In a batch machining operation, setup time is 1.5 hr and batch size is 80 units. The cycle
time consists of part handling time of 30 sec and processing time of 1.37 min. One part
is produced each cycle. Tool changes must be performed every 10 parts and this takes
2.0 min. Determine (a) average cycle time, (b) time to complete the batch, and (c) average
production rate.
