Abstract
The Last few years there is tremendous research in machining and development in technology. According to present scenario about competition growth in the market and to attain high accuracy now a days the non-conventional machining are become lifeline of any industry. One of most important non convectional machining process is plasma arc cutting process. This paper presents an experimental analysis on the optimization and the effect of the cutting variables on Material Removal Rate (MRR), Kerf Width (KW) and Surface Roughness (Ra) in Plasma Arc Cutting (PAC) of EN19 Material using Taguchi L9 orthogonal array method. Four process parameters i.e. Gas pressure, Current, cutting speed and Arc gap have been selected for the experimental work. Analysis of variance (ANOVA) and Regression analysis have been performed to get effect of each variable on responses and optimization of process variables. From Taguchi’s calculation optimum value for each responses has been predicted.
Keywords- Plasma arc cutting (PAC), Mild Steel EN19 Material, Taguchi method, Design of experiment (DOE) and ANOVA.
