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

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

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
