摘要
在超声波复合振动机理的基础上，分别对纵向振动和两种横向振动组成的Ⅰ型、Ⅱ型超声波复合振动的加工特性进行了较系统的试验研究．研究结果表明：Ⅰ型超声波复合振动可以对未烧结陶瓷等非导电限性材料的异型孔穴、窄槽进行高效加工，而Ⅱ型超声波复合振动适用于对上述材料进行精细加工．
The mechanism of ultrasonic compound vibration machining is described. Detailed ex-perimental investigations have been carried out on the machining characteristics with ultra-sonic compound vibration of type Ⅰ and type Ⅱ which are composed of the same longitudinalbut two different transversal vibrations respectively.The type Ⅰ ultrasonic compound vibra-tion is suitable for rough machining with a machining efficiency higher than that of type Ⅱultrasonic compound vibration and a cutting ratio as high as 250 m3/min·mm(-1). The typeⅡ ultrasonic compound vibration is suitable for precision machining. When cutting non-sin-tering ceramics,a thin wall of 0. 1 mm in thickness can be obtained.
