See also: Rest Finishing Cycle
The Rest Finishing cycle produces a toolpath that only machines the region where material has been left by a previous machining cycle.
The range to be machined is defined as the areas that cannot be machined by a tool of a given radius. The toolpath will collapse from the outer edge of this region, producing a toolpath that maintains a constant stepover in 3D from one pass to the next. This generates an even surface finish. Note that the toolpath will not ride up vertical walls.
If multiple rest areas are detected, the toolpath will be machined one region at a time, in height order with the highest first.
The Pencil Trace option allows you to machine a final pass along the centre line of the machined area. It only be applied to regions that would normally be found by the Pencil Mill cycle and can be used to help clean up any cusps.
Please note that this cycle is restricted to ballnose tools.
