Measuring Cycles for Milling and Machining Centers
5.4 CYCLE977 workpiece: Measure hole/shaft/groove/web/rectangle parallel to axes
Parameters
_SZO
_MA
_KNUM
_TNUM
_TNAME
_DLNUM
_TENV
The following additional parameters are also valid:
_VMS, _CORA, _TZL, _TMV, _TUL, _TLL, _TDIF, _TSA, _FA, _PRNUM,
_EVNUM, _NMSP and _K.
_CORA only relevant for monodirectional probe. With _TSA, the diameter or width is
monitored for "tool compensation". The other parameters must also be assigned if _KNUM=0
because they refer to the workpiece.
