Programming technological functions (cycles)

10.2 Milling

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.

Additional supplementary conditions

1/2 slot width W ≤ milling cutter diameter

● Edge finishing

Finishing allowance UXY ≤ milling cutter diameter

● Chamfering

The tip angle must be entered into the tool table.
