摘要：

Based on the study of the motion characteristics of a single abrasive particle under two-dimensional ultrasonic vibration，the average chip thickness was determined according to the principle of constant volume. Based on the geometric shape of the abrasive grain and the elastic recovery rate of the material，the chip deformation force model is derived. According to the friction force from the elastic contact between the abrasive particles and the workpiece and the chip outflow，the friction model is established. Considering the impact of high frequency vibration on the total grinding force，the impact force model is obtained. Combining the chip deformation force， friction force and impact force model， the grinding force model of two-dimensional ultrasonic grinding is obtained. Through the experimental study of two-dimensional ultrasonic grinding of alumina ceramic materials，the constants in the model are determined，and the rationality of the grinding force model is verified. The results show that the average errors between the experimental values and the theoretical values of the normal force and the tangential force are 11. 09% and 8. 07%，respectively，and the maximum error does not exceed 20%. Thus，the model has a predictive effect. © 2024 Northeast University. All rights reserved.
