| Description | Journal: Iop Conference Series: Materials Science and Engineering A prodigious research work is being effectuated to endorse the optimal machining parameters while entailing present day machining techniques to bring outclassy products. This research work insisted on suggesting the optimum process parameters of die sinking EDM with 8mm diameter copper electrode during machining AISI D2 steel using TOPSIS.Taguchi’s L9 Orthogonal Array method was adopted to design 9 experiments in total and Pulse on time $(T_{on}$), Servo voltage (SV) and Peak current $(I_{P}$) are chosen as input parameters. Three levels of each parameter were selected for designing the experimentation. EDM oil which is a synthetic oil is selected as dielectric and all the values of Material Removal Rate (MRR), Tool Wear Rate (TWR) and Surface Roughness (SR) for each experiment were noted as the output responses. Analysis of Variance (ANOVA) was done to recommend the impact of each input parameter on output responses. Analytical Hierarchy Process (AHP) was used to select the weightage of each response and then Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) which is a multi-criteria decision analysis method, was accompanied for determination of ideal parameters for machining AISI D2 steel. Eventually it is descried that the amalgamation of level 3 of pulse on time, level 3 of Peak Current and level 3 of servo voltage propounds the optimum result. |
