Abstract

This paper presents the current state of a project at the National Physical Laboratory (NPL) aimed at developing a vibrating tactile probe for miniature co-ordinate measuring machines (CMMs). Current probing technology is limited by several factors including; the reduced size of parts to be measured, the use of novel and delicate materials for manufacturing, and the need for lower uncertainties on measurements. The solution developed at NPL is a novel, silicon-free MEMS assembled with a sphere tipped micro-stylus. The mechanical design and modelling of this device are reported along with a description of the manufacturing routes, assembly solutions developed, operation and testing methods. The preliminary results from experimental testing are presented and prove that this probe is also capable of operating in a non-contact mode. Tests have been performed in both vertical and lateral directions.
