Surface quality evaluation of 0.2 % C and AISI 304 steels in turning with sustainable lubricating condition

Metal working fluid (MWF) plays a significant role in metal machining operations to obtain the desired dimensional accuracy and better surface quality in the machined component. Legislations have set limits on the usage of mineral based MWFs because of their carcinogenic behavior and adverse effect on health and the environment. The saturated fatty acid of vegetable oil facilitates a better layer of lubricant between work tool interface compared with the mineral oil based MWFs. This paper describes the surface quality of 0.2 % C and AISI 304 steels while using formulated novel white coconut oil based MWF and mineral oil based MWF in flood cooling and dry machining. The machining parameters were selected according to the recommended specifications, and quality of the machined surface was measured. The novel white coconut oil based MWF has expressed better surface quality for almost all the set of machining parameters compared to other cooling configurations.
