The result proves that not only the grinding wheel's cost is lower, but also the effect is better than ordinary wheel in hardness, strength density and metallograph. The wheel has good abilitg of keeping grinding material and good grinding property. It can satisfy reguest of ELID grinding technology for wheel's selectrolytic and forming film. It is an ideal, practical and special grinding wheel of ELID grinding.

Firstly,simulation models of grinding process are built,which include the topograph of grinding wheel,the description of kinematics of grinding,grinding force,grinding temperature and wheel w...

首先建立了砂轮地貌、磨削运动的描述、磨削力、磨削温度和砂轮磨损等模拟模型。

With the aid of the experiment, crack formation and its expand pattern of ZTA ceramics under ultrasonic vibration were analyzed, its fracture criterion was established and the experiment results showed that intercrystalline fracture is the main fracture pattern of ZTA ceramics under common grinding, and transcrystalline fracture is the main fracture pattern of ZTA ceramics under TDUVAG, and the finding add to evidence showing that TDUVAG has better material removal property.

基于该方法分析具有预制裂纹的ZTA纳米复相陶瓷材料在超声振动条件下裂纹扩展方式，确立其断裂判据，通过该断裂模拟试验得出：沿晶断裂是普通磨削主要的断裂模式，而穿晶断裂是二维磨削主要的断裂模式，进一步证明二维磨削具有较好的材料去除特性。

In this thesis, experimental investigations have been done on temperature and energy partition and wheel wear in grinding with a vitrified CBN wheel.

本文对使用陶瓷结合剂CBN砂轮的磨削温度、热量分配比例以及砂轮磨损进行了试验研究，论文的主要结果如下：(1)对陶瓷结合剂CBN砂轮磨削温度的试验结果表明，陶瓷结合剂CBN砂轮的磨削温度很低，这主要是由于CBN磨料具有优良的导热性能。

They have tracking function in grinding process, and are able to autocontrol the dimension and process. They can measure, store and transmit static or dynamically for axle journal and dustproof seat information. Automatic measuring machine is adopted to inspect some dimension of the axle, instead traditional manual measuring and it is more credible.
