NX Adding Spring Passes in Hole Milling when using a Spiral Cut Pattern

A Spiral Cut Pattern is used to rough a pocket in a Hole Milling operation. What can be done to include an additional spring pass into the tool path in order to size the side wall more accurately?

Solution

1. Be certain that the Cutting Parameters -> Strategy -> Add Cleanup Passes option is turned on. This setting will cause the tool path to be extended so that all the material along the wall will be removed. The picture below shows how this setting changes the tool path.




2. Set Non Cutting Moves -> Overlap -> Overlap Distance -> Measurement to Angle and then specify how much overlap is required in degrees. A 360 degree value will cause the tool to overlap by one full turn essentially adding one spring pass. Entering a 720 degree angle will add two spring passes.
