Stress Analysis Criteria of High Speed Steel Single Point Turning Tool

Abstract — High speed steel (HSS) is a material usually used in the manufacture of machine tool bits and other cutters. In this paper, certain tool geometry (6-8-10-10-20-45-0.6) is taken and a cutting tool is been made by considering other parameters. Accordingly a 3d model of the tool is been made in finite element software package ANSYS-10. The model is used to investigate the effective and shear stresses on the HSS tool. Detailed results of the cutting forces generated during the machining process are presented and a comparison has been made with the experimental results for a range of feeds. The final goal of the system is the generation of cutting forces and then the von Mises equivalent stress contours are generated in ANSYS after importing the tool model in parasolid format from solidworks and after applying cutting forces to the centre of pressure region. Solution is done keeping displacement fixed to 0 at the side of the dynamometer. Free meshing is done in this 10 noded element tool. The vulnerable region of the tool is identified by von misses stresses
