This machine:

is claimed to be good for up to 20 gauge mild steel.

It seems that 5052-H32 aluminum is the stuff to use, if you're going to
use aluminum.

What thickness of this stuff should I expect a "20 ga mild steel"
shear/brake/etc combo to handle?

One rule of thumb is a 3-gage difference between steel and ally.

So .045? Argh. I need to shove at least 1/16 thick material in there.
It doesn't have to be high-tempered 6061, but I need that thickness to
accommodate a bearing (http://www.igus.com/igubal/igall2.asp?p=Clip if
the link works) and to make the assembly stiff enough.

Sigh.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.
