Abstract

A touch probe for a coordinate measuring machine with a processor which is programmed to generate a trigger signal signalling a contact between a stylus of the probe and a workpiece, whenever one of a plurality displacement signals exceeds a corresponding threshold. In addition, or in alternative, a delayed trigger is generated based on a processing a plurality of samples of displacement signals that are stored in a buffer. The processor is programmed to minimize anisotropy of the probe response. Furthermore, the thresholds can be modified during operations based on commands received from the CMM controller.
