Due to its characteristics as superior lightweight

high-strength

high-hardness

high-temperature properties

carbon fiber reinforced composite（ CFRP） has been widely applied in the aerospace field recently.However

with the CFRP material becoming the primary bearing structure from the secondary

the problems of machining have become increasingly prominent. In this paper

the CFRP cutting process is reviewed first

including the chip formation mechanism

cutting force and heat

tool wear

and the machining defects. The influence of cutting parameters and tool parameters on cutting force and heat

and tool wear in drilling and milling CFRP is summarized. Then

the major reasons and influencing factors of machining damage

such as delaminations

spalling and burr are analyzed. The research progress of cutting tool materials and structures is introduced. Finally

the characteristics and application of the various advanced processes of cutting CFRP

which containing helical milling hole

ultrasonic assisted machining

grinding instead of drilling are reviewed and compared. The further problems of machining CFRP are also pointed out.
