Abstract：In order to study the effect of different ultrasonic vibration directions on the zirconia ceramics mill-grinding process, workpieces were put to exert vibrations parallel or perpendicular to the feed direction, respectively. The machining process of abrasive particles was analyzed theoretically based on an indentation fracture mechanics model, then the grinding experiments with different parameters were carried out and the machined surfaces were detected and analyzed. The results show that when applying the parallel vibration, the axial force (Fz) and the material removing rate(MRR) of the workpiece are higher than those under the vertical vibration assisted. However, the surface roughness (Ra) of the workpiece is smaller in the vertical vibration mode. Within the studied processing parameters, the vibration direction is the most significant factor affecting surface roughness. Furthermore, the main material removal mode in the machining assisted by vibrations in these two kinds of directions is different.
