Shot Blast Cycle Time Calculation

Cycle Time = Process Time * Adjustment Factor

Cycle time includes setup time per part. It is the product of the following:

• Process time (see formula below)

• 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 times across processes within the current VPE.

Process Time = (Surface Area * Area Allowance) + (Contour Perimeter * Perimeter Allowance)

Process time depends on the following:

• Surface area (obtained from geometry extraction)

• Area Allowance (specified by the machine property Surface Area Allowance)

• Contour Perimeter (flattened part perimeter, for sheet metal parts; twice the sum of part length and part width, otherwise)

• Perimeter allowance (specified by the machine property Perimeter Allowance)
