The study objective is to determine the rational turning modes of TN1 alloy according to the lowest friction coefficient in the cutting area. The tasks to which the paper is devoted are: to draw up an experiment plan for turning the workpiece under various cutting modes; to measure the chip thickness using Compass-3D graphic editor for each cutting mode; to calculate the values of the chip shrink factor for each of the cutting modes; to calculate the values of friction coefficient between the chip and the cutting tool; to find the dependence of friction coefficient from cutting modes; to determine the turning mode in which friction coefficient has the lowest value. To achieve this goal, experimental studies are conducted to determine the values of chip shrinkage under various cutting modes. According to the found values of the shrink factor, the friction coefficients in the cutting area between the chips and the front surface of the cutter are calculated. As a result of the research, empirical dependences are found that make it possible to calculate the value of the friction coefficient between the front surface of the cutter and the chips when turning TN1 alloy with an error of less than 1.4%. The rational modes corresponding to the lowest friction coefficient in the cutting area are experimentally determined.
