Electron Discharge Machining. Heard about it in my machinist days, but
never did it. The use of an electric charge and a chemical solution to "eat
away" steel in the shape of a machined carbon electrode. I have forgotten
the electro-chemical process by which it works. Machinists sometimes call
it "burning" as in "you could burn that out". There are specialists who
will come to a machine shop or industrial plant as an emergency service with
their portable rigs to "burn out" broken taps or the like.
