Measuring Cycles for Milling and Machining Centers
5.2 CYCLE971 tool: Measuring milling tools, drills
This sequence applies to
_TP[_PRNUM-1, 7]=133 or _TPW[_PRNUM-1, 7]=133:
probe in Z axis can only be calibrated in minus direction, X, Y, in both directions.
Value _TP[k, 7] or _TPW[k, 7] =133 is the default value.
If some axes or axis directions on the probe cannot be approached the value must be
changed.
Significance:
Decimal point
Value
Example _TP[k, 7]=123:
X in both directions,
Y only in plus direction,
Z can only be calibrated in minus direction.
It must always be possible to approach the tool axis (applicate, for example, Z axis for G17)
in the minus direction. Otherwise, automatic calibration is not possible.
The sequence described above changes according to the value of _TP[k, 7] or _TPW[k, 7].
Position after end of measuring cycle
On successful completion of the calibration process, the calibration tool is positioned
distance _FA above the center of the probe.

0: axis not possible
1: only minus direction possible
2: only plus direction possible
3: both directions possible
