4.8 Milling cycles
Figure, axial
Select milling
Select figure, axial
Depending on the parameters, the cycle mills one of the following
contours or roughs/finishes a pocket on the face:
 Rectangle (Q=4, L<>B)
 Square (Q=4, L=B)
 Circle (Q=0, RE>0, L and B: No input)
 Triangle or polygon (Q=3 oder Q>4, L<>0)
