Abstract

This paper describes the development of a novel three-axis vibrating micro-scale probe for micro-CMMs. The probe is vibrated in three axes, in order to address the problems inherent with micrometre and nanometre scale co-ordinate measurements caused by surface interaction forces. These surface forces have been investigated and a model developed that describes an ideal probing situation. The vibration amplitude and frequency required for the probe to overcome the surface interaction forces have been calculated using this model. The results of initial vibration experiments are reported and the suitability of the device to counteract the surface interaction forces is confirmed.
