Study of surface quality in dry and wet external cylindrical grinding

Abstract

The grinding process is commonly used as finishing operation which makes the process distinguished from other machining processes. The process is practiced to obtain the best possible surface quality and dimensionally accurate of ground machine parts. The grinding parameters such as ground workpiece material, wheel type, wheel speed, workpiece speed, depth of cut and feed alter the surface finish of workpiece. The application of cutting fluid is generally carried out and the influence of selected cutting fluid on surface roughness is widely accepted positive. In this study, the examination of dry and cutting fluid application (wet) in grinding was studied and compared. It was observed that the dry grinding unexpectedly produced a better surface quality in the external cylindrical grinding of AISI 1040 steel. The selected grinding parameters such as depth of cut, feed and wheel speed showed more important factors on surface roughness. This study also examined material removal rates for dry and wet grinding processes.
