Abstract
Thickness distribution of deep drawing products has been studied in recent decades since it has a significant influence on the product quality. In this paper a numerical simulation with experimental verification was conducted to examine the influence of die radius on the thickness distribution of cilindrical cup in deep drawing for SS304 stainless steel. Thickness distribution of the cup was analyzed through the stress-strain state during deep drawing by Deform 3D software. The obtained results allow choosing a reasonable die radius to achieve more uniform wall thickness of the cup, that optimizes tool design and reduces manufacturing costs.
