Abstract – In this paper, the friction aided deep drawing using tapered blank holder divided into four and eight segments is studied. Several parameters including effect of blank holder force, radial displacement of blank holder and punch force on cup height are investigated in the four segments tapered blank holder technique. The drawing mechanism and the effects of drawing conditions are also studied using ABAQUS/explicit software to show the merits of the process. Using the four segments type may cause a non-uniform flow of material in the flange portion; however, the eight segments type can overcome this deficiency. Therefore, the drawing mechanism of eight segments tapered blank holder technique and in-flow of material in the flange portion of blank are mainly investigated and compared with those from four segments tapered blank holder. A successful deep cup of drawing ratio 3.67 can be produced without any defect by using eight segments tapered blank holder technique. The cost and time of die fabrication in these techniques are less than the conventional deep drawing.
