Sheet-metal blanks are loaded into a stamping operation by an industrial robot. Loading time is 15 sec. Actuating the OBI press takes 6 sec, including part ejection. The completed parts are dropped by gravity into a container. The cost rate of the press is $54/hr, which includes the cost rate of the robot. The sampling die cost $36,000 and is expected to produce a total of 80,000 stampings during its life. Batch quantity is 1,500 parts. Time to set up the press before production is 15 min. Assume availability = 100%, scrap rate = 0%. Determine

(a) time to complete the batch,
(b) average production rate, and
(c) cost per piece of the unit operation.
