Abstract

Deep drawing process, one of sheet metal formingmethods, is very useful in industrial field because of itsefficiency. The production of optimal products using thisprocess is dependent on the process variables such as blankshapes, profile radii of punch and die, and formability ofmaterials. Of the variables, the blank shape is very importantsince it controls the formability factor. This paper reports theinvestigations on three kinds of blank shapes and the scribedcircle test on three deformation modes. The punch loaddistribution for elliptical forming processes were measuredunder different conditions of profile radii of punch and dieand discussed here. These experiments clarified the influenceof the profile radii of the punch and die and the blank shapeon the punch-load distribution for the elliptical deep drawingproduct of automobile parts. The aim of this study is toinvestigate the effect that the process variables have ondrawability in a non-axisymmetric elliptical deep-drawingprocess and to obtain useful data from the industrial field.
