Chamfering machining
Chamfering involves edge breaking at the upper edge of the circular pocket.
Figure 9-5
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.
