Abstract

Decreasing sizes and tolerances of engineering components bring a demand for decreasing uncertainty in the dimensional measurements of these parts. Hence there is increasing need for measuring machines capable of performing dimensional and geometrical measurements at high resolution and high accuracy. We aim to develop the technique of interferometric microscopy into a tool for dimensional and geometrical measurements of component features ranging in size from a few millimeters to 5 ¿m with uncertainties as small as 1 ¿m or less. We will also integrate recently developed probe technology into a coordinate measuring machine (CMM) to produce measurements of holes with diameters as small as 0.7 mm approximately. Preliminary measurements with the interferometric microscope of the diameters and spacings of optical fibers in an optical connector show measurement reproducibility less than 1 ¿m.
