Formulation of Sustainable Eco-Friendly Cutting Fluid for Machining Process Using Statistical Method

Abstract

Sustainable eco-friendly cutting fluid is on high demand in present day machine tool industry because of environmental related issues. This study therefore, highlights the empirical model developed for pH value parameter when additives such as emulsifier, anti-corrosive agent, anti oxidant and biocide were used in the formulation of vegetable oil based cutting fluid with full factorial design. Second order model was developed for the pH value in relation to the formulation parameters. Analysis of variance was used to show parameters as well as their effects on the pH value model. when the system was optimized, it yielded most desirable optimal values for the formulation process variables as follows, emulsifier = 11.81%, anticorrosive agent = 3.67%, antioxidant = 0.76% and biocide = 0.64%
