Abstract:

In the present work, laboratory develop setup was used for carrying out magnetic abrasive finishing. The present setup comprises of various components such as electromagnetic coil, voltage regulator, lathe machine, three jaw chuck. Minitab software is used for design of experiment and for statically analyzing the data. Three parameters such as magnetic flux density, Stand-off distance and voltage etc. with three levels were taken for finishing the mild steel work piece. For proper interaction of the various parameters design of experimentation has been carried out using Taguchi approach. Based on the Design of experiment, experimentation on the basis of various runs as depicted by Taguchi approach has been carried out and surface roughness values with respect to various runs were analyzed using the surface roughness tester (SJ201). For further identification of significant parameters and to determine the optimum parameters on which maximum machining has been carried out, Taguchi analysis was carried out by using larger the better approach. It has been found that Voltage is most significant factor followed by magnetic flux density and Standoff distance. Furthermore, modelling of the process has been carried out by using Regression approach. The equations predicted by the regression approach were further used for predicting the values of surface roughness. Furthermore for validating the statistical result experimentation was conducted and it was found that statistical results are in good agreement with the experimental results.
