Completing and generating the Corner Finishing toolpath

In the Corner Finishing strategy dialog:

1. Select the Corner finishing page and:
   1. From the Output list, select Both. This creates two separate toolpaths for steep and shallow regions.
   2. Enter a Threshold Angle of 65. This specifies the angle, measured from the horizontal, that determines the split between steep and shallow portions of the surface slope.
   3. Enter a Cusp of 0.01. This defines the maximum allowable cusp height. The stepover between tool passes is automatically calculated from this value and the geometry of the tool and part.
   4. From the Cut direction list, select Any. This uses both the Climb and Conventional methods of milling.
2. Select the Corner detection page and:
   1. Select 8 Ball_LS_THfrom the Reference tool list. The Corner Finishing toolpath makes a comparison between the current and previous tools, and automatically machines the corners that the previous tool was unable to access.
   2. Enter an Overlap of 0.5. This indicates how far the toolpath is extended beyond the borders of the unmachined region. It is also used as the overlap value between the steep and shallow portions of the toolpath.
   3. Enter a Detection limit of 165. This specifies the angle at which PowerMill finds corners. Only corners less than the specified angle are machined.
3. Click Calculate to generate the toolpath.

   Progress is shown on the Status bar at the bottom of the screen. The generation may take a minute or so, depending on the processing power of your PC.

4. After the toolpath is generated, Close the strategy dialog.
