7. If the undercut will require multiple depth passes then go to the Parameters Tab, and click on Multiple Steps.

8. Next select the Defined depth and call out the thickness of you tool as your Depth of Cut.

9. After this point go to the Leads Tab and select a lead that is appropriate so that the tool doesn’t plunge into the undercut. (Typical leads are parallel with at least half the diameter in length)
