摘　　要：为了研究纵扭复合振动超声加工过程中重要加工参数对磨削力动态变化的影响规律,以超声振动磨削过程中产生的磨削力大小为研究对象,采用纵扭复合振动超声磨削加工工艺方法,搭建测力系统试验平台,研究不同加工参数下磨削工程氧化锆陶瓷材料产生的磨削力变化规律,试验结果发现:外加超声振动在一定程度上能强化磨削能力,减小磨削力,取较大进给速度和磨削深度会增大磨削力,使得磨削力波动明显,而主轴转速增大则会显著减小磨削力的产生。In order to study the influence of important machining parameters on the dynamic change of grinding force with longitudinal-torsional vibration ultrasonic machining,the grinding force produced during ultrasonic vibration grinding is studied.By using longitudinal-torsional composite vibration ultrasonic grinding technology,a force measuring system test platform is built to study the grinding force variation law on grinding engineering zirconia ceramics usingr different processing parameters.The experimental results show that the ultrasonic vibration can enhance the grinding ability and reduce the grinding force in a certain extent,and the larger feed speed and grinding depth will increase the grinding force and make the grinding force fluctuate obviously,while the increase of spindle speed will significantly reduce the grinding force.
