Article Description

The present work proposes a decision support system in TOmada de Decisao Interativa Multicriterio (TODIM) to identify the best possible processing condition for machining AA6061/Al 2 O 3 /10p, a metal matrix composite using an electric discharge machining process. Various input parameters, i.e., discharge current, gap voltage, and discharge duration, have been considered independently while carrying out the experimentation. The following outputs were measured during the experimentation process: material removal rate, wear ratio, and average surface roughness. A total of twelve experiments were carried out. Following optimal process parameters have been revealed from the application of the TODIM methodology, I d (A) = 10 A, V g (V) = 35 V, and T on (μs) = 200 μs. Also, the machined surface was analyzed to check the performance of the process.
