following data resulted from a study taken on a horizontal milling machine: Pieces produced per cycle: 8. Average measured cycle time: 8.36 minutes. Average measured effort time per cycle: 4.62 minutes . Average rapid traverse time: 0.08 minutes. Average cutting time power feed: 3.66 minutes. Performance rating: 115 percent. Allowance (machine time): 10 percent . Allowance (manual time): 15 percent. The operator works on the job a full eight-hour day and produces 380 pieces. How many standard hours does the operator work? What is her efficiency for the eight-hour day?
