In order to obtain special turning tools for nickel-based superalloys with excellent cutting performance,finite element simulation and cutting experiments were used to study the influence on cutting force and cutting temperature of nickel-based superalloy GH4169 during cutting caused by the groove angle,groove gap and groove width of the linear texture grooves on the rake face and back face of the turning tool.The simulation results show that the rake face groove can reduce the cutting force and cutting temperature of the tool;compared with the groove space and the groove width,the groove angle has a more significant effect on the cutting force and cutting temperature of the tool;when a groove-like texture is parallel to the main cutting edge on the rake face of the tool with a groove space of 60 μm and a groove width of 20 μm,the cutting force is lower and the cutting temperature is the lowest.At the same time,the wear resistance and cutting life of the texture tool parallel to the cutting edge are the best,compared to non-grooved tool life,the cutting life is increased by 66.7%.
