Effect of tool overhang length on turning operation using finite element model

Abstract

Turning surface accuracy and high productivity rates have become the vital determinants and both the accuracy and surface quality plays vital role. In this paper the cutting tool modeled with finet element model and for different tool overhanging lengths analytical modal has prepared. The modal and stiffness data of the tool are extracted from ANSYS software also the mode shapes were drawn. Tool overhang was selected as input and the influences of tool overhang on the stability of turning using finite element was obtained. The stability lobe diagrams corresponding to different tool overhangs different stiffness, tool frequencies and damping ratios were presented.
