中文摘要：
对纳米复相陶瓷在二维超声振动条件下的材料去除率进行了理论分析，建立了超声磨削下材料去除率的数学模型，利用MATLAB软件进行了相应的定量计算分析，表明在一定的条件下，超声磨削的材料理论去除率一般是普通磨削的5倍以上.通过去除率试验发现，超声磨削的材料去除率仅是普通磨削下的1.1 }4.3倍，分析了产生这种现象的原因，同时对理论与试验结果的材料去除率随磨削参数的变化趋势做了分析和比较，发现变化趋势基本一致，说明建立的数学模型具有一定的合理性.
英文摘要：
The material removal rate in two-dimensional ultrasonic grinding was analyzed theoretically and the mathematical model of material removal rate was established.The quantitative calculation was first carried out by using MATLAB and the conclusion that ultrasonic grinding material removal rate generally was more than 5 times as that in ordinary grinding under certain conditions.By a removal rate test,there was the conclusion that the ultrasonic grinding material removal rate generally was 1.1~4.3 times higher than that under ordinary grinding,and the reason for this phenomenon was analyzed.At the same time,the results of the experiment and theoretical analysis were used to analyze the change trend of material removal rate with the grinding parameter.Theoretical results are in a good agreement with the actual situation.
