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.
