Experimental Investigation of Process Parameters on Machining Force, MRR and Power in Turning of AISI 316 Steel

Abstract

A machining process involves many process parameters which directly or indirectly influence the surface quality of the product. A precise knowledge of these optimum parameters facilitate reduce the machining costs and improve product quality. Current investigation aims to investigate the effect of process parameters; cutting speed, feed and depth of cut in turning of SS-316 which is widely used in automobile industries, each varying in three levels. The response characteristics considered for study were machining force, material removal rate and power. Experiments were planned according to Taguchi full factorial design using L27 orthogonal array. The machining was carried out using cemented carbide cutting tool and various forces acting on the cutting tool were measured using lathe tool dynamometer. Results indicated that cutting speed and tool feed rate have a significant effect than that of depth of cut on the quality characteristics.
