Abstract: To meet the manufacturing industry's demand for improving the turning efficiency and reducing the processing cost of 27SiMn steel, this paper focuses on the wear characteristics and life prediction of cemented carbide tools. A finite element simulation model of the cutting process is established by constructing the friction coefficient model of the tool-workpiece contact interface, the constitutive and failure criterion models of 27SiMn steel, and the heat conduction model. The wear rate prediction model of cutting tool is established based on the experimental data of cutting, and the coupling between the interface program and the finite element simulation is realized to simulate the wear state of the tool face accurately. A tool life prediction model incorporating cutting speed, feed rate, cutting depth and material property parameters is developed by adopting the orthogonal experimental design method. Experimental verification shows that the error between the simulation predicted values and the measured values is less than 9.1%. The research results provide a quantitative technical solution for the high-efficiency machining of 27SiMn steel and possess engineering significance for promoting the digitalization and intellectualization of the metal cutting field.
