7 Programming with Q Parameters
7.7 Measuring with the 3D Touch Probe During Program Run
7-12
The 3D touch probe can measure positions on a workpiece during program
run.
Applications:
• Measuring differences in the height of cast surfaces
• Checking tolerances during machining
Enter G55 to activate the touch probe.
The touch probe is automatically pre-positioned (with rapid traverse from
MP6150) and probes the specified position (with feed rate from MP6120).
The coordinate measured for the probe point is stored in a Q parameter.
The TNC interrupts the probing process if the probe is not deflected within
a certain range (range selected with MP6130).

Enter the number of the Q parameter to which the coordinate is to be
assigned, for example Q5.
Enter the probing axis for the coordinate, for example X.
Select and confirm the probing direction.
Enter all coordinates of the pre-positioning point values,
for example X = 5 mm, Y = 0, Z = –5 mm.
Conclude input.

Pre-position the touch probe manually such that it will not collide with the workpiece when it moves toward the
programmed position.
