Abstract
This research work focuses on to find out the best possible combination of optimum process parameters in plasma arc cutting system during the machining of 12mm mild steel plate. Plasma arc cutting machine uses different process parameters like cutting speed, arc current, torch standoff distance to perform any cutting operation and response variables like material removal rate (MRR) and a kerf width gets changes corresponding to the input parameters. To optimize of all these process parameters multi responses analysis is done through experimental data obtained by using Taguchi's L9 orthogonal array as design of experiments and all data is analysed by Analysis of mean (ANOM) and Signal to Noise graphical approach using Minitab18 software to observe which input parameter has more effect on response variables.
Keywords- Plasma cutting, mild steel, Taguchi's L9, S/N Ratio, Analysis of Mean.
