Measuring
In-process measuring
A touch-trigger probe is a prerequisite.
Application example: With in-process measurement you can monitor
tool wear. If you use the tool life monitoring, worn-out tools are
identified as such and the CNC PILOT replaces it.
Example: In-process measuring
Switch on in-process measurement G910
G910 activates the probe and the probe monitoring function.
Programming:
„ Position the probe at a sufficient distance before the measuring
point.
„ Program G910 alone in the NC block. G910 is modal
„ Program G1 .. as follows:
„ Target position is at a sufficient distance behind the measuring
point
„ Activate a per-minute feed rate (G94)
. . .
N.. T.. Insert the touch probe
N.. G910 Activate in-process measurement
N.. G0 .. Pre-position the touch probe
N.. G912
N.. G1 .. Move the touch probe to the workpiece
N.. G914 G1 .. Retract the touch probe
