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
To activate the touch probe, press the TOUCH PROBE key. You preposition
the probe, which then automatically probes the specified position.
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 MP 6130).
To program the use of a touch probe:

measured
Enter the number of the Q parameter to which the coordinate is to be
assigned (in this example, Q5).
Enter the probing axis for the coordinate (in this example, X).
Select and confirm the probing direction.
Enter all coordinates of the pre-positioning point values, in this
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.
