Analysis of Cutting Forces for Different Work Materials and Tool Material: Effect of Rake Angle in Turning Process

Ashutosh Verma, Prof. Suman Sharma

Abstract :

The aim of this work is to study experimentally the influence of tool rake angle, work piece material type and tool material on the main cutting force during a turning process. EN 31, MS, Aluminum specimens have been used as work piece materials, High Speed Steel and Carbide tools are used as tool materials. The experiments have been obtained with constant cutting speed (550 rpm), depth of cut and feed rate with five different tool rake angles (00-160). For the estimation of the material type influence on the main cutting force, the experiments have been performed with the same cutting conditions, tool characteristics on the three work piece materials and two tool materials. The effect of the tool rake angle on the main cutting force depends on the type of work piece material, i.e. for EN 31, M.S. specimens the main cutting force has a decreasing trend as the rake angle increases from 00 to 160 but for the Aluminum specimen the main cutting force was increased as increasing the tool rake angle. The experimental results show that main cutting force has the maximum value at the EN 31 specimen, average value at the MS specimen and the lower value at the Aluminum specimen. In this experiments HSS and Carbide tool have been used, the value of cutting force is more in carbide tool than HSS tool for same cutting conditions.
