Influence of Process Variables in Wire Cut Electric Discharge Machining on Surface Roughness of Al2285-MgO Composites

This paperpresents the influence of process variables in wire cut electrical discharge machining process of Aluminum 2285-MgO composite material. Electro-discharge machining process can be controlled by variables likepulse on time (TON), pulse off time (TOFF), servo voltage, wire speed, discharge current and servo feed have been investigated to reveal their impact on machining of aluminum 2285-MgO composite. Surface Roughness is an important parameter to characterize the machining efficiency. The pulse on time, pulse off time, and servo voltage were varied to study the effect of variation in surface roughness of composite material. The optimal set of process parameters has been predicted to obtain thegood surface roughness.
