9.3 Measuring Workpieces with a 3D Touch Probe
Measuring with the 3D touch probe during program run
The 3D touch probe can measure positions on a workpiece during
program run.
Applications:
l
Measuring differences in the height of cast surfaces
l
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 control interrupts the probing process if the probe is not deflected
within a certain range (range selected with MP 6130). Upon contact, the
position coordinates of the probe are stored in the parameter 0115 to
0119. The values in these parameters do not include the stylus length

or radius.
