Due to the high cutting temperature during the highspeed cutting of aluminum alloys, the tool wear is severe, which reduces the tool life and machining accuracy. Therefore it is important to accurately predict tool wear and analyze tool wear rules. The research progress of the tool wear theoretical model was summarized from the tool life model and the tool wear rate model, and the tool wear law was analyzed based on the cutting parameter, tool nature and cooling method. On the basis of the current research, about highspeed cutting of aluminum alloys, tool wear increases with the increase of the cutting speed and feed rate, there is no obvious rule of cutting depth; common tool wear includes adhesion wear, abrasive wear and diffusion wear, among which adhesion wear is the main tool wear mechanism.
