Abstract

Optical systems based on the focus variation technique are able to collect surface topography measurements from machined parts at high speed and a considerably lower cost than a contacting coordinate measuring machine (CMM). This paper presents a preliminary study of probing characteristics of a focus variation instrument within a single field of view, following the guidance of the international standard ISO 10360-8 (a recently published standard for acceptance and reverification testing of CMMs which use optical distance sensors). The selection of test samples and test strategies is also discussed, with specific emphasis on the adaptations made to the ISO 10360-8 guidance to realise accurate measurements.
