A compound die is used to blank and punch a large washer out of 6061ST aluminum alloy sheetstock 3.2 mm thick. The outside diameter of the washer is 25.0 mm, and the inside diameter is 12.0mm. Determine (a) the punch and die sizes for the blanking and punching operations, (b) the forcerequired to perform the blanking and punching operation under the following conditions: (a) blankingand punching occur simultaneously and (b) the punches are staggered so that punching occurs first,then blanking. The aluminum has a tensile strength = 350 MPa.
