Abstract: Ultrasonic Surface Rolling Process (USRP) which combines material removal of ultrasonic machining and that of traditional rolling is a mechanical type of nontraditional hybrid machining technology. It has significant advantages in the improvement of surface integrity, anti-fatigue, corrosion resistance, and wear resistance. Since the invention of USPR, a large number of studies on processing technologies and mechanisms have been conducted. It is also extensively applied to important metal materials and key parts. In this paper, the development of the surface rolling equipment at home and abroad is firstly summarized; then, main research methods of the URSP mechanism (theoretical method, finite element method, and experimental method) are discussed, with their advantages and disadvantages pointed out; the impacts of USRP on surface integrity (including microstructure, surface morphology, microhardness, residual stress) and on fatigue resistance (including the other properties) improvement are also summarized. Finally, future research and development tendency of USRP are predicted, providing reference for the ultrasonic rolling of curved surface.

Key words: ultrasonic surface rolling process, surface integrity, anti-fatigue, surface morphology, microhardness, residual stress
