Abstract

The present study deals with the optimization of parameters to check the effectiveness of thermoelectric machining of aluminum based SiC reinforced composites. Here, hybrid ED machining of Al-SiC metal matrix composites (MMCs) is investigated in magnetic field incorporated conventional Electrical Discharge Machining (EDM). The input processing parameters, such as pulse-on/off duration, current were assessed to analyze their outcome on the response parameters in terms of material erosion rate (MER), microhardness (MH), surface roughness (SR) and recast layer formation. The experimental results witnessed decrease in microhardness values and reduced thickness of recast layer, accompanied by a significant effect on MER and surface finish while machining in the magnetic field coupled higher spark energy. The experimental results conferred the process stability and an excellent correspondence with experimental verifications.
