a. How do you classify the time for a drill press operator who is idle for a few minutes at the beginning of every job waiting for the setup person to complete the setup? Some of the setup time is used in going for stock, but the operator typically returns with stock before the setup person is finished with the setup.
b. 1. How do you classify the time for a machine operator who, between every job and sometimes in the middle of jobs, turns off the machine and goes for stock?
2. The operator drops a part, which you pick up and hand to him. Does this make any difference in a time study? If so, how?
