Paper Abstract

On-machine laser unequal-path interferometry is used for setting the zero-point of the tool path in a single point diamond turning (SPDT) lathe. Experiments have been performed to determine the accuracy of such a technique, with the aim of using it to close the control loop. This would permit the complete tool-setting cycle to be performed under CNC control, and would result in significant man-power cost reductions. Also described is a novel form of optical system which uses the advantages of SPDT to create a zoom high power laser beam expander which is permanently aligned, has in-built reference planes and which has no moving dioptric components.
