An engineer has been given the assignment of finding how much money can be saved over a year’s time by redesigning the press plates from the pattern shown in Fig. 4.18a to the pattern shown in Fig. 4.18b for stamping out 2.400-in.-diameter disks. The stamping material is 14-gauge sheet metal and can be purchased in 100-ft rolls in varying widths in 0.5-in. increments. One square foot of metal weighs 3.20 lb. The metal is sold for $0.20/lb. Do not consider the ends of the rolls. The company expects to produce 38 000 parts this year. How much can be saved?
