Abstract

A contract sensing system is provided for a coordinate measuring machine which is manually operated. The system provides a control over the level of the sensing force of a work piece against a probe of the machine. The system also provides an instantaneous signal corresponding to the initial contact of the contacting force for avoiding displacement of the probe whereby the accuracy of the measurement is improved.
