Abstract: This study examined the temperature that develops in the tool cutting process during rough turning on an experimental basis by using a model for the polycrystalline cubic boron nitride (PCBN) tool. The cutting tool temperature has significant effect on the future performance of a tool and the quality of its machined component and is therefore important to explore. The thermal conductivity of the PCBN tools was determined at room temperature by utilizing the transient plane source (TPS) method for the binderless cBN (BCBN) and CBN500 grades. From the testing, it was determined that they both possessed high thermal conductivities of 110 and 190 W/m K, respectively.
