Abstract
The design optimization of deep drawing process in manufacturing is proposed
to control the final shape of the work piece after elastic spring back. The manufacturing
process design problem is formulated to minimize the difference between the shape of the
desired work piece geometry and the final analysis. This paper aims to predict the
wrinkling and thinning (necking) failure and to study the effect of using draw bead on
the thickness distribution along the cup. In this paper to analysis the deep drawing
process with draw beads the FEM code (ANSYS) version 12.1 packages is used, which is
able to simulate various metal forming processes such as deep drawing. The best results
and the low variation between the maximum thickness and minimum thickness is found
at the half circle shapes of Draw Bead and itَ s about 10.4% thinning and 26.5%
thickening
