Abstract:
A touch-signal probe for detecting a contact to a workpiece, comprising:a probe body; a stylus support provided at a tip end of the probe body; a stylus projecting from and supported by the stylus support, the stylus having a contact portion for abutting the workpiece at a tip end thereof; and a vibrating/detecting element for vibrating the stylus at a frequency approximately identical to a natural frequency of the stylus and for detecting a change in vibration with a contact of the contact portion of the workpiece,wherein a fitting portion for fitting the probe body is formed on the stylus support;wherein an aperture is provided around the fitting portion and extending completely through the fitting portion; andwherein, the aperture allows a portion of the stylus support to deform and absorb vibration and isolate a periphery of a fitted position of the probe body from the vibration of the stylus support.
