In general, deep drawing products have various cross-section shapes such as cylindrical, rectangular and nonaxisymmetric shapes. The application of the surface area calculation to non-axisymmetric deep drawing process has not been published yet. In this research, a surface area calculation for non-axisymmetric deep drawing products with elliptical shape was constructed for a design of blank sha...

Abstract One of the commonly used metal forming processes is deep drawing, in which circular blanks are converted into a cup or shell with good surface finish. In this paper, the forming characteristics of Deep Draw Steel (DDS), a low-carbon steel with many engineering and automotive applications, is investigated by deep drawing. The forming limit diagram is a useful concept in favor of charact...

Primljeno (Received): 2011-10-10 Prihvaćeno (Accepted): 2012-02-09 Original scientific paper It is well-known from practice that only some cups whose height is smaller than diameter can be successfully drawn in one step. Many steps require more tools and larger total manufacturing costs. The main objective of this study was to minimize the number of deep-drawing steps. The paper presents the ap...
