A Comprehensive Review on Impact of Machining Parameters on MRR and SR

The electrical discharge machining (EDM) process is a non-conventional machining process that is utilized to create high caliber and exact dimension items. This machining (EDM) is used to machine the smallest to complex geometrical shapes.  Thermal energy helps to evaporate and melt the material from a work piece.  Circulation of  dielectric  fluid removes  out  the  debris  from working zone and maintains  the  stability of  machining process.  EDM process is generally used for machining with different applications such as automobile, aircraft, aerospace, tools and dies, etc. This paper provides a review on the effect of different input parameters of EDM such as current, pulse off time, pulse on time, etc. on material removal rate (MRR) and surface roughness (SR)
