The work is devoted to the questions of experimental estimation of the influence of the degree of the tool wear, during turning of metals in metal-cutting machines, on the level of thermal energy in the contact area of the tool with the workpiece. In the work, the experimental method revealed that with the increasing of the tool wear along the back face, the power of the released thermal energy in the contact zone of the tool and the machined part increases. This is associated with an increase in the power of irreversible pre-formations in the contact area of the tool with the workpiece, the result of which is the growth of energy consumption and the growth of conversion of this energy into thermal energy in the contact zone. The main conclusion on the work can be a conclusion about the repetition of the appearance of the dependence of the level of thermal energy in the cutting zone on time, the graph of the dependence of the degree of deterioration of the instrument on time. Proceeding from this, we can talk about the possibility of linear interpolation of the heat level from the degree of wear during the synthesis of mathematical models of the processes accompanying the cutting of metals in metal cutting machines. From the point of view of a possible explanation of this connection, it can be that with the increase of the tool wear, the capacity of irreversible transformations in the workpiece and in the tool itself grows, and the result of the growth of this capacity is the increase in the power of the heat released during processing.
