RESPONSE SURFACE ANALYSIS OF CYLINDRICAL GRINDING FOR MATERIAL REMOVAL RATE OF ALLOY STEEL EN9

Abstract

Grinding is a term that describes machining with high-speed abrasive wheels, pads, and belts in contemporary production. Grinding wheels are available in many forms, sizes and types of abrasives. The next chapters will go over some of the most common types of wheels and abrasives. For single optimization the analysis of variance (ANOVA) results based on the estimated MRR values are provided, which show that depth of cut has the highest contribution of 92.06% and then the minimum influence due to cutting speed by 4.65% and feed rate by 0.94% in determining the MRR values, thus validating the above-obtained conclusion. The optimum combination for input control parameters is A2B3C1 and calculated grey relational grade by equation (7) is 0.4413. Table 5.9 shows the confirmation experiment for response parameters. It can be noted that the experimental value of Cutting Speed (VC) in rpm, Depth of cut mm and Feed Rate mm/rev. are considerably enhanced by response surface methodology.
