Two setup-related task types:

On-line tasks:Tasks done while the machine is down between production runs

Off-line tasks:Tasks done while the machine is in production for the next (or some future) setup

Setup time is the sum-total of all on-line tasks!

Tasks commonly done while the machine is down

The fewer the people in the CNC environment, the more tasks tend to be done on line
