Online published on 27 September, 2019. Abstract The work presents optimization of process parameters in wire electrical discharge machining process. This paper presents the results of experimental work carried out in Wire Electrical Discharge Machining of Super Ni 718 super alloy. Experiments have been conducted using 8 process parameters such as Pulse on time, Spark gap, Wire feed, Wire tension, flushing pressure, servo speed and peak current at 3 levels for obtaining responses like surface finish, material removal rate and dimensional deviation. The optimal setting of parameters is determined through experiments planned, conducted and analyzed using Neutrosophic sets and TOPSIS method. Top Keywords WEDM, Super Ni 718, Neutrosophic sets, TOPSIS. Top | |
