Tool wear in cutting carbon fiber reinforced polymer/ceramic matrix composites: A review

Carbon fiber reinforced resin/ceramic matrix composites are multiphase materials composed of fiber, interface and matrix. They are increasingly in demand for applications in aerospace, energy, sports, transportation and other fields because of their excellent mechanical properties. However, their non-homogeneous and anisotropic properties cause rapid tool wear during machining, which reduces machining efficiency and aggravates machining damage such as delamination and burr. It seriously restricts the further application of composite materials. A comprehensive understanding of wear mechanism is required to control the tool wear rate in composite machining. However, there is a lack of review of tool wear behavior in composite machining. The present work is focused on the research advances in tool wear issues when machining carbon fiber reinforced resin/ceramic matrix composites. The wear mechanism of carbide, coating and polycrystalline diamond tools under different machining conditions is expounded. Methods for characterizing tool wear are compared. The effect of tool wear on machining quality is summarized. Finally, the development trends and future research content of the tool wear problem are discussed.
