Abstract

The article deals with the results of the study focused on the pattern of the distribution of heat flows in the cutting wedge of a carbide tool during the turning of steel. The influence of the wear-resistant TiN, (TiAlCr)N, and (AlTiCr)N coatings on the thermal state of the tool has been investigated. The results of the mathematical modeling have been compared with the data obtained by a method that relates the temperature in the cutting wedge of the tool to the changes in the microstructure and hardness of the material (the Wright and Trent methods). The experimental studies of tool life of the tools with the coatings under study and uncoated tools were carried out during the turning of AISI 5135 steel. It has been found that a tool with the (AlTiCr)N coating has the longest tool life which may be associated with a rational distribution of heat flows in the cutting zone and the cutting wedge of the tool. The use of self-organising wear-resistant coatings reduces the level of temperatures in the cutting zone by 8-20%.
