Due to the development of new materials and the increasing demands of productivity in the last decades, cutting tools become increasingly exposed to higher thermal loads. To meet the requirements of modern machining processes, a wide variety of cutting tools is coated, which significantly increases their thermal stability. In recent years, several authors investigated the thermal load of coated cutting tools. Depending on the process, a contrary significance of the thermal insulation effect was reported. Therefore, this study investigated the impact of the coating’s thermal insulation effect in continuous turning of AISI 4140. The temporal dependence of temperature load was analyzed by a newly developed FEM based simulation model. It was shown that the thermal insulation effect decreases significantly with process duration.
