Abstract
Ultrasonic-assisted machining technology, with its high-frequency dynamic cutting characteristics, can effectively suppress tool wear, enhance heat dissipation in the contact zone, and reduce material damage, thereby improving surface quality and performance. In recent years, research on ultrasonic-assisted machining devices and techniques has advanced rapidly, establishing it as a widely recognized high-performance and sustainable machining method for difficult-to-cut materials in both academia and industry. This paper reviews the development of ultrasonic-assisted grinding (UAG) technology and summarizes research progress on surface integrity and service performance, focusing on: material removal and surface generation, thermo-mechanical effects and residual stress formation, micro-structure evolution and surface damage, grinding-induced surface friction and wear behavior, surface wettability, hydrophobicity, and anti-icing properties, fatigue performance and failure mechanisms of ground surfaces. The key findings of domestic and international scholars in the field of ultrasonic-assisted grinding surface integrity and service performance were systematically summarized. Additionally, this paper discussed the critical challenges and unresolved issues in current UAG technology and provides insights into future research directions. The comprehensive analysis presented here offers theoretical and technical guidance for further advancements in ultrasonic-assisted machining, promoting technological development and the enhancement of machining surface quality and performance.
