Cycle Time Calculation

Cycle Time = (Press Cycle Time + Deep Draw Time + Material Advance Time) /

Number of Concurrent Parts

Cycle time is a function of the following:

• Press cycle time (specified as a machine property)

• Deep draw time (based on depth of deepest drawn feature, and cost model variable drawRate)

• Material advance time (increases with coil pitch—see the formula above; interpolated from values looked up by coil pitch in the lookup table pressMaterialAdvanceRate)

• Number of concurrent parts (1 by default, or specified by the process setup option Number of Parts Stamped Concurrently)

The lookup table pressMaterialAdvanceRate lists advance rates (in strokes per minute) by part length.
