Abstract
Metallic Nano coating on cutting tools are an effective way for improving tool performance while machining difficult to machine materials. The need for high productivity and accuracy in metal machining has leads to the development of hard coatings on the cutting tools. Traditionally hard tool materials are unable to achieve all the properties such as high hardness, low wear rate, long tool life, and good surface finish at the same time and at the highest level. In order to increase the life of the cutting tools thin hard film coating is introduced on the cutting tool. Inserts of coated with single layer of metallic nano particles (TiAlN) by magnetron sputter method. Since TiAlN coating has shown lower resistance to Tungsten carbide (WC) and less material damage than generated stiffness (24.47 GPa), according to evaluations of high-rise models.
