Abstract
During the turning process, a considerable amount of the machine energy is transformed into heat near the surface of the cutting insert. Almost all the technical and economical problems of the process are directly or indirectly caused by the generation of this heat. In the past few years, tool inserts have been coated with materials that provide minor wear with thermal insulation features, aiming to increase the tool life. Determining the cutting temperature during the turning process is one of the most important factors to understand the turning tool performance. Thus, it is important to develop efficient methods to determine this temperature. This work proposes to simulate the heat phenomenon, in transient regime, of a cutting tool considering the presence of the coating, convection and radiation. The results showed the coating effect for different coating thickness values. Numerical and experimental results are compared to validate the methodology.
