Abstract
This paper studies the effects of soluble cutting fluid-based CuO Nanofluid on machining force and surface roughness in turning of hardened AISI 4340 tool steel. These influences, Moreover, are compared with the outputs of similar tests through dry and soluble cutting fluid. The obtained results showed 1% volume fraction of CuO Nanoparticles added to soluble oil as cutting fluid was considerably reduced machining force and surface roughness in comparison to soluble cutting oil and dry. The investigations indicated that CuO Nanofluid reduced surface roughness and machining force by 49% and 24% respectively. Moreover, the results illustrated that the lowest surface roughness obtained in cutting speed 250 m/min, feed rate 0.1 mm/rev and cutting nanofluid.

Abstract
Due to the difficulties and limitations in grinding hard materials, the use of nanoparticles in the Minimum Quantity Lubrication method can be effective as an appropriate solution to improve the efficiency of lubricating fluids. In this study, the effect of using a combination of carbon nanotubes and copper nano oxide on the surface quality of Inconel 718 alloy during grinding by Minimum Quantity Lubrication has been investigated.
The results showed that the use of nanoparticles in Rapeseed oil reduced the roughness and improved the surface health of the samples. The best surface topography with the least amount of pits and Furrows was obtained by combining nanoparticles with 3wt% in rapeseed oil, so that the surface roughness of the samples was reported 0.243 μm during this method, which is compared to the net use of CNT and CuO decreased by 14% and 7% respectively. Also, during the use of nanoparticles in minimum quantity lubrication, the amount of surface roughness compared to dry, flood and minimum quantity lubrication with rapeseed oil, decreased by about 35%, 13% and 18%, respectively.
