Abstract
The initial blank geometry plays an important role on the quality of deep drawn parts. The present paper develops a new approach for optimizing the blank shape. In this approach the three-dimensional model of the final part is used to design an initial blank geometry for the given part. The deep drawing process is simulated using the initial blank shape. The blank is optimized in an iterative process based on the shape error and the deformation path length of the boundary nodes of the blank in the previous iteration. Optimum blank shapes for four case studies are determined. The results of the presented method are compared with some other methods in the literature and the presented method is found to be more efficient.
