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:

    • Value of the geometric property Max Enclosed Circle Diameter

    • Value of the geometric property Min Enclosing Circle Diameter

    • 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:

    • Value of the geometric property Max Enclosed Circle Diameter (approximate diameter of the workpiece at the point of cut)

    • 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.
