| Abstract | The Taguchi approach has substantially influenced the material subtraction industry in the past few decades. However, limited studies have applied the Taguchi, Taguchi-Pareto and Taguchi-ABC methods in electrical discharge machining (EDM) systems and no study has integrated the analytic hierarchy process to these methods in the context of EDM systems to process AZ91 magnesium alloy. The AZ91 magnesium alloy was chosen in this article due to its low weight, attractive corrosion resistance, low density, high strength, die-castability and potential for a wide range of industrial applications. The present authors attempted the above integrations and introduced the AHP method at the response table developmental phase of the Taguchi, Taguchi-Pareto and Taguchi-ABC methods. A key optimal parametric setting, AHP-Taguchi-Pareto is A3B3C3D1E3F3 which is interpreted as 126 units for a pulse on time, 60 units for pulse off time, and 230 units for pulse current, 20 units for gap voltage, 8 units for wire feed and 12 units for wire tension. Furthermore, the order of ranking of parameters according to the Taguchi and AHP-Taguchi methods coincides with 4/6 parameters, equivalent to 66.7%. A key ranking order of parameters according to the Taguchi and AHP-Taguchi-ABC Parts A, B and C coincide with 4/6 parameters, equivalent to 66.7% for the Taguchi-AHP-Taguchi-ABC Part A analysis. Based on the findings, it is concluded that by applying the AHP method to the Taguchi methods, it was possible to develop the optimised process values for the wire electrical discharge machining of AZ91 magnesium alloy material. |
