Two Task Types Related To Setup
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 Two setup-related task types: Setup time is the sum-total of all on-line tasks!
Two setup-related task types: Tasks commonly done while the machine is down • Tear down old setup & put everything away • Clean machine • Make new setup • Cutting tool tasks • Assemble, measure, and enter offsets for • Assign program zero • Measure position and enter fixture offsets • Load program • Verify program • Optimize program The fewer the people in the CNC environment, the more tasks tend to be done on line
