The aim of this work is to find the effect of tool rake angle experimentally on work piece material and tool material on the basis of main cutting force during a turning process of EN 31Steel, MS, Aluminium specimens have been used as work piece materials and carbide as a tool material. The experiments have been obtained with continuous cutting speed, feed rate and depth of cut with five different tool rake angles (00-160). For the estimation of the material type effect on the primary cutting force, the no. of tests run has been performed with the same cutting conditions, tool characteristics on the three Specimen materials and tool material.
The influence of the tool rake angle on the main cutting force will depend on the type of work piece material, i.e. for EN 31, M.S. specimens the main cutting force has a reducing pattern as the rake angle increases from 00 to 160 but for the Aluminium specimen the main cutting force was increases with the increasing the tool rake angle. The experimental results show that main cutting force gets the uppermost value at EN 31 specimen & average value at the MS specimen and the low value at the Aluminium specimen. In this thesis we are also finding optimal control parameters to achieve the minimum Surface roughness. It will investigate the process parameters, cutting speed, feed rate and depth of cut on cutting parameter during turning operation. Mainly surface roughness where investigated employing Taguchi's design of experiments with different turning process parameters of EN-31 Steel, MS, Aluminium in turning operation with rake angles of 40 and optimized by S/N ratio.
