Optimization of Turning Process Parameters for EN24 Steel Alloy using Experimental Design

Abstract

The overarching aim of this work is to optimize the various process parameters involved in turning of EN 24 Steel alloy using Tungsten Carbide inserts to enhance the tool life and surface finish. Appropriate or random selection of cutting parameters have serious effect over the final output responses such as Surface Roughness , Tool life and other related properties of both the work piece and tool . Controlling the effective parameters is the need of the hour in any product manufacturing system. In the present work three different turning process parameters such as Cutting Speed, Feed rate and Depth of cut are considered for optimization study by varying them with three levels. The experimental design matrix for conducting experiments were prepared using Taguchi's Orthogonal Array and calculation of Signal to Noise ratio is done for identifying the best combination of parameters. Through ANOVA it is observed that Cutting speed is the most influencing parameter with a maximum contribution of 80.23 comparing to the other input parameters over surface roughness. The S N ratio method Smaller is Better have shown that the parameter level combination A3B1C1 2000m min, 0.05 mm rev, 0.2 mm can provide good surface finish of the material with enhanced tool life.
