Same topic: I never DID any EDM work, so really don't have much of a "feel"
for this detail of which you speak, but the "bubbling and explosions" at the
"cut", seems to me, would be considerably altered by a considerable
"atmospheric" pressure-change where the EDM-vessel was being used. It seems
that said "boiling" would be considerably-reduced (tinier bubbles, or none!)
if the process were done under TWO or more atmospheres of ambient pressure!
Note the "black smoker vents" at the bottom of the ocean in those PBS
educational shows: There is NO "steam", yet the temperature of the water
directly IN those jets is 1400°, as that is many hundreds of feet below the
surface of the sea! So, EDM done under high pressure migh, say, result in a
VERY smooth (polished?) "cut-surface"? Some one "in here" into experimenting
oughta TRY this! I see a potential market for "containment vessels" for
EDM'ers, etc... Hmmm...
