Title: Design and development of a step-gauge calibration system

Biography

Abstract

A step-gauge, consisting of several short gauge blocks fixed on a base, is widely used in the calibration of machine tools and co-ordinate measuring machines (CMMs). The step-gauge calibration system is developed by comprising a laser interferometer and a CMM. The laser interferometer was used as the standard for traceability of length measurement and designed as a two-path interferometer system to decrease the Abbe error, and then integrated with the high-precision CMM, consisting of the moving platform and probing system to implement the calibration procedure for step gauge.
