● The adjustment sequence of the probe (calibration) is controlled via the "tool measuring"
The internal sequence is the same as in measuring. The measuring results, however, are
stored in the data for the probe triggering points - not in the tool offsets.
Note
The internal NC programs for measuring or calibrating are configured so that measuring is
carried out with the rising edge of the probe.

JOG mode is selected. The measuring feed is entered. The probe is calibrated or the precise
measuring trigger points are entered.

and "tool calibration" softkeys and the opening window. The tool used in this case is the
calibration tool with precisely known and entered dimensions.
The calibration tool for the milling technology is of "cutter" type, and for turning it is of
"turning tool" type with a cutter radius of zero. The entered cutting edge position is not
taken into account in this case.
measuring" softkey and further softkeys.
HMI by pressing the "tool measuring" softkey. PLC can specify a different T number to
the active one via the IS "T number for tool measuring in JOG" (VD1900 5004). If the
probe switches when the selected axis is traversed, NCK outputs the IS "Probe 1 active"
(V27000001.0). The PLC then sets IS "Feed disable" (V3200 0006.0) and NCK stops the
axis movement. Feed disable is maintained as long as a traverse key is depressed in
JOG and the IS "Measuring in JOG is active" (V1700 0003.7) is set. After this the PLC
outputs the IS "Reset" (V3000 000.7). The traverse movement in JOG is thereby
cancelled.
command "AUTOMATIC mode" (V1800 0000.0) after the traverse key has been released
(immediately after handwheel jog). PLC transfers this to the NCK (V3000 0000.0).
AUTOMATIC mode is set to active by the NCK (IS "Active mode AUTOMATIC" (V3100
0000.0)) and is displayed in the HMI screen. PLC cancels the IS "Feed disable (V3200
0006.0). The HMI then outputs the IS "Mode change disable" (V1800 0000.4) to the PLC.
If the PLC recognizes this signal (is only applied for one PLC cycle), the PLC outputs the
IS "Mode change disable " (V3000 0000.4) to the NCK.
An NC measuring program has been loaded to the NCK by the HMI. This is activated
now. The automatic direction of approach to the probe and the traverse path including the
safety clearance is calculated in this measuring program.
The HMI outputs the command to start the measuring program to the PLC via the IS
"Start measuring in JOG" (V1800 0000.6). The signals in the V1800 area are only applied
for a single PLC cycle. The IS "Start measuring in JOG" is therefore stored intermediately
in the PLC. The NC measuring program is launched by the PLC by outputting the IS "NC
START" (V3200 0007.1) to the NCK.
