Ultrasonic Vibration-Assisted Cutting

Ultrasonic vibration machining is a kind of efficient precision machining technology, and this chapter investigates in detail the key problems of ultrasonic vibration in the machining process. Firstly, the cutting principle of ultrasonic vibration is systematically introduced, and its mechanism and advantages are deeply elaborated. Secondly, the ultrasonic vibration horn is analyzed in depth, and the structural design of the horn and its influence on the cutting performance are discussed. For the ultrasonic vibration cutting force and cutting temperature, explored its changing law, analyzed the ultrasonic vibration on these two key parameters of the influence mechanism, for the optimization of processing parameters to provide a theoretical basis. In addition, the study of residual stress was carried out, and its sources and influencing factors were analyzed. In terms of surface quality, the influence of ultrasonic vibration was evaluated and analyzed, and its influence law on surface morphology was summarized. Finally, through experimental verification and data analysis, the tool wear was discussed in depth, and the influence of ultrasonic vibration on tool life and effective methods to extend tool life were analyzed. These research results are of great significance in the field of ultrasonic vibration machining and provide a useful reference for further research and application.
