Abstract

The present study deals with preparation of metal matrix composites(MMC), Aluminium (Al 6061) used as base material is reinforced with 3wt. % silicon carbide and 3wt. % Aluminium oxide (3wt. %SiC+3wt. %Al2O3) by stir casting method. The objective of this project is to investigate the effect of process parameters such as current (I), pulse on time (Pon) and pulse off time (Poff) on material removal rate (MRR) and tool wear rate (TWR) during electrical discharge machining (EDM) process. The tool used here is copper-tungsten. In this paper mathematical models are prepared by response surface methodology (RSM) and central composite design (CCD) for different combinations of process parameters. Analysis of variance (ANOVA) is used to check the significance of the model.
