Measuring Cycles for Milling and Machining Centers
5.4 CYCLE977 workpiece: Measure hole/shaft/groove/web/rectangle parallel to axes
The probe is already calibrated. Arrays for
workpiece probe 1: _WP[0, ...]
The following is entered under T9, D1 in
the tool offset memory:
Tool type (DP1):
Length 1 - geometry (DP3):
Radius - geometry (DP6):
Length 1 (L1) must refer to the center of
the probe ball (_CBIT[14]=0), as for
calibration.
Careful when positioning! Radius R in
length (L1) is ignored.

;ZO, select tool as probe ...
;Insert probe,
;activate tool offset
;Position probe in X/Y plane at setpoint web
center
;position in X and measurement position Y
;Position Z axis above web
;Set parameter for measuring cycle call
;with ZO and without tool compensation,
;note negative prefix for _ID!
;Probe lowered in Z axis!
;Measuring variant with ZO calculation has
been
;selected (MVAR=X1xxx) because web center
;is to be monitored (with _TSA),
;but KNUM=0: without running
;the ZO calculation and ZO compensation
;Call measuring cycle
;Traverse up Z axis
