Abstract: Touch trigger probe is one of the important components in On-Machine
Measurement (OMM) system, whose pre-travel value would be reckoned in the measured results
and has an influence on the inspection accuracy, so the pre-travel calibration must be carried out
to compensate the measured value under the actual conditions accurately. Based on the analysis
of the pre-travel generation causes, a novel pre-travel calibration method of touch trigger probe
is proposed, in which the contact status between probe and workpiece is detected, and the
displacement variation of the probe relative to the workpiece within the period between the
contact time and the probe triggering time is measured, so that the pre-travel value is calibrated.
The effects of various factors, such as the servo system error, geometric error and movement
error of the machine tool, the roundness error of the probe sphere and the manufacturing error
of the artifact, on the calibration accuracy are eliminated effectively. The pre-travel value of a
certain high-precision probe was calibrated under actual conditions, and according to the
calibration results the pre-travel compensation experiment of the touch trigger probe was carried
out. The experiment results show that the calibration method is feasible and effective, can be
implemented conveniently and has high calibration accuracy; and the On-Machine Measurement
accuracy could be improved obviously.
