Paper Abstract
A high precision contact probe for a micro/nano-CMM was developed to detect the 3D motion of the stylus tip. This contact probe is composed of a stylus with a ball tip, a suspension plate and three displacement sensors. The stylus was connected to the suspension plate, which is suspended to the probe housing by three beryllium-copper leaf springs. A 3D translation of a ball tip causing by probing force would be transferred to three Z-displacements on the suspension plate. Displacement sensors, based on the classic model of Michelson interferometer, can measure nanoscale displacement on the plate. Calibrations with a nano measuring and positioning machine (NMM) proved the typical standard deviation was less than 20 nm for both the trigger and scanning modes.
