This work presents a mathematical modeling process of the rotary turning by a numerical method, which allows to research the dynamics of the temperature distribution in the workpiece and cutting tool during processing. Proposed methodology also allows to define the optimal cutting mode during the rotary turning for processing of the durable wear resistant cast iron ICH300Х18G3. For performance of the study, from among the many existing models of fracture during the cutting, the criterion, which was first proposed by prof. V.L. Kolmogorov. In order to increase the productivity of calculations, a mathematical model was proposed where only three objects were used: a cylinder-shaped workpiece and a cutting tool and tool shaft. The work considered the coefficient of friction between the cutting insert and the workpiece, taken equal to 0.29 and in addition, the dynamic coefficient of 0.39. To define the temperature in the objects, objects were separately selected. As a result, the temperature values were taken for different objects. Despite the fact that the occurring phenomena are non-linear, the results showed that by increasing the cutting conditions, it is possible to increase the distribution of temperature and on the contrary, the process is controlled. The results of the research have shown the management possibility of the thermal processes during the process by enumerating technological parameters.
