Process Defaults and Thresholds
The table below lists some important plant variables. You can view all plant variables for a given process group within a specific VPE by using the following steps:
1 Select Tools > VPE Toolset, and then click the VPE Manager button in the VPE Toolset window.
2 Double click the desired VPE in the Select VPE window.
3 In the VPE Manager, click + to expand the Sheet Metal process group.
4 Under Sheet Metal, click Variables.
 
Variable Name
Description
defaultRectangularPartSpacing
Minimum space between parts when using rectangular nesting.
defaultUtilizationMethod
Eligible values: "COMPUTED" (rectangular), "TRUE_PART" & "MACHINE_DEFAULT"
enableScrapMaterialCredit
enableScrapPartCredit
minBendRadiusRatio
Factor to determine whether the bend radius is less than the recommended bend radius.
minStraightRadius
Minimum radius for a curve to be considered straight for the purpose of calculating laser cut feed rate. Feed rate is decreased for smaller radius curves; the maximum feed rate is used for straight sections.
waterjetAbrasiveCost
Cost of garnet abrasives for use in Waterjet Cutting. Used to calculate expendable tooling cost.
waterjetCornerAjustmentFactor
Additional cycle time applied to account for the extra time required to stop the feed rate at each corner during Waterjet Cutting.
waterjetCutTimeAdjustmentFactor
Adjustment applied to Waterjet cut time to account for the extra time required for acceleration or deceleration to the required feed rate.
waterjetInsertCost
Cost of inserts for use in Waterjet Cutting. Used to calculate expendable tooling cost.
waterjetInsertLife
Life in hours of inserts for use in Waterjet Cutting. Used to calculate expendable tooling cost.
waterjetKerf
Kerf width for a Waterjet Cut part.
waterjetMaxMixingTubeDiameter
Maximum possible diameter of the waterjet mixing tube.
waterjetMaxOrificeDiameter
Maximum possible diameter of the waterjet jeweled orifice.
waterjetMaxPartThickness
Maximum part thickness for Waterjet Cutting. Waterjets can actually cut thicker parts but the cutting model breaks down above this threshold.
waterjetMinPartThickness
Minimum part thickness for Waterjet Cutting.
waterjetSmallEdgeThreshold
Ratio of individual edge segment length to total perimeter length below which an edge is considered small and must be cut using a slower feed rate.
waterjetWallThicknessToDepthRatio
Minimum allowable ratio of wall thickness to part thickness for a Waterjet Cut part.
waterjetAbrasiveCost
Cost of garnet abrasives for use in Waterjet Cutting. Used to calculate expendable tooling cost.
