Abstract
This paper presents a technique for machining advanced ceramics with liquid nitrogen (LN) cooled polycrystalline cubic boron nitride (PCBN) tool. A LN circulation system has been designed to control the cutting tool temperature. The tool wear of PCBN50 during the machining of the reaction bonded silicon nitride (Si3N4) reduced significantly with LN cooling. The surface roughness due to LN cooling assisted cutting was about six times better than normal cutting.
