Zirconia ceramics is a typical hard and brittle material, which is very difficult to process. In recent years, with the rapid development of the 3C industry, zirconia ceramic materials have achieved a wide range of applications. Longitudinal-torsional ultrasonic assisted grinding (LTUAG) is efficient for processing hard and brittle materials. However, the mechanism of LTUAG of zirconia ceramic is not studied sufficiently. In this study, the spatial trajectory of the grinding grain in three different grinding methods is established and the critical cutting speed of LTUAG is calculated. Simulation model of LTUAG of zirconia ceramic is established. The results show that the longitudinal-torsional ultrasonic vibration increases the spatial trajectory length of the grinding grain, thereby reducing the thickness of the maximum removal layer and reducing the cutting force. When the cutting speed is less than the critical cutting speed, LTUAG can significantly reduce the Mises stress, the subsurface damage and the cutting force.
