Development of the optimal blank calculation system in deep-drawing by the slip line field method and CAD

Abstract

The slip line field method is applied in CAD system. This system can estimate the optimal blank shapes for deep-drawn containers of arbitrary convex shapes by using some CAD functions. This system is the Windows application, and the operativity is improved by the GUI. In this system, the special knowledges for plasticity are not required to the operators. And the operators easily obtain the optical blank shapes for their deep-drawn problems. Some optimal blank shapes are measured by using this system.
