“…From Table 5, it could be observed that the viscosity of the formulated rubber seed oil based cutting fluid is 4.25 mm 2 /s and is in agreement with the viscosity 4.39 mm 2 /s of castor oil emulsion cutting fluid [26]. The rubber seed oil based cutting fluid with pH value of 8.3 compares favourably with the pH value 8.2 of melon seed oil cutting fluid [23]. The stability test of the cutting fluids as described in section 2.2.3, showed that there was no phase separation of oil and water which indicates that the cutting fluid is stable.…”

“…This indicates that the lubricating property of the oil is high. The acid value of rubber seed oil (7.29 mg KOH/g) is comparable to that of melon oil (9.39) [23]. The saponification value of rubber seed (163.60 mg KOH/g) is comparable to that of neem (166 mgKOH/g) [22].…”

Due to the negative effects associated with the wide use of mineral oil, the desire for eco-friendly cutting fluids as alternative to mineral oil has become a global issue. In this study, rubber seed oil was used to formulate oil-in-water emulsion cutting fluid. Full factorial design was used for the formulation of the oil-in-water emulsion cutting fluid. The optimal process parameters obtained were used for the formulation of the novel cutting fluid and the cutting fluid was characterised. The characteristics of the formulated cutting fluid shows viscosity of 4.25 mm2/s, pH value of 8.3, high stability and corrosion resistant. Box-Behnken design was used for the turning operation and the performance of the rubber seed oil cutting fluid was compared with mineral oil. The input parameters were cutting speed, feed rate and depth of cut, while the responses were surface roughness and cutting temperature. Coated carbide insert was used as cutting tool. The ANOVA results show that the feed rate had the most significant effect on the surface roughness and cutting temperature followed by the cutting speed and depth of cut during the turning process. It was observed that the rubber seed oil based cutting fluid reduced surface roughness and cutting temperature by 9.79% and 1.66% respectively and therefore, it can be concluded that the rubber seed oil based cutting fluid performed better than the mineral oil in turning of mild steel.

Aluminium 8112 alloy has become a leading material in the aluminium family and currently used in the aerospace and automobile industries due to its excellent chemical and mechanical properties. However, during machining of aluminium alloy, one of the challenges faced by the manufacturing industry is the material adhesion, which increases the rate of chips discontinuity at the machining region and leads to a high surface roughness of the workpiece. The focus of this research is to proffer solutions to this material adhesion by implementing vegetable oil that is copra oil-lubricant, titanium dioxide (TiO 2 ) and multi-walled carbon nanotube (MWCNTs) nano-lubricants during endmilling of AA8112 alloy. Also, using quadratic rotatable central composite design (QRCCD) to study the effects of the machining parameters under minimum quantity lubrication condition, this research used the two-step method to synthesise the nano-lubricants and carried out the homogenisation using the magnetic stirrer and ultrasonic cleaner machine. The study considered five machining factors, including spindle speed, feed rate, length of cut, depth of cut and helix angle. The result from the surface roughness shows that the TiO 2 nano-lubricant reduces the surface roughness with 10% and 17% when compared with the MWCNTs nano-lubricant and copra oil. The minimum surface roughness of 1.15 μm, 1.16 μm and 1.35 μm, for the three machining environments, was achieved, respectively. Spindle speed is the most influential machining parameter, followed by the feed rate. The result of this study will aid the manufacturing industry to produce an excellent quality product for a cleaner manufacturing system.
