Part Nesting Options
Note: these options are
ignored if Hydroforming is the primary process group; use
Sheet Material Stock Options in the Hydroforming process group, instead.
For Laser Cut, Fiber Laser Cut, Laser Punch, OxyFuel Cut, Plasma Cut, Plasma Punch, Waterjet Cut, and Turret Press, you can define the following setup options related to part nesting:
• Part Orientation: specifies whether the part’s tightest bend (that is, the bend with the smallest radius) is parallel to or perpendicular with the sheet grain.
o Not Specified. This is the default. aPriori selects the Digital Factory’s default orientation.
o Position Bend with Smallest Radius Parallel to Grain. Bends are sometimes oriented parallel with the grain, for example, in order to minimize cracking.
o Position Bend with Smallest Radius Perpendicular to Grain. Bends are sometimes oriented perpendicular to the grain, for example, to maximize strength.
• Part Spacing (trim around the part) for True-Part Shape Nesting: specifies the size of the margin around each part for true-part shape nesting.
o User override: user-specified margin in millimeters.
• Part Spacing (trim around the part) for Rectangular Nesting: specifies the size of the margin around each part for rectangular nesting.
o User override: user-specified margin in millimeters.
• Grain Direction: specifies how the grain is oriented on the sheet. Grain can run parallel to the sheet’s width or length. By default, grain direction is parallel to sheet length. These options are provided:
o Parallel to Sheet Length
o Parallel to Sheet Width
• Step Angle for True-Part Shape Nesting: specifies the part rotations aPriori considers in order to optimize nesting. aPriori considers non-negative, whole number multiples of this value that are less than 360 degrees.
o Default value: 90 degrees in starting point Digital Factories. Administrators can customize the default with the cost model variable defaultUtilizationStepAngle.
o User override: user-specified value between 1 and 360 degrees.
• Sheet Length Trim Strip: non-nestable margin on either end of the sheet's length: specifies the size of the margin that runs along the width of the sheet on both sides. The margin is required to feed the sheet through the machine.
o Default value: specified by the machine property sheetLengthTrimStrip, if there is one. Otherwise specified by the cost model variable standardLaserCutLeadInAmount (10mm in starting point Digital Factories).
o User override: user-specified margin in millimeters.
• Sheet Width Trim Strip: non-nestable margin on either end of the sheet's width: specifies the size of the margin that runs along the length of the sheet on both sides. The margin is required to feed the sheet through the machine.
o Default value: specified by the machine property sheetWidthTrimStrip, if there is one. Otherwise specified by the cost model variable standardLaserCutLeadInAmount (10mm in starting point Digital Factories).
o User override: user-specified margin in millimeters.
