Abstrakt: In the present work an effort is also made to evaluate the optimum combination of machining factors by applying the unique combination of response surface methodology (RSM), Shannon's entropy weight measurement with VIKOR method. Experiments were conducted on Monel 400 alloy based on Taguchi L16 OA (orthogonal array) to evaluate the impact of machining parameters like voltage (V), discharge current (Ip), pulse on time (Ton) and pulse off time (Toff) on the process to obtain the desired response characteristics namely material removal rate (MRR), tool wear rate (TWR) and Dimensional Deviation (DD). The Shannon's entropy weight measurement (SEWM) method have been proposed to assess the individual weightiness for all performance characteristic and by using VIKOR method the most optimal setting of machining parameters has been evaluated for improving productivity and minimizing the cost. The optimum setting of machining parameters found by the proposed method has of Ton 6µs, Ip 9amps, voltage 50V and Toff 3µs. The discharge current and pulse on time have the significant domination over the MRR, TWR and OC ensued by voltage and pulse off time. The application of VIKOR method for solving multi response optimization problem which would be helpful to the process engineers in selecting the most optimum parameter combination for making micro hole using Micro EDM has been systematically demonstrated.
