Acompound die is used to blank and punch a large washer out of 6061st aluminum alloy sheet stock 3.2 mm thick. a compound die performs both the punching and blanking during the same operation. the outside diameter of the washer is 25.0 mm, and the inside diameter is 12.0 mm. determine the punch and die sizes for the
(a) blanking operation and
(b) punching operation. determine the force required to perform the blanking and punching operation under the following conditions:
(c) blanking and punching occur simultaneously and
(d) the punches are staggered so that punching occurs first, then blanking. the aluminum has a tensile strength
