Question

8. In a deep drawing operation, a cup is drawn from a sheet metal with the inside diameter = 80 mm and the height = 50 mm. The stock thickness = 3.0 mm, and the starting blank diameter = 150 mm. Punch and die radii = 4 mm. Tensile strength and yield strengths of the sheet material is 400 MPa and 180 MPa, respectively. Determine (a) Feasibility of drawing (b) Reduction (c) Number of draws required (d) Die and punch sizes (e) Drawing force, and (f) Blank holder force. (10)
