Bend Brake Cycle Time Calculation

Cycle Time = (Bending Cycle Time + (Load Time – Manipulation Time per Bend)) * Adjustment Factor

Cycle time is a function of the following:

• Bending cycle time (see formula below)

• Load time (looked up by part mass in the lookup table smBendBrakeHandling—where part mass is the product of material density and Part Volume)

• Manipulation time per bend (looked up by part mass in the lookup table smBendBrakeHandling). This value is subtracted to prevent the manipulation time for the first bend from being counted twice. This is necessary because bending cycle time includes manipulation time for every bend (see formula below), and load time includes manipulation time for the first bend.

• Adjustment factor (specified by the cost model variable cycleTimeAdjustmentFactor). This factor is 1 in aPriori starting point VPEs. VPE administrators can modify cycleTimeAdjustmentFactor in order to adjust cycle numBendOperations * (machine.bendCycleTime + manipulationTimePerBend)times across all processes within the current VPE.

Bending Cycle Time = Number of Bend Operations * (Bend Cycle Time + Manipulation Time Per Bend)

Bending cycle time depends on the following:

• Number of bend operations (sum of the PSOs Number of Bends and Number of Hemmed Bends)

• Bend cycle time for a single bend (specified by the machine property Bend Cycle Time)

• Manipulation time per bend (looked up by part mass in the lookup table smBendBrakeHandling)
