Z axis)
XA, ZA Starting point of blank (only effective if no blank was
programmed):
 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 Displays which workpiece spindle is used to process the
cycle (machine-dependent)
 Main drive
 Opposing spindle for rear-face machining
