That could be watercut cnc job -
That could be lasercut cnc job -
That could be Plasmacut cnc Job -
The plasma would slice through - and if kept moving wouldn't distort
the plate. That small hole in a big plate won't give much possibility
for a warp.
Circle cutting is typical (drill press), but you need a deep throat.
Plasma torch can be guided between or around (inside is best) a wood circle.
Lots of ways.

I need to make a two inch hole near the center of a four foot square
3/16" steel plate. It doesn't need to be perfect, could be slightly
irregular. Would a cutting torch be OK, or would the heat permanently
distort the plate?
What other methods would work? A plasma cutter sounds good to me, but
I don't have one. I guess I could take it somewhere and pay to have
it done.
Best option: Very large radial arm drill press... Find someone with one.
Has to have a 24" or greater throat.
Second best: Magnetic mount drill with an annular cutter - See
www.hougen.com or a similar manufacturer.
Third best: Really good geared down, two hand hand drill with a hole saw,
annular cutter, etc. Lots of prayer...
They might just make hole cutters for electrical panels that work too...
The kind you drill a small hole for then put a device that "shears" it's way
through as you tighten it like a bolt...
