Machining type
You can select the machining mode for milling the circumferential groove as follows:
● Roughing
During roughing, the individual planes of the groove are machined one after the other from
the center point of the semicircle at the end of the groove until depth Z1 is reached.
● Finishing
In "Finishing" mode, the edge is always machined first until depth Z1 is reached. The groove
edge is approached on the quadrant that joins the radius. In the last infeed, the base is
finished from the center point of the semicircle to the end of the groove.
● 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 circumferential groove.

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.
