Longitudinal-torsional coupled rotary ultrasonic machining of ceramic matrix composites:evaluation of cutting force

摘要：

　　This Study was devoted to developing a novel rotary ultrasonic machining(RUM)method by applying longitudinal-torsional coupled(LTC)vibration for hole-manufacturing of ceramic matrix composites(CMC)that are known as most difficult-to-cut materials.The LTC-RUM was accomplished by adding helical flutes on the diamond core tool of conventional RUM(Con-RUM)with the help of finite element analysis method.As a main indicator of processing performance,the cutting force of LTC-RUM was evaluated by comparison with Con-RUM.Experimental results showed that the LTC-RUM could dramatically reduce the cutting force compared with Con-RUM,thus enhance much higher drilling efficiency.
