Machining type
You can select the machining mode for milling the rectangular pocket
as follows:
Roughing
In "Roughing" mode, the individual planes of the pocket are
machined one after another from inside out until depth Z1 or X1 is
reached.
Finishing
In "Finishing" mode, the edge is always machined first. The pocket
edge is approached on the quadrant which joins the corner radius.
In the last infeed, the base is finished from the center out.
Edge finishing
Edge finishing is performed in the same way as finishing, except
that the last infeed (finish base) is omitted.
Anfasen
Beim Anfasen wird die Kante am oberen Rand der Tasche

If you want to mill a chamfer and the corner radius was R = 0 during
finishing, you must specify the radius of the finishing milling tool in
parameter R during chamfering.
