The Response Surface Method Applied to Deep Drawing with Combined Restraint

Abstract

The deep drawing with combined restraint assures a greater degree of deformation in comparison with the conventional method of deformation. An important thickness variation appears during the deformation process. In the paper the method of the response surfaces for minimizing this variation has been applied. The response surface method considers the relation between the parameters of a process, in the present case, the die radius and the blank diameter and its characteristic answers as surfaces in the dimensional space of the variables, in this case, the thickness variation. An optimum value of the deforming parameters, is finally obtained.
