Optimization of Process Parameters in Turning using Taguchi Method

The aim of this work is to find the effect of tool rake angle experimentally on work piece material on the basis of main cutting force during a turning process of EN 31Steel, MS, Aluminium specimens. 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). The influence of the tool rake angle on the main cutting force for EN 31, M.S. specimens the main cutting force has a reducing pattern as the rake angle increases but for the Aluminium specimen the main cutting force increases with increasing the tool rake angle. The experimental results show that main cutting force gets the maximum value at the EN 31 specimen, average value in 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 cutting parameters of EN-31 Steel, MS, Aluminium of turning parameters with rake angles of 40 and optimized by S/N ratio.
