Procedure
420
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.
This error message appears when chamfering would be possible through the reduction of
the immersion depth ZFS.
This error message appears when the tool would already damage the edges during
insertion. In this case, the chamfer FS must be reduced.
