Processing of Al/SiC/Gr Hybrid Composite on EDM by Different Electrode Materials Using RSM-COPRAS Approach

The present research used the stir-casting method to develop an Al-based composite. developed composite exhibited challenges while being processed on conventional machining. Thus, a non-traditional machining process was opted variables selected for current were pulse off time (Toff), (Ton), servo voltage (SV), (I), and tool electrode. Three electrodes (SS-304, copper, brass) (Al/SiC/Gr). experimental plan designed using response surface methodology (RSM). output responses recorded analysis material removal rate (MRR) wear (TWR). obtained data optimized complex proportional assessment (COPRAS) machine learning methods. settings predicted by RSM–COPRAS Ton: 60 µs; Toff: SV: 7 V; I: 12 A; tool: brass. maximum MRR TWR at suggested 1.11 g/s 0.0114 g/s, respectively. A morphological investigation of machined conducted with scanning electron microscopy. examination (machined) presented presence cracks, lumps, etc.
