氧化锆陶瓷作为一种先进的结构陶瓷，以其优异的性能逐渐应用于制造业、航空航天等领域。氧化锆陶瓷材料的去除机理比较复杂，但一般认为硬脆材料的去除是通过塑性去除和脆性去除两种方式进行的。本文采用超声波振动辅助磨削技术对陶瓷材料进行非传统加工。首先，对ZrO2陶瓷材料进行了单磨粒划痕试验。通过实验分析得出，氧化锆陶瓷材料的去除方式随载荷的增加而改变。当施加的载荷大于500 mN时，氧化锆陶瓷材料通过脆性去除而被去除。然后，在分析超声振动辅助磨削（UVAG）划痕试验和运动学的基础上，建立了超声振动辅助磨削力预测模型，并通过设计的试验验证了模型的有效性。结果表明，随着主轴转速n和振幅Aa的增大，磨削力减小。磨削力随进给量（vf）和磨削深度（ap）的增加而增加。此外，与普通磨削（CG）的磨削力相比，UVAG中的磨削力显著降低。通过实验分析，提高了工件的表面质量，减少了磨头的磨损。
As an advanced structural ceramic, zirconia ceramics are gradually used in the fields of manufacturing, aerospace and other fields with their excellent properties. However, the mechanism of material removal is complex for zirconia ceramics but it is generally accepted that the brittle-and-hard material is removed by plastic removal and brittle removal. In this paper, ultrasonic vibration assisted grinding is used as non-traditional processing to machine the ceramic materials. Firstly, a single abrasive grain scratch test was first carried out on the ZrO2ceramic materials. It can be obtained through experimental analysis that the removal mode of the zirconia ceramic material is changed with the increase of load. When the applied load is greater than 500 mN, the zirconia ceramic materials are removed by brittle removal. Then, based on analysis of scratch test and kinematics of ultrasonic vibration assisted grinding (UVAG), a grinding force prediction model is developed and the validity of the model is verified by the experiment designed. It can be found that the grinding force is decreased with the increase of spindle speed (n) and amplitude (Aa). And the grinding force is increased with the increase of feed rate (vf) and grinding depth (ap). In addition, compared with the grinding force of the common grinding (CG), the grinding force is significantly reduced in the UVAG. And the surface quality of the workpiece is improved and the wear of the grinding head is reduced in the UVAG by the analysis of experiment.
