Abstract :
Electro discharge machining (EDM) is a non-
conventional machining process, in this process does not
require any mechanical contact between the electrode
and the workpiece. Usually, the dielectric fluids are used
to create a connection to the electrode and the
workpiece. Generally, fluids (kerosene, EDM oil,
gasoline, deionized water, etc.) and gases (oxygen,
helium, etc.) are used as dielectric in the EDM process,
which serves as electrical insulators and semiconductor
between electrode and workpiece. Also, the fluids
remove the dust particles from the machining surfaces of
the workpiece. However, the liquid medium is widely
used in the EDM process. On the other hand, the gaseous
dielectric is also often used to fill in any specific need.
Nowadays, mixed dielectric fluids are very commonly
used for machining purposes, because of some lack of
efficiency with plane dielectric fluid. In this study, it is
shown the advantages of several dielectric mediums
(liquid and gas) in the EDM process for different
materials. Furthermore, it also reviewed how to improve
output parameters with respect to input parameters with
the help of various types of mixed dielectric fluids.
