Polygon Turning Options
Polygon Turning provides the following setup options:
• Number of Finishing Passes: By default, the number of finishing passes (the number of times the tool traverses the length of the feature) depends on the following:
o Value of the geometric property Max Enclosed Circle Diameter
o Value of the geometric property Min Enclosing Circle Diameter
o Tool cut depth (looked up in the lookup table tblPolygonTurning)
Default Number of Finihing Passes =
roundup((Max Enclosed Circle Diameter – Min Enclosing Circle Diameter) / 2) /
Tool Cut Depth
With this setup option, you can override the default on a per-GCD basis.
The number of finishing passes drives cycle time.
• Requested Cutter Diameter: By default, tool diameter is the product (snapped up to the nearest standard tool size) of the following:
o Value of the geometric property Max Enclosed Circle Diameter (approximate diameter of the workpiece at the point of cut)
o Value of the cost model variable PolygonTurningToolToWorkpieceRatio (3 in starting point Digital Factories)
With this setup option, you can override the default on a per-GCD basis.
Speed and feed are interpolated based on values looked up by tool diameter in the lookup table tblPolygonTurning. These values drive chipmaking time and cycle time.
• Requested Tool Cutting Speed: By default, tool speed is interpolated based on values looked up in the lookup table tblPolygonTurning. With this setup option, you can override the default on a per-GCD basis. Tool speed drives chipmaking time and cycle time.
• Requested Feed per Rev: By default, tool feed is interpolated based on valued looked up in the lookup table tblPolygonTurning. With this setup option, you can override the default on a per-GCD basis. Tool feed drives chipmaking time and cycle time.
