Experimentally investigating cutting force reduction performance by nano-alumina particles enriched waste coconut oil Nano fluid in electric motor shaft manufacturing

Generally, coconut oil is used for healing cut and wounds, cooking, lubricating machine parts etc. Used coconut oils are considered as waste and disposed on open channel and that is against to eco-friendliest. This piece of research work aims to investigate the effect of Nano- alumina based Nanofluid in machining of steel work in the lathe machine. The novelty in this investigation is the used coconut oil is reused as base fluid for preparing the nanofluid. Cutting force response is used for optimizing the parameters of the metal removal process. For investigating the effects, the cutting speed varied as 40 to 190 m/min, feed rate of the tool varied as 0.05 to 0.20 mm/rev and the CVD coated tool with 4 different nose radiuses used such as 0.3 mm, 0.6 mm 0.9 mm, and 1.2 mm, L16 orthogonal array involved to form the minimum experimental combinations. The results compared with existing practice of dry machining. The new fluid based cutting out performed and its process parameters influences were studied, optimized and mathematical model developed for prediction.
