Effect of Cutting Parameters on Dry Turning of Austenitic Stainless Steel (316L)

Austenitic Stainless steel is one of the widely used stainless steel, SS 316 and SS316L are two different grades of which SS 316L has more corrosion resistant property and is weldable. Austenitic stainless steel (316L) is difficult to machine because it gets work hardened easily, its low thermal conductivity, high ductility, high strength also makes it machinability difficult. In this study theoretical analysis is done to find which cutting parameter has more effect on machining, it is done by using Taguchi and Fuzzy Inference System (FIS) from MATLAB. Data for theoretical analysis was collected from a combination of experiments which has a central composite design. The second order models were established for chip reduction coefficient and MRR. Subsequently second order models are used for converting those data to the data which is compatible for Taguchi analysis. The effect of various machining parameters on machining responses can be studied from the established model. The output from the simulation was generated as Multi Performance Characteristic Index (MPCI). Finding the position of various machining parameters was the next step of analysis. The rank with respect to various machining parameters cutting speed, feed, and depth of cut was established
