Abstract: For the excellent physical, chemical and mechanical properties of fiber reinforced composites, they are widely used in high-tech fields such as aerospace, automobiles, and new energy. Compared with traditional drilling and milling tools, less defects are generated when machining holes of fiber reinforced composites by abrasive tools, such as delamination, burrs, tearing and thermal damage after processing, especially, fiber reinforced ceramic matrix composites with higher hardness could be stably processed when using abrasive tools. In this paper, hole making mechanism of grinding fiber reinforced composites is reviewed, including chip formation, grinding axial force, grinding temperature, and so on. And then, the research status of hole making defects and their evaluation methods are discussed. Subsequently, hole-making quality and its influencing factors are analyzed. Besides, the abrasive tools for grinding fiber reinforced composite holes and their wear mechanisms are summarized. Finally, the development trends of grinding holes for fiber reinforced composites are concluded and forecasted.
