Experimental determination of the effect of some straight biological oils on cutting force during cylindrical turning

Abstract

Cutting fluids of various types are usually employed to control the heat generated in machining. The continued application of conventional petroleum based metal working fluids is being challenged by the need to reduce overall volume of fluids, minimize health risks and bio-contamination. Bio-oils assisted machining is an environmental bio-compatible technology for desirable control of temperature. This paper investigates the effect of some vegetable based oils on cutting force during cylindrical machining of mild steel, aluminium and copper.The results indicated that bio oils are suitable for metal working fluids but the effects of the bio-oils on cutting force are material dependent. Groundnut oil exhibited the highest reduction in cutting force when aluminium was being turned at a speed of 8.25m/min and feeds of 0.10, 0.15 and 0.20mm/rev, respectively. Palm kernel oil had the best result when copper was turned at feeds lower than 0.15 mm/rev. However, at higher feeds, groundnut oil had the best result for copper. Coconut oil recorded the highest cutting force in all the three materials machined followed by shear butter and as such are very mild in reducing cutting force during cylindrical machining.It is concluded that groundnut and palm kernel oils are effective in reducing cutting force during cylindrical turning. Though, the lubricating and cooling action is material dependent, groundnut oil is the best among the four bio-oils investigated.

“…3 Biological oil cutting fluid has several superior features compared to the petroleum-based cutting fluids, such as, reduced overall volume of fluids due to higher viscosity, minimized health risk to workers and minimized biocontamination. 4 Vegetable oils are particularly effective as boundary lubricants as the high polarity of the entire base oil allows strong interactions with the lubricated surfaces. However, the main weakness is their relatively poor oxidation stability.…”

“…However, Soy-based metalworking �uid had slightly higher tapping torque efficiency in the semisynthetic form compared to others. As cutting �uids, ground nut and Shea butter oils generated lower cutting forces and coefficient friction while turning mild steel, aluminum, and copper workpieces [11]. �etter surface �nish is also reported under these oils.…”

“…Sen et al [48] showed the benefits of applying MQL with vegetable oil, and the advanced modeling technique to establish a beneficial manufacturing system. Ojolo et al [49] performed an experimental work to find out the influences of vegetable oil viz. groundnut oil, palm oil, kernel oil, shear butter oil and coconut oil on cutting forces during machining of mild steel, copper, and aluminium.…”
