Actual Problems in Machine Building. Vol. 10. N 1-2. 2023 Innovative Technologies in Mechanical Engineering ____________________________________________________________________ 12 computers and devices for electrical modeling of temperature fields. As already mentioned, the electrical simulation method is based on the similarity of differential equations describing the processes of heat propagation in a solid and the passage of electric current in a conducting medium. There is an analogy between temperature and electric potential, intensity of heat flow and current density, amount of heat and amount of electricity, etc. Combining theoretical studies with experiments and modeling, A.N. Reznikov managed to solve a complex of complex problems of thermal physics of scientific and practical interest. Conclusions To level the shortcomings of the coolant, several options were considered: cutting temperature measurements with reduction and elimination of coolant use. In order to meet the requirements of modern CNC machining, reducing, measuring and controlling cutting temperatures is critical to optimize the cutting process. Therefore, it is very important to develop new technologies by actively integrating these three functions. It is promising to develop an easy-to-use and accurate method for measuring and reducing cutting temperature during machining in real time using a closed cooling system. References 1.
