7.7 Measuring with the 3D Touch Probe During Program Run
The 3D touch probe can measure positions on a workpiece during pro-
gram 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 pre-
position 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:
TCH PROBE 0: REF. PLANE
Select the touch probe function.
PARAMETER NUMBER FOR RESULT?
Enter the number of the Q parameter to which the coordinate is to be
assigned (in this example, Q5).
PROBING AXIS/PROBING DIRECTION?
Enter the probing axis for the coordinate (in this example, X).
Select and confirm the probing direction.
POSITION VALUE?
Enter all coordinates of the pre-positioning point values, in this
example, X = 5 mm, Y = 0, Z = –5 mm.
Conclude input.
Resulting NC blocks:

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