Reconnoitering the influence of Nano fluid of Nano boracic acid particles enriched waste coconut oil in Machining SAE 1045 shaft on modification Surface finish

Abstract

The surface quality is a prime factor in the failures of shaft by fatigue load. Here used coconut oil or waste coconut oil from Kerala chips shop are used for lubricating purpose for machining the precision shaft. This piece of research work investigating the effect of Nano fluid of Nano boric acid nanoparticles concentrated ‘used waste coconut oil’ for machining steel in the semiautomated lathe. The motor shafts are machined in dry condition called green machining then used polishing to reduces the surface roughness. This research tried to reduces the cost of manufacturing by using a low cost Nanofluid as coolant and lubricant in the cutting zone. Used coconuts oils are disposed as waste in many sweet and snacks shops. From such waste machine coolant is developed. The same was tested at conventional machining requirements and compared. Taguchi L16 orthogonal array employed as this investigation considered its 3 process variables at 4 levels. The process parameters analyzed and optimized by Taguchi analysis. The results recommended the proposed method as it outperformed.
