Abstract: Carbon fiber reinforced ceramic matrix composites (Cf/SiC composites) have the advantages of good chemical and thermal stability, high specific strength, high temperature resistance and low density. They are widely used in aerospace, high-speed trains and nuclear energy. Currently, ceramic matrix composites (CMCs) components are generally prepared by near net forming technology. However, secondary machining is still required to meet the dimensional accuracy and geometric tolerance of the final assembly. Owing to the characteristics of Cf/SiC composites such as anisotropy and multiphase heterogeneity, the need for efficient and low-damage machining of Cf/SiC composites is concerned. Hence, the research progress of ultrasonic vibration-assisted milling (UVAM) technology for Cf/SiC composites reported in the literature are systematically reviewed. Firstly, the research status of traditional machining and special energy field assisted machining technology of CMCs are summarized. Secondly, the material removal mechanism and ultrasound action mechanism are summarized using the orthogonal cutting tests and finite element simulation during UVAM of CMCs. Then, the modeling method of cutting force of CMCs in UVAM is discussed, and the research on machined surface damage and residual strength of CMCs is introduced. Finally, the development trend of UVAM of CMCs and the outlook on future research directions are analyzed.
