Machining is an important aspect in the field of manufacturing in order to shape the metal into required form and to get the good dimensional tolerances. Any machining process involves three basic elements viz., chip, cutting tool and work piece, in which the cutting tool is one of the major considerable factors. It is the ability of the cutting tool to shear the unwanted material form the work piece. It not only meant for the shearing the metal but also to achieve the required accuracy. These tasks can be performed efficiently when the cutting tool severs for a long period of time, which determines the rate of production and in turn governed by the number of times that a tool must re-grinded or reconditioned. The efficiency of the cutting tool not only enhances the productivity but also minimizes the cost of reconditioning of tool. Therefore there is a need to enhance the performance of the cutting tool and is measured as the time taken between two successive grindings which defines the cutting tool life. Knowledge on various machining parameters and tool failure mechanisms that affect the tool life is vital. Many globally reputed manufacturing organization of cutting tool with their rich experience of research and development, invented different ways of enhancing the life of cutting tool in order to optimise the rate of the production and to reduce the cost of production, which is highly acceptable to the manufacturing industry. To optimize the service life of a given tool, failures must be minimized in all manufacturing steps going into its production and its proper use must be ensured. A register of tool failures covering the full range of failure sources can therefore contribute significantly to a tool service life improvement and hence, to more efficient manufacturing. The main objectives for improving the cutting tool life are enhancing the productivity, reducing the manufacturing cost and to maintain the same accuracy till the end of the machining. This paper is devoted towards studying the effects of machining variables on tool life and various tool failure mechanisms.
