Abstract:

Tool life is often the most important practical consideration in selecting cutting tools and cutting conditions. Tool wear and fracture rates directly influence tooling costs and part quality. For these reasons tool life is the most common criterion used to rate cutting tool performance and the machinability of materials. An understanding of tool life requires an understanding of the ways in which tools fail. Broadly, tool failure may result from wear, plastic deformation, or fracture. Cutting edges experience much higher normal and shear stresses than almost any other type of bearing surface and, at high cutting speeds, high temperature are also generated.The main goal of this thesis is to study the influence of initial tool wear mechanisms on the cutting tools. The effects of several cutting parameters, such as cutting depth, cutting velocity feed rate and yaklaşma açısı ,on the results are analyzed.
