Study of the temperature generated during the cutting process during mechanical processing

Abstract

This scientific article discusses thermal phenomena that occur during the cutting process, examples of measuring the temperature of the cutting process. 4 methods of measuring the cutting temperature were proposed and the most suitable method was determined. Method 1- determine the average temperature that will be in the cutter. Method 2-artificial thermocouple method. Method 3 is a method of experimentally obtaining the temperature distribution in certain areas of the cutter. Method 4 is a method of obtaining analog or experimental data using calculations. These methods were fully reviewed, advantages were compared with disadvantages, and the most optimal method was chosen. In addition, the influence of the tool on the cutting process was noted. For example, a decrease in the proportion of heat entering the tool does not mean a decrease in temperature on the contact pads of the tool and on the cutting wedge itself. On the contrary, as the cutting speed increases, the temperature increases significantly. The influence of the material on the accuracy of the cutting process was also noted. As an example, the material of 40X steel was taken. Taking into account its thermal conductivity, the temperature deformation that occurs during the cutting process was revealed. That is, the higher the thermal conductivity of the processed material, the more heat is transferred to the workpiece. In addition, this article also talked about the impact of the intensity of tool wear.
