A drawing operation is used to form a cylindrical cup with inside

A drawing operation is used to form a cylindrical cup with inside diameter = 80 mm and height = 60 mm. The starting blank size = 140 mm and the stock thickness = 2.0 mm, determine (a) drawing force, (b) holding force, (c) drawing ratio. (d) reduction, (e) thiskness to diameter ratio, given that the tensile strength of the sheet metal (low-carbon steel) = 300 MPa and yield strength = 175 MPa. The die corner radius = 8 mm, (f) Does the operation seem feasible? discuss your results? %3D - Punch Blank Do Rp -Die Do (a) Do
