Measurement and analysis of cutting forces on single point cutting tool in turning of MS bar with dry condition and rust-X cutting fluid

Abstract

Purpose – The purpose of this paper is to measure the effect of rake angle on cutting forces on the rake face of single point cutting tool with two cutting conditions. The experimental setup has been developed to measure the cutting forces. The study aims to put forward the optimum cutting condition, which improves the product quality, surface finish, productivity and tool life. Design/methodology/approach – The load cell-based tool dynamometer has been developed to measure the cutting forces. The experiments have performed on the mild steel bar of hardness 60 BHN. The friction and the normal forces have measured in dry cutting condition and with rust-X cutting fluids. The cutting forces for these two cutting conditions have calculated with constant depth of cut, speed and feed with different rake angles in the range of degrees 6, 7, 8, 9, 10, 11, 12, 15 and 20. Findings – The experimental observations shows the variations of friction and normal forces with different cutting conditions and parameters. It shows the friction force on rake face increase and the normal force on the rake face decreases with increase the rake angle. Research limitations/implications – The observations has done only for mild steel of hardness 60 BHN. It can also be perform on different materials and for different cutting conditions. Practical implications – The experimental setup developed in this research can be used in the manufacturing industry. It can help to decide and maintain the optimum cutting conditions. Originality/value – The observations have been made on an experimental setup, which fulfills the actual working/cutting conditions as per the use in industries.
