4.8 Milling cy
cles
Face milling
Select milling
Select the "Face milling" cycle
Depending on the parameters, the cycle mills the following contours
on the face.
 One or two surfaces (Q=1 or Q=2, B>0)
 Rectangle (Q=4, L<>B)
 Square (Q=4, L=B)
 Triangle or polygon (Q=3 or Q>4, L<>0)
 Circle (Q=0, RE>0, L and B: No input)
Cycle parameters (first input window)
X, Z
Starting point
C Spindle angle (C-axis position)
X1 Diameter of figure center
C1 Angle of figure center (default: Spindle angle C)
Z1 Milling top edge (default: starting point Z)
Z2 Milling floor
Q Number of edges
 Q=0: Circle
 Q=1: One surface
 Q=2: Two surfaces offset by 180°
 Q=3: Triangle
 Q=4: Rectangle, square
 Q>4: Polygon
L Edge length
 Rectangle: Length of rectangle
 Square, polygon: Edge length
 Polygon: L<0: Inside circle diameter
 Circle: No input
B Width across flats:
 For Q=1, Q=2: Remaining thickness (remaining
material)
 Rectangle: Width of rectangle
 Square, polygon (Q>=4): Width across flats (use only for
even number of surfaces; program "B" as an alternative
to "L")
 Circle: No input
