02(20%) A 20 mm diameter and 30 mm height metal cup will be drawn from 3 mm thick blank. If the shear strength of the steel sheet is 35 kg/mm², calculate: a) Initial blank diameter b) Blanking load c) Deep drawing steps. (Assume redrawing ratios are: 1.43, 1.33, 1.25, 1.19, 1.14 and 1.11)

Step 1

We are given the final diameter ($D_f = 20$ mm), height ($H = 30$ mm), and thickness ($t = 3$ mm) of the cup. The shear strength of the steel sheet is given as $\tau = 35$ kg/mm². We need to find the initial blank diameter, blanking load, and the number of deep Show more…
