Cycle Time for Offline Blanking

Cycle time for Offline Blanking is calculated as follows described below.

Cycle Time = Process Time * Cycle Time Adjustment Factor

Cycle time is the product of the following:

• Process time: unadjusted cycle time for the current process. See the formula below.

• Cycle Time Adjustment Factor: value of the cost model variable cycleTimeAdjustmentFactor. This is set to 1 in aPriori starting point VPEs. VPE administrators can change the cost model variable to globally adjust cycle times.

Process Time = max(Press Cycle Time, Material Advance Time) /

Number Concurrent Parts

Process time is the larger of material advance time and press cycle time (since the coil advances as the machine opens and then closes again. It depends on the following:

• Press cycle time: specified by the machine property Press Cycle Time.

• Material advance time: reciprocal of material advance rate, which is interpolated from values looked up by part length in the lookup table pressMaterialAdvanceRate. aPriori converts the advance rate from strokes per minute to strokes per second.

• Number of concurrent parts: see Material Utilization and Part Nesting for Hydroforming.
