Question

Metal removal in electric discharge machining takes place through

Correct answer (B) melting and vaporization Solution In Electric Discharge Machining (EDM), material removal occurs due to the high thermal energy generated by a series of discrete electrical sparks between the tool and the workpiece. This intense heat causes the localized material to melt and vaporize, which is then flushed away by the dielectric fluid. Turn this into a strength.
