Punch Load of Non-Axisymmetric Deep Drawing Product According to Blank Shape

Deep drawing process, because of its efficiency is very much sought in sheet metal forming industries. The production of optimal products using this process is dependent on the process variables such as blank shapes, profile radii of punch and die and formability of the material. Out of these variables, blank shape is very important since it controls the formability factor. This paper reports the investigations on three kinds of blank shapes and the friction test on these three conditions. The punch load distributions for non-axisymmetric forming processes were measured under different conditions of profile radii of punch and die and discussed here.
