Influence of Process Parameters in EDM Process- A Review

Abstract

Abstract-Electrical discharge machining is a nontraditional machining process which removes metal by a series of discrete electrical discharges that cause high temperatures which is enough to melt or vaporize the metal. The process is adopted for the materials which often have special properties that make them difficult to machine by conventional machining. In present study work of different researchers has been discussed which shows the effect of process parameters such as pulse on time, pulse off time, gap voltage , peak current and duty factor on output responses such as tool wear rate (TWR), material removal rate (MRR) and surface roughness (Ra)
