Experimental Investigations on Wire EDM of Al7075-TiB₂ In Situ Metal Matrix Composite

Abstract:

This paper focuses on optimization of process parameters for wire electric discharge machining (WEDM) of In-situ Al7075-TiB₂metal matrix composites processed by stir casting technique using Taguchi method of experimental design. The effect of pulse-on, pulse-off, current, and bed speed on dimensional accuracy, surface roughness and volumetric material removal rate (VMRR) have been investigated keeping voltage and flush rate constant. L₂₇ orthogonal array of Taguchi technique was used for experimental trials. The optimum process parameters have been identified. Significant process parameters were identified from the analysis of variance (ANOVA). Further, verification experiment has been carried out to confirm the performance of optimum process parameters.
