The friction behavior during the cutting of TC4 titanium alloy by single abrasive grain and its impact on polishing process were studied through finite element simulation software.The Abaqus software was used to establish a plastic deformation model during the cutting of TC4 titanium alloy by single abrasive grain,and the iterative adaptive mesh remeshing technology was applied to accurately simulate the contact stress distribution and plastic deformation under different friction coefficients,which provided a theoretical basis for optimizing the polishing process of TC4 titanium alloy blades.The analysis results reveal the impact of friction coefficient on the cutting depth and material pile-up ratio,especially during the cutting-out stage of the abrasive grain,the increase in friction coefficient significantly promotes the accumulation of material at the front end and both sides of the abrasive grain,so it is important to control the friction coefficient in actual polishing process.
