摘　　要：外加超声振动使得加工过程中刀具与工件间相对运动形式和材料去除效果发生改变,采用金刚砂磨头对工程氧化锆陶瓷材料进行了相同加工参数下的普通铣磨和一维超声振动铣磨对比试验,并进行一维振动铣磨单因素试验,研究加工参数(主轴转速、铣磨深度、进给速度及超声能量)对加工表面粗糙度的影响规律。实验结果表明,在同样的加工条件下,一维超声振动铣磨加工更能显著地降低表面粗糙度;且不同的加工参数组合对表面粗糙度影响规律不同,合理地选取各单因素参数能显著的降低表面粗糙度,对加工工程陶瓷材料能产生显著的工艺效果及指导意义。With the help of ultrasonic vibration,the form of relative movement and the effect of material removal between the tool and the workpiece have been changed.The contrast experiment under ordinary mill-grinding and one-dimensional ultrasonic vibration mill-grinding on engineering of zirconia ceramics using emery grinding head is carried out,as well as one dimensional vibration mill-grinding machining experiment of single factor(the spindle speed,grinding depth,feed speed and ultrasonic energy)to find out the influence on surface roughness.The experimental results show that the one-dimensional ultrasonic vibration mill-grinding processing can significantly reduce the surface roughness under the same conditions,One-dimensional ultrasonic vibration mill-grinding processing under different combinations of parameters leads to the different influence on surface roughness,and reasonable selection of parameters of each single factor can significantly reduce the surface roughness,which have more excellent effect on the machining technology of engineering ceramics and give the guidance of machining process.
