Optimization of Machining Parameters in Steel Turning Operation by Taguchi Method

This work is optimization of machining parameters in steel turning operation by Taguchi method. In this study the experimental work was carried out by turning EN-31 steel alloy by using tungsten carbide inserts. There were three main purposes of this study. The first was to explain and demonstrate a systematic procedure of Taguchi parameter design and applying it to the data on turning. The second was to find out the optimal combination of process parameters based on S/N ratio and to know the significance of each parameter by performing ANOVA analysis. The third important aim was to find out the effect of lubricant temperature in steel tuning process on the response (i.e surface roughness). The cutting parameters namely feed rate, depth of cut, and lubricant temperature were varied to observe the effects on responses. The main conclusion drawn from this study is that better surface finish is obtained by applying cooled lubricant. Even with higher depth of cuts surface finish is improved if lubricant temperature is lowered. (C) 2012 Published by Elsevier Ltd.
