You can cut undercut regions with either an Isoline operation or a Flowline operation.
To machine undercut regions, you must.
- Create an Isoline or Flowline operation.
- Select an appropriate side mill cutter. FeatureCAM does not automatically select side mill cutters.
- Specify a Horizontal lead-in/out plane on the Leads tab. You may also have to experiment to determine an appropriate Ramp diameter to prevent gouging.
