چکیده:

The optimum blank shape is the minimization of the difference between the target contour of the part and the outer contour of the deformed blank. The main objective of this paper is to introduce a new blank design method based on iterative finite element (FE) sheet metal forming simulations. The algorithm is based on the projection of the target contour on the deformed blank and accordingly modifying the original blank shape. The developed algorithm is applied to S rail channel part and a square cup drawing in order to confirm its validity
