轴向超声辅助磨削陶瓷的磨削力模型
Grinding Force Model for the Axial Ultrasonic Assisted Ceramic Grinding
摘 要
基于单颗磨粒的最大未变形切屑厚度, 建立了轴向超声振动辅助陶瓷磨削的磨削力数学模型, 模拟得到了不同磨削深度、砂轮线速度和工件运动速度下的磨削力并进行了试验验证。结果表明: 法向磨削力的计算值与试验值的误差为15%左右, 切向磨削力的计算值与试验值的误差为20%左右; 由于前后磨粒的运动轨迹会存在重合, 模型计算的磨削力比试验值大; 磨削力随着砂轮边缘速度的增加而减小, 随着磨削深度和工件速度的增加而增大。

Abstract
Based on the maximum non-deformed chip thickness of the single abrasive particle, the grinding force mathematical model of the axial ultrasonic vibration assisted ceramic grinding was established. The simulated grinding forces were obtained with different cut depths, wheel linear speeds and workpiece speeds and verified by the experiments. The results show that the error between the calculated and experimental values was about 15% of the normal forces and 20% of the axial forces. The grinding forces by calculation were higher than those of experiments due to the trajectory overlaps of the front and back abrasive particles. The grinding force decreased with the wheel edge speed increase, and increased with the increase of the cut depth and workpiece speed.
