Abstract: 
ultrasonic vibration grinding differs from traditional grinding in terms of its material removal mechanisms. The randomness of grain-workpiece interaction in ultrasonic vibration grinding can produce variable chips and impact the surface roughness. However, the correlation between surface roughness and the undeformed chip thickness (UCT) is unclear. In this study, a symbolic difference method is proposed to calculate the interference depth and width between the grain and workpiece. The thickness distributions of variable undeformed chips are obtained to describe the stochastic interaction characteristics. Meanwhile, the thickness distribution characteristics of undeformed chips under different grinding parameters are analyzed. Then, a surface roughness prediction model is established based on the undeformed chip thickness distribution. Finally, the correctness of the model is verified by experiments. The prediction values are in good agreement with the experimental results.
