Parametric optimization of ball end magneto rheological finishing process on EN-31

Abstract

— This work is concerned to explore the effect of process parameters of the ball end magnetorheologial finishing on the magnetic work piece to achieve nanofinishing. Magnetizing Current, working gap and Nozzle speed have been considered as input parameters; however percent improvement in surface roughness considered as an outcome of the process. In Present work the experiments have been carried out with above mentioned input process parameters with the help of the standard L9 orthogonal array of Taguchi .The measurement of the surface roughness is taken with the help of contact type Contact Mechanical Profiler PGI 120. Experimental data has been analyzed by using pooled anova for finding the contribution of input parameters, and further searching best input values to obtain optimal/near optimal output value. In the end a generic input-output relation has been developed using regression analysis to predict output value for newer input values.
