Investigation of Electro Discharge Machining Parameters Using Aluminium Powder Suspended in Dielectric

Powder suspended dielectric is one of the newest techniques for improving the efficiency of electro dischage machining. In this research, by adding Aluminium powder in less than 25(gama)m size in dielectric, a variaty of machining parameters, like Gap size, material removal rate, and surface roughness were investigated and compared in finishing and semi finishining regimes in two states of with powder and without powder. The results show that, due to adding powder to dielectric, a considerable improvement in quality machined workplece is achieved.
