All but the last station of a 6-station rotary-indexing machine perform machining operations and the last station is used for unloading and loading parts. The ongest process time is 2.5min and the loading/unloading time is less than this. It takes 9.2sec. to index the machine between workstations. Stations break down with a frequency of 0.018 , which is considered equal for all stations. When breakdowns occur, it takes an average of 5.3 min to diagnose the problem and make repairs.
