| With the ultrasonic machining technology, the intermittent processing of a workpiece relies on the instantaneous high frequency vibration impact. Despite a small macro cutting force, due to its extremely strong cutting capability, the technology is mainly used in the precision processing of hard and brittle materials to improve the processing accuracy and surface quality. Firstly, the basic principle and application scope of ultrasonic machining technology were expounded. Secondly, the research progress of ultrasonic assisted cutting technology was summarized. Afterwards, the establishment and validation of the model for ultrasonic assisted milling net cutting were emphatically presented, along with a discussion on the effects of processing parameters on tool trajectory and workpiece surface quality. The reasons why elliptical vibration cutting could effectively restrain cutting chatter were explained. The various effects of ultrasonic assisted grinding technology on the surface quality and temperature distribution of the workpiece surface in the processing of both metallic and non-metallic materials were discussed. Later, the resulting cutting force and feed speed of ultrasonic assisted drilling technology versus regular drilling parameters were summarized. In addition, the recent development directions of ultrasonic machining technology were introduced, including the three-dimensional (3D) elliptical ultrasonic vibration cutting technology, ultrasonic ELID composite grinding technology, ultrasonic EDM composite processing technology, working principle of ultrasonic assisted polishing, latest research trends and experimental results to be achieved. Finally, the current researches on ultrasonic machining technology and ultrasonic assisted or composite technology were summarized. |
