XA, ZA: Start point blank (definition of corner point of
workpiece blank contour – evaluation only if no workpiece blank
has been defined)
XA, ZA not programmed: The workpiece blank contour is
calculated from the tool position and the ICP contour
XA, ZA programmed: Definition of the corner point of the
workpiece blank
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)
HC: Shoe brake (machine-dependent)
DF: Miscellaneous function (machine-dependent)
Type of machining for technology database access:
Roughing
Cycle run:
1 Calculate the proportioning of cuts (infeed)
2
Approach the workpiece from the Start point on a paraxial path
for the first pass
3 For descending contours, plunge into the material at a reduced
feed rate
4 Machine the workpiece according to the calculated
proportioning of cuts
5
The contour is machined according to the setting in Contour
smoothing H
6 Return and approach for the next pass
7 Repeat 3 to 6 until the defined area has been machined
8
Return to the Start point on a paraxial path
9
Move to the Tool change point according to the setting in G14
