Core Research Themes
Ultrasonic Micro/Nano Fabrication
Our research spans ultrasonic device development, fabrication processes, and functional applications at the micro- and nanoscale. We develop devices with self-sensing capabilities for cutting forces and vibration trajectories, alongside ultrasonic chiseling, scribing, and imprinting processes. By investigating the relationships between process parameters, surface structures, and functional performance, we aim to enable precise and efficient fabrication of surfaces for structural color, enhanced heat dissipation, catalysis, and sensor applications.
Ultrasonic Forming and Fabrication
We explore ultrasonic-assisted forming and additive manufacturing for powder composites and organic materials. Our research includes the compaction of copper–diamond powder mixtures and ultrasonic 3D printing of materials such as PDMS and resins. We investigate how ultrasonic energy influences powder rearrangement, densification, material flow, and interfacial bonding. By connecting processing conditions with the resulting structures and properties, we aim to improve forming quality, geometric control, and functional performance.
Ultrasonic Precision Machining
We investigate how ultrasonic vibration can improve the machinability of challenging engineering materials, including NiSi alloys, silicon carbide–reinforced aluminum composites, and titanium alloys. Our work examines tool–material interactions, material removal mechanisms, and surface formation under ultrasonic excitation. Through process design and parameter optimization, we aim to reduce machining forces and surface damage, control tool wear, and achieve greater dimensional accuracy and surface integrity.
Intelligent Ultrasonic Manufacturing Systems
We develop intelligent ultrasonic manufacturing systems that integrate cutting force self-sensing, automatic resonance frequency tracking, digital twins, and robotic micro/nano fabrication. Our research investigates how the dynamic performance of machining equipment and robotic platforms evolves under changing operating conditions. By combining physical modeling, process monitoring, and adaptive control, we aim to coordinate ultrasonic vibration and robotic motion, maintain machining stability, and improve manufacturing accuracy and consistency.
