APPLICATION OF TAGUCHI AND RESPONSE SURFACE METHODOLOGIES FOR SURFACE ROUGHNESS IN FACE MILLING OPERATION

The present research paper discusses about the use of Taguchi method and response surface methodology for optimization of surface roughness in machining of Gun metal with a HSS tool. The experiment was designed using Taguchi?s experimental design technique. The cutting parameters used are spindle speed, feed and depth of cut. The effect of cutting parameters on surface roughness is investigated and the optimum cutting conditions for minimizing the surface roughness is determined. Response surface methodology is utilized to establish a second order model between the cutting parameters and surface roughness. Spindle speed is found to be the most significant factor followed by depth of cut. The predicted values were found to be in close agreement with the experimental values, indicating that the developed model can be effectively used to predict the surface roughness in face milling of gun metal. The predicted values were confirmed by using validation experiment
