In
electro discharge machining, the erosion of metal is achieved
By
inducing high voltage current in the workpiece
By
inducing low voltage current in the workpiece
By
the rapidly recurring spark discharges impinging against the surface of
workpiece
By
passing electrolyte solution between the workpiece and tool
By
the rapidly recurring spark discharges impinging against the surface of
workpiece
In
electro discharge machining (EDM) process, the control of erosion of the metal
is achieved by the rapidly recurring spark discharges produced between two
electrodes, one tool and the other work, and spark impinging against the
surface to the workpiece which must be an electrically conducting body.
Hence,
the correct option is (C).
