Measuring in JOG
4.2 Workpiece measurement
• Select the required angle offset:
• Under the "set angle" input, an orientation deviating from 0 degrees with respect to the
• Only for offset type "coordinate rotation" and if "set P1" is selected:
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 center is stored internally and the "P1 stored" softkey that
was previously switched inactive is activated.
After manual positioning at point P2 and with softkey "P1 stored" switched active, pressing
"NC start" starts measurement of the 2nd hole/spigot. After successful measurement, softkey
"P2 stored" is activated, and the 2nd center is stored. 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, "alpha" is 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 P1.
ZO correction is effected in such a way that the angle determined is in the required set
rotation and point P1 is in the set position in the corrected 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
