Experimental Investigation on the Performance of Coconut oil Based Nano Fluid as Lubricants during Turning of AISI 304 Austenitic Stainless Steel

摘要

This research work presents the performance of nano cutting fluid in machining, one of the most fundamental process in manufacturing industries. The heat generated at the tool-chip interface during machining is critical for work piece quality. The cutting fluids which are widely used to carry away the heat generated at the tool-workpiece interface in machining process that do not possess a pathogenic clinical history and are relatively free from inherent hazards. Hence there arises a need to develop an eco-friendly and user friendly nano cutting fluid over conventional cutting fluids. Coconut oil has been used as one of the cutting fluids in this work because of its thermal and oxidative stability which is higher than that of other vegetable based cutting fluids used in machining industries. The present work investigates the application of nano Boric acid, solid lubricants suspension in coconut oil during turning of AISI 304 austenitic stainless steel with carbide tool. Where in nano boric acid solid lubricants of 50 nm particle size were suspended in coconut oil, base lubricant. So the variation of average tool flank wear, surface roughness of the machined surface and cutting tool temperature with cutting speed and feed are identify with nano solid lubricant suspensions in coconut oil.
