摘要：基于超声辅助微磨削加工对Al2O3/TiC陶瓷材料进行微磨削试验，并与传统微磨削技术进行对比。利用单因素分析法研究Al2O3/TiC陶瓷材料的磨削力随超声振幅、磨削砂轮转速、磨削深度、进给速度等工艺参数的变化规律，为提高加工质量和合理选择加工参数提供依据。结果表明：超声波辅助微磨削试验获得了不同磨削参数下磨削力的变化规律，磨削力随超声波振幅、主轴转速的增大而减小，随磨削深度、工件进给速度的增大而增大；在相同工艺参数下，相比传统微磨削加工，超声辅助微磨削Al2O3/TiC陶瓷材料可以有效降低磨削力；在保证工件加工表面质量的前提下，超声辅助微磨削加工可以采用较大的磨削深度和磨削速度，有助于提高材料的去除率和加工效率，试验还得出加工Al2O3/TiC陶瓷材料的最优参数组合。

Abstract:Based on ultrasonicassisted microgrinding，the microgrinding experiments of Al2O3/TiC ceramic materials are carried out and compared with the traditional microgrinding technology.The variation of the grinding force of Al2O3/TiC ceramic materials with ultrasonic amplitude，grinding wheel speed，grinding depth，feed rate and other technological parameters is studied by single factor analysis method，which provides the basis for improving the processing quality and selecting the processing parameters reasonably.The results show that the grinding force decreases with the increase of ultrasonic amplitude and spindle speed，and increases with the increase of grinding depth and the workpiece feed rate.Compared with traditional microgrinding，ultrasonicassisted microgrinding can effectively reduce the grinding force.On the premise of ensuring the surface quality of the workpiece，ultrasonicassisted microgrinding can adopt greater grinding depth and speed，which is helpful in improving the material removal rate and processing efficiency.And the optimal parameter combination in grinding Al2O3/TiC ceramic materials is obtained.
