Abstract

The diagonal measurement method has been recommended by many standards such as B5, for a quick check on the volumetric performance of machine tools. However, for large aspect machine tools, it is insensitive to the axes with short travels. A new diagonal measurement method, a sequential three axes movement and data collection method, has been developed to provide information on the two short axes in a single diagonal measurement. The Laser Doppler Displacement Meter (LDDM), that makes this method practical, performs like a Laser interferometer but with a single aperture for the exit Laser beam and the return Laser beam. The single aperture Laser makes
