Machining type
● Roughing
During roughing, the individual planes of the rectangular pocket are machined one after
the other from the center point until depth Z1 is reached.
● Finishing
During finishing, the edge is always machined first. The rectangular pocket edge is
approached on the quadrant that 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.
● Chamfering
Chamfering involves edge breaking at the upper edge of the rectangular pocket.

Note
The following error messages can occur when chamfering inside contours:
● Safety clearance in the program header too large
This error message appears when chamfering would, in principle, be possible with the
parameters entered for FS and ZFS, but the safety clearance then could not be
maintained.
● Immersion depth too large
This error message appears when chamfering would be possible through the reduction
of the immersion depth ZFS.
● Tool diameter too large
This error message appears when the tool would already damage the edges during
insertion. In this case, the chamfer FS must be reduced.
