Abstract: High performance materials such as hard-brittle materials and composite materials are widely used in multiple fields, mainly using diamond wire sawing technology for cutting. In recent years, with the improvement of the cutting quality and efficiency requirements, ultrasonic assisted diamond wire saw combined cutting technology has gradually developed. The ultrasonic assisted diamond wire saw combined cutting technology improves cutting efficiency and machining surface quality, prolongs the service life of the diamond wire, and is an important development direction in the future. In this paper, the research status of ultrasonic assisted diamond wire saw combined machining technology is summarized from the processing principle, processing quality and influencing factors, and the future problems and development direction are prospected.
