Abstract
In the work-contacting probe head (or on the suspension of the deflectable work-contacting probe head) of a coordinate measuring machine, an electromagnet is provided to trigger a mechanical impact blow or vibration if the switch-contact circuit in the three-point mounting of the probe pin remains open for a predetermined short period of time after completion of a cycle of coordinate measurement of a given work-contacted measurement location. The delivery of the impact is sufficient to overcome any residual mechanical friction that may have interfered with return of the probe to its calibrated at-rest position, at completion of the measurement cycle.
