AbstractThe aim of this study is to determine the optimal blank shape for a square cup drawing with uniform flange (square and circular flange).A new algorithm is proposed to control of flange shape based on shape error. To reduce earing defects on boundary of deformed flange, the initial blank shape was iteratively modified. This modification is repeated until an optimal blank shape for the part is achieved. To
apply this algorithm, 3D model of deep drawing was used and analyzed by Ansys 11.0 FEM code. Low carbon steel was chosen to carryout the simulation. The results show that the shape of optimum blank has significantly reduced the earing defects in few iterations
by using this algorithm.
