Ultraprecision Ductile Cutting of Glass by Applying Ultrasonic Vibration

Abstract

Summary Ultraprecision ductile cutting of glass is realized by applying ultrasonic vibration to a single crystal diamond tool in the cutting direction. It is clarified by grooving experiments that the critical depth of cut for ductile cutting is increased and the surface profile of diamond cutting edge is better transferred to the cut groove as compared to the conventional Cutting. The transparent surface of soda-lime glass with surface roughness of 0.03 μm Rmax is obtained by face turning. The work is considered as a contribution to the ultraprecision machining of brittle materials.
