Electrical Discharge Machining of LM24 Al Alloy-SiC Reinforced MMC

Metal matrix composites are one of the newly developed engineered materials of considerable interest. Metal matrix composite consists of at least two constituent parts of which one constituent part being a metal and the other part may be a different metal or another material such as ceramic or organic compound. These materials are known as the difficult-to-machine materials because of the hardness and abrasive nature of reinforcement element like silicon carbide (SiC). Hence they impose machinability related challenge to conventional machining process such as turning milling etc. Electrical discharge machining (EDM) is a non-conventional process becoming a popular choice for machining these materials.
