摘要： 以氧化铝和氧化锆两种工程陶瓷在高效磨削条件下的磨削振动和表面波纹度为研究对象，概述了磨削表面波纹度的定义和评价方法以及产生波纹度的原因，在超高速平面磨削实验台上进行磨削工艺试验，通过改变砂轮线速度、进给速度和磨削深度，分析了磨削参数对零件表面波纹度的影响。在试验研究的基础上，对磨削表面波纹度的影响因素和机理进行分析和讨论。试验结果表明，在陶瓷材料高效平面磨削中，砂轮线速度和进给速度是影响磨削颤振与表面波纹度的主导因素。在如120 m/s的较高砂轮线速度时，磨削过程振动主要是由强迫振动引起，工件表面质量好于低速情况。在保证较高磨削效率的前提下，陶瓷材料的高效磨削更适合在大切深和小进给速度条件下进行。

Abstract: Taking grinding vibration and surface waviness of two engineering ceramics, namely alumina and PSZ, under high efficiency grinding as research target, definition and evaluation method of grinding surface waviness and the reason of surface waviness are briefly described. Influence of grinding parameters on component surface waviness is analyzed through changing wheel speed, feeding speed and grinding depth on the platform of ultra-high speed surface grinder. On the basis of experimental research, the affecting factor and principle of grinding surface waviness are analyzed and discussed. The results indicate that, in high efficiency surface grinding of engineering ceramics, wheel speed and feeding speed are the dominant factors that affect grinding vibration and surface waviness. In the condition that wheel speed is 120 m/s, grinding vibration is mainly triggered by forced vibration sources, and the machining surface quality is better than that of lower wheel speed. Under the condition that the grinding efficiency is guaranteed, high efficiency grinding of engineering ceramics is more suitable to be taken in larger depth and lower feeding speed. 
Key words: engineering ceramics    high efficiency grinding    surface waviness
