Laser-Assisted Milling of silicon nitride ceramic: a machinability study

International Journal of Mechatronics and Manufacturing Systems (IJMMS), Vol. 1, No. 1, 2008

Abstract: The machinability of silicon nitride ceramic under Laser-Assisted Milling (LAMill) is presented in this paper. The effect of temperature on cutting force was analysed. Chips were observed under optical microscope to understand the material removal mechanism. Surface integrity was examined. Tool wear and workpiece edge chipping were measured under different temperatures. When combining high temperature and blunt exit angle, macroscale exit edge chipping can be completely eliminated. It was found that laser heating could significantly improve the machinability of silicon nitride ceramics by reducing cutting force, increasing tool life and reducing workpiece edge chipping.
