G845—Milling
You can change the milling direction with the cutting direction H,
the machining direction Q and the direction of tool rotation (see
following table). Program only the parameters given in the following
table.

Parameters—Milling
ID
Milling contour—name of the contour to be milled
NS Starting block no. of contour
 Figures: Block number of the figure
 Free closed contour: A contour element (not starting point)
B Milling depth (default: depth from the contour description)
P (Maximum) infeed (default: milling in one infeed)
XS Milling top edge—lateral surface (replaces the reference plane
from the contour definition)
ZS Milling top edge—face (replaces the reference plane from the
contour definition)
I Oversize in X direction (radius)
K Oversize in Z direction
U (Minimum) overlap factor. Defines the overlap of milling paths
(default: 0.5).
Overlap = U*milling diameter
V Overrun factor (no effect with C-axis machining)
H Cutting direction (default: 0)
 0: Up-cut milling
 1: Climb milling
F Feed rate for infeed (default: active feed rate)
E Reduced feed rate for circular elements (default: current feed
rate)
RB Retraction plane (default: back to starting position)
 Front or rear face: Retraction position in Z direction
 Lateral surface: Retraction position in X direction (diameter)
Q Machining direction (default: 0)
 0: From the inside out (from the inside towards the outside)
 1: From the outside in (from the outside towards the inside)
