Thanks Jon,

Can someone point me to pictures of the CNC punch head types out there?
What are the fastest punch head types?

SIX FEET? I don't think you are going to find too many EDM machines in that
size. Waterjet machines are available in that size, but not real common.
CNC punches that can handle a 6' sheet will be fairly easy to find. A well-
maintained punch and tooling will make edges that need very little work, but
there will be a tiny folded-over edge on the back of the sheet.

Wire EDM is an expensive process, and likely will be way to expensive for
a one-off. Waterjet shops will be more accepting, I think, for a one-off
like this. But, the CNC punch can whip out stuff faster than either of
these
by a large margin. If the letter is really 9" x 6" in size, the CNC
punch can
do this letter in a matter of seconds. Waterjet would take a minute or so,
doing the pierce-through and then cutting the letter. EDM would take much
longer, although aluminum should go faster than some materials. it
might take
a half hour on a late-model machine. I don't know if EDM is commonly used
on aluminum, I'm more familiar with seeing it done on hard steels.

Laser is another technology, but it takes a BIG laser to cut aluminum, and
all laser cutting is expensive due to machine cost and consumables.
