The effect of drawing ratio in deep drawing process on thickness distribution along the cup

AbstractIn the present study the effect of drawing ratio in deep drawing process on the thickness distribution along the cup (wall, base and nose) has been performed. Obviously, the drawing ratio is the one of the most important parameter has been adopted to design the drawing die. Both experimental and numerical models were carried out on various drawing ratios (1.484, 1.589, 1.739, 1.908, 2.12 and 2.332).Tthe simulation results showed that the best drawing ratio is 1.484, which gives small difference between maximum and minimum thickness distribution along the cup. To examine the simulation results, experimental tests were performed one of the drawing ratios which shows the same behavior and pattern approximately. Keywords:ANSYS9, Deep Drawing Drawing ratio.
