Cutting-fluid selection using complex proportional assessment method

The selection of right cutting fluid in the industrial environment is an important and complex issue due to their negative effects on health, safety, and environment, legislation and public environmental concerns. Although a number of mathematical approaches are available in literature to evaluate, select and rank the cutting fluids for the given machining conditions, but there is still need for a simple and systematic methodology to guide the user in selection of right cutting fluid for the given machining application. This paper presents a logical methodology to select a right cutting fluid using a novel multiple attribute decision making (MADM) method, i.e., complex proportional assessment (COPRAS) method. Two illustrative examples are presented from the literature to illustrate the capability and potential of COPRAS method in selection of cutting fluid and the results obtained by the COPRAS method are compared with the results obtained by the past researchers.
