Development of Cutting Fluid from False Walnut Oil Using Design of Experiment,

Abstract

: In this study, false walnut oil based cutting fluid was formulated for machining alloy of steel materials. The physiochemical properties of the oil as it affects the formulation of cutting fluid were investigated. Emulsifier, biocide, corrosion inhibitor and oxidant were used as additives in the formulation process using design of experiment method. Design expert software version 7.0 was used to carry out the analysis of variance and optimised the pH value of the cutting fluid formulated. The optimized pH value of the formulated cutting fluid was 8.029 with a viscosity of 2.31 mm2/s. The optimum value was obtained using 9.35% of emulsifier (A), 0.97% of biocide (B), 10.61% OF anti-corrosion (C), and 0.64% of anti-oxidant (D).
