Cutting Fluid Selection for Environmentally Conscious Design for Manufacturing: An Integrated Theory

Cutting fluid is the key source of environmental pollution in each manufacturing process, with most favorable selection of cutting fluid for the environmental conscious design for manufacturing (ECDM) being an essential for reducing the environmental pollution. The objective factors considered for the traditional selection are of two: cost(C) and quality (Q) but ecological factors also to be considered from the ECDM point of view. The aim of this research is to select the finest cutting fluid which reduces the environmental impact (E), cost(C) and improves the quality (Q). A integrated method consist of analytical hierarchical process with preference selection index methods is proposed. An experimental case study on gear bobbing process is presented to justify the proposed model. The results show that proposed integrated model outperforms the other existing methods and provides optimal cutting fluid for gear bobbing process in green manufacturing.
