An ability to predict the tool life during machining is necessary for the design of cutting tools and the determination of cutting conditions and tool change strategies. The extensive research in this area during the past century or so has contributed greatly to our understanding of the problem. However, there is as yet no machining theory to provide adequate relationships between tool life and cutting conditions, tool geometrical parameters and, work and tool material properties. Some of the major difficulties are: (i) the complexity of the machining process which involves extreme conditions of very high strains, strain-rates and temperatures, and (ii) lack of suitable data. Moreover, tool life depends on a number of variables which include the machine tool, tool material and geometry, work material and cutting conditions. In this paper, the wear mechanisms of cutting tools made of carbide are to be investigated while machining HDS material. The tool cutting feed, spindle speed and depth of cut has a great influence on tool wear rate and tool life. In this thesis, different parameters of tool cutting feed, spindle speed and depth of cut are to be analyzed to optimize the parameters so that the tool wear is reduced and tool life is increased. In this project we consider only maximum and minimum parametric conditions.
