Measurement repetition after violation of dimensional difference and safe area
_CBIT[0]=0:
_CBIT[0]=1:
Alarm and M0 for measurement repeat with _CBIT[0]=1
_CBIT[1]=0:
_CBIT[1]=1:
392
Feed and speed in CYCLE971
0: calculation by measuring cycle itself
1: set by user in array _MFS[ ]
Deletion of values from the measuring cycle arrays in GUD6
0: No deletion
1: delete _TP[ ], _TPW[ ], _WP[ ], _KB[ ], _EV[ ], _MV[ ],
_CBIT[13]
Length reference of the workpiece probe in milling measuring
cycles
0: length relative to probe ball center
1: length ref. to ball circumference
Transfer of workpiece probe data into the tool offset in
CYCLE976
0: No acceptance
1: result of probe ball calculation on calibration will be entered in
the geometry memory of the workpiece probe (radius)
Calibration monitoring for "Measuring in automatic mode" can
be activated/deactivated with this!
0: No calibration monitoring
1: Calibration monitoring active
When the parameters for the dimensional difference (_TDIF) and safe area
(_TSA) are exceeded, the measurement is not repeated. An appropriate alarm is
displayed.
When the parameters for the dimensional difference (_TDIF) and safe area
(_TSA) are exceeded, a measurement is repeated. An alarm is also displayed in
the repeat measurements if _CBIT[1] is set.
no alarm, no measurement repetitions in M0
If the limits of the parameters for the dimensional difference and safe area are
exceeded, M0 is generated and the repeat measurement must be started with
NC-START. An alarm that does not have to be acknowledged is displayed in the
alarm line.
