This paper presents an experimental investigation to develop the mathematical model for various wire electric discharge machining (WEDM) characteristics of aluminium silicon carbide 10% metal matrix composite Al/SiC10% MMC. The attempt has been made to optimize the range bound process parameters for maximizing material removal rate (MRR) with minimum surface finish (Ra). Classical experimentation technique was used to perform experiments for triangular, circular and straight shape cuts on Al/SiC10% MMC as majority of industrial products are manufactured by these shapes or combinations. The machining characteristics MRR and Ra were studied using multiple linear regression models for different shape cuts. The test results proved that MRR and Ra values were significantly influenced by pulse on time, servo speed and volumetric area of Al/SiC10% MMC for different shape cuts. Linear programming (LPP) was used to compute optimized process parameters for different shape cuts and satisfy industrial wide spread application requirement by quality machining of Al/SiC10% MMC
