Abstract

This paper presents an experimental investigation of the material removal rate and spark gap and the effect of wire EDM process parameters during machining of newly developed Al/ZrO2(p) metal matrix composite (MMC) material. In the present work, 5% of ZrO2 particulate by weight have been added to prepare Al/ZrO2(p)-MMC by stir casting techniques. Central composite design (CCD) of response surface methodology (RSM) considering full factorial approach for six process parameters has been used to design the experiment. Experiments have been performed in order to investigate the effect and optimization of input process parameters on performance measures like material removal rate and spark gap. The multi-optimization results obtained by initial parameters setting, response surface methodology and grey relational techniques have been compared and validated by confirmation experiments. The experiment results of performance characteristics have proved that newly developed MMC can be machined effectively by wire EDM
