Abstract
In the past years many researchers have done various advancements in material removal rate, wear of electrode is improved and various researches had done on physical and electrical parameters of EDM machine. This new research contributes the similar objectives to enhance the material removal rate and to increase the life of electrode by reducing the wear rate of electrode. So this paper review the past research work done on porous electrodes to improve the life of electrode and to reduce the lift up time of electrode to flush debris and various work on porous electrodes to reduce lift up time.
