Research on wear mechanism of carbide tool for high-speed cutting aluminum alloy

In the high-speed cutting process of aluminum alloy turbine by carbide tools, the wear characteristics of carbide tools directly affect the service life and machining accuracy, resulting in that the machining accuracy cannot reach the design requirements. In addition, the serious wear may lead to the damage of tools and parts. The carbide tools used for high-speed cutting aluminum alloy turbine were investigated in this paper, the four-factor three-level orthogonal tests were used to studied the wear performance of carbide tools. The wear state and microstructures of carbide tools were observed and analyzed in different cutting parameters. The improvement measures were discussed and proposed to effectively control the tool wear. In the results, the improvement measures can ensure the machining accuracy of parts, and have the practical value to popularize.
