Figure 2: Threaded bolt and nut. Project 3: You have asked to do analysis to a drawing operation which is used to form a cylindrical cup with inside diameter = 80 mm and Punch height = 60 mm. The starting blank size = 140 mm and the stock Blank Dp Rp thickness = 2.0 mm, determine a) Drawing force. b) Holding force. Die c) Drawing ratio. -Dp d) Reduction. e) Thiskness to diameter ratio, given that the tensile strength (a) of the sheet metal (low-carbon steel) = 300 MPa and yield Do strength = 175 MPa. The die corner radius = 8 mm. f) Does the operation seems feasible? discuss your results? How to make it feasibe in case it was not? g) Suggest at least 3 different products available in the market that could be produced by the deep drawing operation.
