Abstract: A study has been made in identifying and isolating effects of cutting conditions on cutting forces. Machining tests were conducted using sharp tool and the effects of cutting parameters were studied. In the presented study experiments were conducted on EN8 steel at different cutting parameters. Here chatter starting point length is measured from the free edge of the work piece. Experiments were conducted on a precision center lathe and the influence of cutting parameters was studied using DOE. Based on the main effects plots obtained through full factorial design, optimum level for surface roughness and cutting force were chosen depth of cut, and the interaction of feed and depth of cut significantly influenced the variance. In case of surface roughness, from the three levels of cutting parameters considered Linear regression equation of cutting force has revealed that feed, the influencing factors were found to be feed and the interaction of speed and feed. As turning of EN8 steel using HSS is one among the major machining operations in manufacturing industry, the revelation made in this research would significantly contribute to the cutting parameters optimization.
