Aim of present work is to investigate the effects of process parameters of plasma arc cutting of Inconel-625 material using analysis of variance. Three process parameters cutting speed, Arc Voltage and gas pressure are considered and experiments are conducted based on Taguchi L9 Array design. Process responses viz. mean surface roughness (Ra: center line average roughness) and material removal rate (MRR) and Kerf angle of machined surface are measured for each experimental runs. Higher material removal rate means industry can cut more metal in same period of time which ultimately results in more profit. And less surface roughness and Kerf angle makes finished product more suitable for assembly and easy handling. For minimum mean surface roughness and Kerf angle and maximum material removal rate, process parameters are optimized with the help of Taguchi design coupled with S/N ratios method. Analysis of Variance (ANOVA) is performed to get the contribution of process parameters on responses and Mathematical modelling is done by regression analysis.It was found that cutting speed has most significance.
