Effect of Rake Angle on Chip Control in CNC Lathe Machining of Low Carbon Steel

Abstract

This paper aims to ingenuity of the machining of low carbon steel in order to control chip length and reduce cycle time of the component, to improve surface finish by increasing Rake angle. This approach is used to reduce hazard to the operator. Surface roughness is measured by digital dial gauge. Heat generated during the turning operation is measured by using thermocouple. It gives clear perception about the rake angle. Parameter levels are adjusted according to insert grade to handbook and discussed about the efficient coolant flow condition. This paper reviews various machining parameters which affect turning operation of low carbon steel. Such as insert geometry, coolant flow, heat dissipation, depth of cut, spindle speed, feed rate.
