing the process of die's design. In this paper, the classical analysis method is used as theoretic basis of die's design. Each factor that affects the die's strengthen and diametric ratio is analyzed. Interrelations of each parameter are studied. The press ranges that are suitable for each design method are definition. All of these make the forecasting of the number of die's layers, the choice of die's material, the process of design more reasonable.
