Ultrasonic assisted grinding (UAG) is an outstanding combined processing technology suitable to machine hard brittle materials such as advanced ceramics. During UAG, the effect of ultrasonic vibration on grinding process is determined by matching performance of ultrasonic vibration and grinding parameters. However, it is still lack of deep study. In response to this problem, a single abrasive tool is adopted to conduct UAG and conventional grinding (CG) tests on polished surface of SiC. Through comparison of grinding force, grinding force ratio and scratch morphology, the effect of ultrasonic vibration on grinding process along with changing grinding parameters is analyzed. The results show that the grinding force and grinding force ratio produced by UAG are lower than those produced by CG under the same conditions. In addition, the grinding scratch morphology produced by the single abrasive presents significant hammering and intermittent characteristics when grinding parameters are low. However, the hammering is weakened evidently and intermittent grinding tends to disappear with increasing grinding parameters. Accordingly, the difference of grinding force between UAG and CG decreases significantly, i.e., the matching performance between ultrasonic vibration and grinding parameters get worse.
