    Fiber reinforced SiC matrix composites (FRCMC-SiC) have significant potential in aerospace application and other high temperature conditions due to their special properties such as low density, high strength, thermostability, anti-oxidation and anti-ablation. However, the application of these composites has been hindered seriously because of their poor machining characteristics. The high-quality and low-damage machining technology must be solved in the use of this kind of high hardness, high brittleness and anisotropy materials. In this paper, the recent progress on the different machining technologies of FRCMC-SiC is reviewed. The material removal mechanism, theoretical model construction, parameters optimization, defect form and surface quality control are summarized and discussed. Finally, the existing problems are discussed, and the development trend of machining technology of FRCMC-SiC in the future is also put forward.
