OPTIMISATION OF CUTTING PARAMETERS DURING CNC TURNING OF AISI 304 AUSTENITIC STAINLESS STEEL

Abstract

In this study, the effect of important parameters of machinability like material removal rate and surface roughness were studied. optimization of machining parameters in turning of AISI 304 austenitic stainless steel using cemented carbide tools. During the experiment, process parameters such as speed, feed and depth of cut are used to explore their effect on the surface roughness (Ra) and Material Removal Rate(MRR) of the work piece. The experiments have been conducted using Orthogonal Array(OA) (Taguchi) design in the Design of Experiments (DOE) on Computer Numerical Controlled (CNC) lathe. Further, the analysis of variance (ANOVA) was used to analyze the influence of process parameters and their interaction during machining. From the analysis, it is observed that the Speed is the most significant factor that influences the surface roughness followed by feed and Depth of cut. The optimum cutting speed the impact of cutting speed, Feed and Depth of cut on Material Removal Rate(MRR) and surface roughness have been studied during turning an AISI 304 austenitic stainless steel using cemented carbide cutting tools.
