Analysis of Single Point Cutting Tool of a Lathe Machine Using FEA

The geometry of cutting tool surfaces is one of the crucial parameters affecting the quality of manufacturing process and has been traditionally defined using the principles of projective geometry. The parameters of geometry defining the various cutting tool angles are described by means of taking appropriate projections of the cutting tool surfaces. Development in the field of computer Aided Geometric Design(CAGD) now provide more elegant approach for specifying the cutting tool surfaces as a set of biparametric surface patches. This study of machining processes involves analyzing the chip formation process. Years of research has conclusively shown that it a process involving plastic deformation in which large strains and strain rates are developed by localized shear deformation of work material immediately ahead of tool. Heat generated during the chip formation process as a result of plastic deformation and friction. The heat influences chip shape, tool wear, surface finish and cutting forces.
