NCG CAM has rest area machining options on all the finishing routines, such as waterline, raster, spiral, radial, constant step-over, parallel pencil passes, corner offset passes, morphed and boundary passes.

This allows the input of the previously used cutter size or reference cutter to be specified. Passes will only be generated in areas that are inaccessible to the reference cutter. All rest area calculations can be done without the need for boundaries, and steep and shallow cutter contact angles can be applied.
