In this paper the deep drawing of sheet metal forming method, is very useful in industrial field because of its efficiency. In order to obtain the optimal products in deep drawing process, the deep drawing is affected by many process variables, such as blank shapes, profile radii of punch and die, formability of materials and so on. Especially, blank shape is very important formability factor. In this study, in order to investigate the effects of blank shape, we suggested three kinds of blank shapes and examined the friction test about three conditions. We measured the punch load distribution according to punch stroke under the conditions of profile radii of punch and die and observed the punch load of non-axisymmetric formability.
