Abstract: Based on principle of probability and statistics, concerning the influence of material mechanical properties and random distributed thickness, the calculating model and the calculating formula of punch force is advanced. So how the material random behavior affect the punch force can be given quantitatively, and also probability design of the punch die can be made. The method given in this paper overcame the limitation of the classical theory. In addition, it is also given that classical theory is only a special example of the theory given.
