What does the term Flushing mean in Electric Discharge Machining?

Flushing refers to the method in which the dielectric fluid flows between the tool and the work gap.The efficiency of machining depends to a greater extent on the efficiency of the flushing. The wear debris present in the spark gap should be removed as quickly as possible. With poor flushing there is a possibility of build-up of the machined particles in the gap resulting in the short-circuiting and lower material removal rates. Problems with improper flushing are: uneven and significant tool wear affecting accuracy and surface finish; reduced removal rates due to unstable machining conditions and arcing around regions with high concentration of debris. It is noted during an experimental study that there is an optimum dielectric flushing rate of about 13 ml/s while machining AISI O1 tool steel, where the crack density and average thickness of the recast layer are at a minimum.
