P: Feed depth (default: total depth of one infeed)
FZ: Approach feed (default: active feed rate)
E: Reduced feed for circular elements (default: active feed rate)
O: Roughing/Finish – Only for pocket milling
0: Roughing
1: Finishing
H: Mill cutting direction
0: Up-cut
1: Climb
U: Overlap factor – defines the overlap of milling paths (default:
0.5) (range: 0 to 0.99)
Overlap = U * milling diameter
U = 0 or no input: Contour milling
U > 0: Pocket milling – Minimum overlap of milling paths = U
* milling diameter
JK: Contour milling – Input is evaluated only for contour milling
0: On the contour
1: Within the contour
2: Outside the contour
JT: Pocket milling – Input is evaluated only for pocket milling
0: From the inside out
1: From the outside in
R: Apprch angle (default: 0)
R = 0: Contour element is approached directly; infeed to
starting point above the milling plane—then vertical plunge
R > 0: Tool moves on approaching/departing arc that
connects tangentially to the contour element
R < 0 for inside corners: Tool moves on approaching/
departing arc that connects tangentially to the contour
element
R < 0 for outside corners: Length of linear approaching/
departing element; contour element is approached/departed
tangentially
RB: Return plane
SCI: Safety clearance in the working plane
SCK: Safety clearance in infeed direction
Further information: "Safety clearances SCI and SCK",

MT: M after T: M function that is executed after the tool call T
MFS: M at beginning: M function that is executed at the
beginning of the machining step
MFE: M at end: M function that is executed at the end of the
machining step
WP: No. of spindle – Displays which workpiece spindle is used
to execute the cycle (machine-dependent)
Main drive
Opposing spindle for rear-face machining
BW: Angle in the B axis (machine-dependent)
CW: Reverse the tool (machine-dependent)
