Description
Summary:This paper deals with the optimization of machining parameters in turning of AISI 202 austenitic stainless steel using CVD coated cemented carbide tools. During the experiment, process parameters such as speed, feed, depth of cut and nose radius are used to explore their effect on the surface roughness (R sub(a)) of the work piece. The experiments have been conducted using full factorial 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 feed is the most significant factor that influences the surface roughness followed by nose radius. An attempt has been made to generate to prediction models for surface roughness. The predicted values are confirmed by using validation experiments.
