The plastic forming is most important process in industrial production. The deep drawing, in particular, is indispendable for forming of various products. The forming efficiency of deep drawing is depend how various factors are controlled so that the decision of forming conditions becomes complicated. Therefore, numerical analysis is effective to estimate the optimum conditions of processing in deep drawing. In the present paper, the process of rectangular cup deep drawing has been treated. The relation between the punch shape and the plastic defomation of an alminum alloy sheet in the deep drawing was evaluated by the numerical analysis. As the result of this work, it is shown that a mutual relationship between blank size and punch shape decides the plastic flow of a sheet and has an infuluence on the processability of the deep drawing.
