Statistical Optimization of Wire-EDM During Processing of Hybrid MMC

High tool wear rate and high cycle time in conventional machining have provided a dreadful response for harder materials and it is also very difficult to machine the complex shapes by such machines. Wire Electric Discharge Machining (WEDM) is widely used non-conventional machining for the hard materials and intricate shapes. In this paper, an attempt is made to investigate the surface integrity of the machine surface as well as the performance of the hybrid MMC A359/Al2O3/B4C during the wire-EDM process under different operating conditions. SEM analysis has been carried out to analyze the machined surface. The output response is measured in terms of surface roughness and MRR. The analysis part has been done by using the L27 Taguchi's array under the randomly designed experiment trials. At the end of the result, grey relation analysis has been made as a confirmation attempt to compare the performance effectiveness of the proposed method.
