Deep drawing is a sheet metal forming process that is commonly used in industry due to its efficiency. In deep drawing a sheet metal blank is drawn over a die cavity using a shaped punch. AS the blank is drawn radially inwards the flange undergoes radial tension and circumferential compression[1]. The latter may cause wrinkling of the flange if the draw ratio is large, or if the cup diameter-to-thickness ratio is high. A blank-holder usually applies sufficient pressure on the blank to prevent wrinkling[2]. The radial tensile stress of the flange is entirely governed by the punch. Hence, when drawing cups at larger draw ratios, increased radial tension requires higher tensile stress of the material. Bending and unbending over the die radius are also provided by this tensile stress on the cup wall. In addition, the tension on the cup wall has to help overcome frictional resistance at the die interfaces. Due to the allowable tensile stress of material, the maximum draw ratio is about 2.1 or 2.2. In order to draw deeper cups, altenative process must be used, e.g. o-forming[3], hydro-mechanical forming[4], counter-pressure deep drawing[5], hydraulic-pressure-augmented deep drawing[6], etc. These processes are relatively slow, and the maximum draw is limited to 3.5 or 4.0. However, in a conventional drawing process, the cup can be drawn in multiple steps to obtain draw ratios of 5 or higher
