Conventional composite cutting tools and methods are well suited for thermoset composites. The defects of layering, tearing, burrs and the like are easily generated in the cutting process, and the processing quality is not easy to ensure; the abrasion of the cutter is aggravated by the rebound of high-hardness fiber materials and powder cutting; the difference between the thermal expansion coefficients of the matrix and the fiber material is large, and residual stress is easy to generate in processing; the cutting chips exist in a dust form, the processing environment is severe, and a special chip removal system is needed; and the process is not suitable for use with thermoplastic composites. The thermoplastic composite material is a composite material which can be melted by heating, and the problems of material sticking, serious cutter loss, poor trimming quality and the like caused by a large amount of cutting heat easily occur by using a traditional machining mode. The development of the composite material in China in the field of aerospace is severely limited by processing tools, processing modes, processing efficiency, processing quality and the like. In recent years, with the explosion of thermoplastic composite materials, further research on new machining techniques has been focused.
