New knowledge about possible relationships between the tool-chip contact characteristics and both the contact mechanics and thermodynamics at the interface, with special attention to the orthogonal cutting when dry end turning using natural contact tools treated with some heat isolating coatings, is developed. In order to evaluate the dependence of the contact loads, the contact temperature and frictional energy dissipation on the tool-chip contact length experimental investigations were carried out. In addition, the contact length was examined in terms of the thermal conductivity of work materials at the temperatures measured. Moreover, the combine effect of the thermal conductivities of both work and tool materials expressed by the energy partition coefficient was estimated. As a result, the interface behavior for various process parameters versus the contact length was analyzed. Two different types of tool coatings with improved heat isolating properties, in combination with carbon and stainless steels, were tested. It is pointed out that the results obtained provide a systematic explanation of the role of the contact length in controllability of such process outputs as contact temperature, contact stresses, heat partition and frictional power intensity.
