“…Inter-diffusion between cobalt in the tool and iron in the steel and decarburization of the tool has been reported as the major diffusion reactions that occur [26,27]. According to Jiang and Xu [28], the tool wear process can be divided into five stages: initial stage of wear, regular stage of wear, micro breakage stage, and fast wear stage and tool breakage. Other studies have divided the tool wear process into three stages in which rapid flank wear occurred at the beginning of machining at cutting speeds of 200250 m/min, followed by a gradual and steady wear growth, and finally by an accelerated wear towards the point of tool rejection [29].…”

-As we know the cutting tool is an important basic tool required in metal removal operations for producing the components. It not only produces component but also maintains the dimensional accuracies, geometrical tolerances and desired surface finish of the machined part. Machining is important in metal manufacturing process to achieve near-net shape, also for the aesthetic requirements. The latest machining process and using the CNC machine tools the cutting tool play a vital role. The manufacturers of these components expect to improve their productivity, quality of the components and longer life of the cutting tools. The longer life of the cutting tool depends on various factors like machine tools used for the machining operation, cutting conditions, work piece material hardness and tool wear etc. In order to meet all these tasks the cutting tool manufacturers in the process of producing quality tools to withstand for higher cutting forces, thermal resistivity with more wear resistance. Many reputed cutting tool manufacturing organisations globally with their rich experience of research and development, invented different ways of enhancing the life of cutting tool in order to optimize the rate of production and to reduce the cost of production, which is highly accepted by the manufacturing industry. The continuous inventions in developing cutting tool materials and coatings on these materials in improving the wear resistance of the cutting tool is in progress day by day. One of the main pre-requisites for successful industrial production is the use of quality coated cutting tools with defined mechanical and technological properties. Therefore, for the development and introduction of new coated cutting tool (new combination of cutting material and hard coatings), it is necessary to carry out a number of studies with the purpose to optimize the coatings composition and processing procedures, and also to test new tools in working conditions.The requirement from the manufacturing industry is produce faster, better, safety and more ecologically, force us to develop new effective tools and innovative technologies. This provides a technological challenge to the scientists and engineers and increases the importance of knowing several scientific disciplines In this paper the analysis is made for the performance of various coated carbide cutting tools in machining the steel AISI 1018. In this review, the machining performance of coated tungsten based cemented carbides, were investigated during finish turning of AISI 1018 steel under dry conditions.
