چکیده
In this study, the eff ects of cutting parameters on kerf and surface roughness were experimentally investigated in WEDM. Al 7 475-T7 351 alloy was selected as the work material to conduct experiments. The factors selected for the optimization are the pulse on time, table feed rate and the wire speed, each of the factors in three diff erent levels. An optimal parameter combination of the WEDM process was obtained by applying the grey relational analysis (GRA). Also, the analysis of variance (ANOVA) was carried out for fi nding out the contribution and the eff ects of machining parameters on the multiple performance characteristics (MPC).
