Abstract

Engine valve manufacturing involves significant amount of machining during its manufacturing activity. Suitable cooling agents or cutting fluid are used to remove heat produced during cutting operation to maintain machining finish and insert life. Cutting fluids are one of major waste involving cost for disposal and hazard to environment, reduction in their use can play key role to meet stringent environment norms and achieve economic machining. Dry machining is an alternative solution involving compressed air replacing cutting fluids. The most important measures of surface quality during the machining process is the average surface roughness (Ra) which is mostly caused by many machining parameters such as true rake angle, side cutting edge angle, cutting speed, feed rate, depth of cut and nose radius. This paper a model of surface roughness was developed based on the response surface method to investigate the machining parameters such as feed rate, cutting speed, nose radius, and machining time, affecting the roughness of surface produced in dry turning process. The experiment has been designed and carried out on the basis of a three-level factorial design which provide the perfect combination of cutting parameter to obtain optimum result of turning process.
