Aluminium based alloys usages in aeronautical applications are machined by using WEDM to obtain complex profiles with good accuracy and minimum taperness. However, selection of cutting parameters for higher efficiency in WEDM is still not fully solved. In the present investigation, Sequence of experiments are developed to research the process parameters effect of Aluminium-6061 such as Pulse-on Time (TON), Wire Feed Rate(WFR), Pulse-off Time(TOFF) and Servo Voltage (SV) on MRR, Wire wear rate, Taperness (Geometric error) and Dimensional Deviation (dimensional error). Trial runs on Al-6061 are conducted by design of the experiments using taguchi methodology and a regression equation is developed for evaluating the relationship between input and output parameters. Genetic algorithm optimization technique is applied to yield global optimum results of process variables. Finally, comparison was done across experimental results and predicted the values of confidence level as 98%.
