چکیده مقاله
Electrical discharge machining EDM is the most widely and successfully applied process for machining of hard to machine conductive parts In this study the effect of input EDM process parameters on AISI H13, is modeled and optimized The process input parameters considered here include voltage V , peak current I , pulse on time Ton and duty factor η The process quality measures are surface roughness SR and material removal rate MRR The objective is to determine a combination of process parameters to minimize SR and maximize MRR The experimental data are gathered based on design of experiments D optimal approach Then, analyses of variance ANOVA and validation experiments have been carried out to select the best and most fitted regression models In the last section of this research, simulated annealing SA and particle swarm optimization PSO algorithms have been employed and compared for optimization of the performance characteristics A set of verification tests is also performed to verify the accuracy of optimization procedure in determining the optimal levels of machining parameters The results indicate that the proposed modeling technique and SA and PSO algorithms are quite efficient in modeling and optimization of EDM process parameters
