Measuring in JOG
4.2 Workpiece measurement
Result
Measurement is performed automatically at P1 with the set measuring feed as soon as you
press "NC Start". The probe probes 4 points of the inside and outside wall in succession.
After successful measurement, the measured value is stored internally and the "P1 stored"
softkey that was previously switched inactive is activated.
After manual positioning at the next center P2 and with softkey "P1 stored" switched active,
pressing "NC start" starts measurement for this hole/spigot.
The rest of the sequence is as for P1.
If all of the measuring points have been successfully completed and all "Px saved" softkeys
activated, then a vertical "calculate" softkey is displayed. After this softkey is pressed, P0
and "alpha" are calculated.
When the "coordinate rotation" angular offset (correction) is selected, then the offset is also
activated if it is the active ZO.
When the "rotary axis" angular offset is selected (name of the rotary axis), a help function for
the user is displayed to activate the offset.
Display and correction
After offset calculation has been completed, the frame components of the selected ZO are
redisplayed along with the measured "alpha" angle and the coordinates of the reference
point P0.
ZO correction is effected in such a way that the "alpha" angle determined and point P0 are at
the desired setpoints (translation and rotation) in the offset workpiece coordinate system
after activation of the selected ZO.
Note
• The rejection, repetition, and end of measurement are described in the "Reject, repeat,
• A support function is available to the user when activating the determined ZO correction
