During the cold rolling in a rolling mill synthetic lubricants consisting of mineral oils, biodegradable oil with chemical additives are being used for lubrication to obtain quality rolled surface. The quality of rolled product in cold rolling is largely influenced by surface roughness and chemical wear of rolled surface. Several factors contribute to quality of rolled product among those, composition of lubricant, amount of lubricant and operating speed of roller are more significant. In this study the identified factors were analysed using design of experiment approach. Robust design factor values were estimated by grey relation method. The result indicates that the selected process parameters significantly affect the quality of rolled product. The results are further conformed by conducting confirmation experiments.
