In
the electro-discharge machining process, the work-piece and the electrode are
submerged in
A dielectric fluid
An
abrasive slurry
An
electrolytic solution
Vacuum
A dielectric fluid
During
the electro discharge machining (EDM) process the work piece and the electrode
are submerged in the dielectric oil, which is an electrical insulator that
helps to control the arc discharge.
Hence,
the correct option is (A).
