摘要：

This paper reports experimental investigations of the effect of machining parameters (pulse-on time, pulse-off time, wire speed) on the performance measure like cutting speed (CS) or feed, kerf width(KW) and surface roughness(SR) during wire electrical discharge machining (WEDM) of newly prepared compo casted AA6061/cenosphere AMCs. Box Behnken of response surface methodology is employed to analyse the effects of significant machining parameters on the performance characteristics. ANOVA analysis was imposed to investigate the influence of process variables and their interactions. Further, a second order quadratic mathematical model has been developed in order to estimate the performance characteristics. The analysis reveals that pulse on time and percentage of reinforcement were found to be the most significant factors affecting all the three responses. (c) 2017 Elsevier Ltd. All rights reserved.
