My research in ultrasonic machining (USM) is centered on facilitating the precision manufacturing of hard-to-cut materials by means of high-frequency vibration. I am committed to the multi-physics field modeling of the interaction between ultrasonic waves and materials, exploring how the acoustic field, flow field, electric field, and temperature field synergize to achieve nanoscale surface finish in brittle materials (such as ceramics and semiconductors). Key interests encompass: (1) Intelligent tool design: Optimizing the geometry of the horn and the dynamic characteristics of abrasive particles via finite element analysis and machine learning. (2) Establishment of composite USM systems: Integrating rotary ultrasonic, mechanical grinding, and electrochemical processes into one processing system, involving the study of the stability of the processing system. In the academic domain, I undertake research on the processing parameters-microstructure-performance relationship in advanced composite materials, with the aim of formulating standard protocols for ultrasonic machining for industrial-scale applications.
