APPLICATION OF CRITERIA DECISION IN SELECTION OF CUTTING FLUID BASED ON DIFFERENT OPERATING CONDITION

Manufacturing Engineering

With the recent advancement in computer aided engineering tools, the designers have experienced extensive changes in design methodologies, especially in the field of computational design and optimization. In this work a comprehensive study of choosing cutting fluid on the basis of feed force, cutting force, surface roughness, radial force and its application has been carried out using TOPSIS and VIKOR method. For parametric design MS-excel is extensively used by the designers which give efficient results. Once the design sheet is made, there is no requirement to perform any calculations manually, by varying the value of variables i.e. feed force, cutting force, surface roughness, radial force and weight criteria for factors influence cutting in the MS-excel sheet and it will be easier to find the appropriate cutting fluid for turning process. For machining cylindrical work piece of mild steel the single point cutting tool is used. . The results are shown in the form of graphs. These graphs indicate the relative closeness value for different cutting fluids by VIKOR and TOPSIS. By observing the graph, the best cutting fluid for several cutting speeds and feeds is found out. This work represent the effects of a well-known parameter coolant flow on surface finish along with other elements such as spindle speed, feed, depth of cut, cutting force. As cutting fluid effects many parameters, therefore there is a need of developing an optimization method for selecting appropriate cutting fluid during turning process. This work is developed an optimization model to help the designer/manufacturer during selection of appropriate cutting fluid for turning process.
