A review of the research on the variation of tool’s motion trajectory and its influence on the formation mechanism of surface quality in ultrasonic vibration machining

Abstract

Compared to traditional machining, ultrasonic vibration machining harnesses the power of small yet high-frequency vibrations to generate distinctive relative displacements between the workpiece and the cutting tool. This significantly enhances machining efficiency and quality. One distinctive feature of ultrasonic vibration machining is its unique tool’s motion trajectory, setting it apart from conventional methods. In recent years, numerous studies have analyzed the causes and functions of tool’s motion trajectories in ultrasonic vibration machining, playing a crucial role in understanding the machining mechanism and enhancing this method. To support researchers in this field, we have compiled and organized relevant literature. This review categorizes ultrasonic vibration machining based on the form of tool’s motion trajectory, explores the influence of varying machining parameters on tool’s motion trajectory, examines specific machining conditions under intermittent separation cutting characteristics, and analyzes the impact of tool’s motion trajectory on surface morphology, chip formation, and tool wear. In conclusion, this review summarizes the research findings and provides future prospects for investigating tool’s motion trajectories in ultrasonic vibration machining. As a nascent machining technique, ultrasonic vibration machining still faces challenges in various aspects. Addressing these challenges through the exploration of tool’s motion trajectory changes may offer potential solutions. Therefore, in-depth studies on tool’s motion trajectory hold significant importance in advancing the development of ultrasonic vibration machining.
