Optimal Selection of Cutting Fluid Using AHP and VIKOR

Abstract

Cutting fluids are important elements of manufacturing industries and are used in large quantities. But its use poses a serious health issue to the surrounding people working in its atmosphere. Hence, the disposal should be only after neutralization thereby protecting worker and aquatic life. This leads to select an optimal alternative that is not only environmentally friendly but also safe for human beings and aquatic life. Further, it should also perform at par with the mineral oil-based cutting fluid. In the present research, a framework has been proposed to assist the decision-makers in the selection and evaluation of lubricant by the Analytical hierarchical process (AHP) and VIKOR method. In the proposed research three cutting fluids i.e. Neem oil with 5% emulsifier, Neem oil with 10% emulsifier, and a conventional mineral oil-based cutting fluid have been considered as alternatives. These have been evaluated on the basis of different significant parameters like the temperature at the tooltip, surface roughness, and tool wear. The basic aim of this paper is to present the logical selection process of a cutting fluid as well as to show that ranking or choice of cutting fluid may also change if the priority of the parameter is changed.
