Abstract

The comparative performance of soluble oil, Neem oil and water melon oils were investigated for application as Cutting fluids in a turning operation using Mild steel and spindle speeds of 250 rpm, 710 rpm and 180 rpm; depth of cut of 1 mm, 0.5 mm and 0.75 mm were used respectively, automatic feed rate and an ambient temperature of 34°C. Some physicochemical properties relating to cutting fluids were also investigated. Results shows that the Specific gravity of Neem seed oil was 0.9304 and Water Melon seed oil was 0.9324. The flash point for Neem seed oil was obtained as 157°C, Water melon seed oil 117°C. Viscosities were obtained as follows; Neem seed oil 8.08 cSt, Water melon seed oil 8.56 cSt. Pour point for Neem seed oil was +8, Water melon seed oil -8. % Wt of Sulphur was found to be 0.0293 for Neem seed oil, Water melon had -0.0081. pH for Neem seed was 3.6 and Water melon seed oil 5.5. Machining results shows that at 100 % oils, Water melon seed oil produced (54.66°C) and Conventional cutting oil (53°C) are not good as lubricant for metal cutting operations as the temperatures obtained using these oils exceeded the temperature obtained during dry machining at 50°C. The least temperature of 37.33°C was obtained while machining with 25 % Neem seed oil and 75 % water emulsion. All the oils – water emulsion ratios were effective as coolants and comparable to the Conventional cutting oil tested. How ever, the best surface finish was obtained from the dry machined sample. Amongst the oils tested, 100 % water Melon seed oil produce the best surface finish.
