Environmental and Ecological issues call for the reduction in usage of cutting fluids in metal cutting industry. New techniques are being inquired to achieve this objective. Hard turning with minimum quantity lubrication is one such technique which can alleviate the pollution problems associated with cutting fluids. In the present work, vegetable oil based cutting fluids like castor oil, palm oil and ground nut oil is made to drop at tool-work interface using over-head system. The present paper deals with experimental investigation carried out for machinability study of AISI D3 steel in combination with CVD coated cemented carbide inserts of different styles and to obtain optimum process parameters using TOPSIS and Desirability function analysis. An orthogonal array, closeness coefficient, composite desirability and analysis of variance (ANOVA) are applied to study the performance of process parameters such as insert style, cutting fluid cutting speed, feed and depth of cut with consideration of quality characteristics i.e., Surface roughness, material removal rate and specific energy. Finally a clear comparison is presented between DFA and TOPSIS
