英文摘要Ultrasonic vibration-assisted grinding (UVG) has several advantages, such as small grinding force, good surface quality, and high grinding efficiency, outperforming conventional grinding (CG). However, it is sensitive to process parameters, making optimal processing parameters crucial and a major challenge. Therefore, in this study, we introduce a model based on the AAC theory, which uses only three quantities (vibration Angle, contact Area, and influence Coefficient of adjacent abrasive particles) to assess the forces during UVG. These three quantities depend on the movement trajectory, mutual contact relationship between the workpiece and abrasive particles, and spacing between abrasive particles. The effects of these three quantities on the scratch force were examined using molecular dynamics (MD) simulations. The reduction ratios of forces (tangential and normal directions) gradually increased with increasing angle, while the differences in the force reduction ratios for the different contact areas were not significant. As the influence coefficient increased, the reduction ratio of the tangential force increased and then flattened, and the reduction of the normal force increased and then slightly decreased. Spearman's correlation analysis shows that the vibration angle has the most effect on the reduction ratio of the scratch force. And the AAC theory was verified by UVG experiments.
