摘　　要：对硬脆性材料实行旋转超声振动磨削加工,可以有效改善加工表面质量。分析了在旋转超声振动磨削过程中单颗磨粒的运动特性与加工表面质量的关系。在旋转超声振动磨削过程中,旋转振动磨削的周期往复作用及切削速度增大、作用时间缩短等运动特性,使得表面质量和加工精度得以提高。从工件的动态位移情况来看,在旋转超声振动磨削中,表面粗糙度有所降低,工件振动系统的刚性有所提高,这也有助于提高加工表面质量和精度。Hard and brittle materials are processed with rotary ultrasonic vibration grinding in order to improve their surface quality effectively. In the process of rotary ultrasonic vibration grinding, the relationship between motion characteristics of single abrasive and machined surface quality is studied. The surface quality and machining precision will be improved because of the periodic reciprocating action of rotary vibration grinding, the increase of cutting speed and the shortening of acting time. At the same time, the dynamic displacement of the artifact is analyzed, and it is proved that the roughness of the machined surface is decreased and rigidity of the vibration system of the artifact is improved in vibration grinding, so the quality and precision of the machined surface can be improved.
