You can select the machining mode for milling the longitudinal slot as
follows:
•
Roughing
During roughing, the individual planes of the slot are machined
one after the other until depth Z1 is reached.
•
Finishing
In "Finishing" mode, the edge is always machined first. The slot
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.
•
Chamfer
Chamfering involves edge breaking at the upper edge of the
longitudinal slot.
