Bar stock of initial diameter = 90 mm is drawn with a draft = 15 mm. The draw die has an entrance angle 18, and the coefficient of friction at the work-die interface 0.08. The metal behaves as a perfectly plastic material with yield stress 105 MPa. Determine (a) area reduction, (b) draw stress, (c) draw force required for the operation, and (d) power to perform the operation if exit velocity-1.0 m/min Q7) Bar stock of initial diameter = 90 mm is drawn with a draft = 15 mm.
