The Steeps Z (Horizontal Hill) Finishing is a toolpath method, which can be used as a re-finishing operation that is applied after a Parallel Finish operation. In this cut method, the cutter is restricted to machine areas in the part that are steeper than a user specified angle from the horizontal XY plane. Once the system identifies these regions then a Parallel Finish type of machining is employed to machine these regions.

Optionally, you can specify to cut only those regions that were not properly machined by the previous Parallel Finish operation. These regions would be steep areas in the part that were parallel to the cutting angle of the previous operation. In this case the toolpath will only be created in the regions that are steeper than your defined angle and parallel to the previous cut direction.
