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.

The 30" Central Machinery 3-in-1 I have will shear 1/16" 6061 but not
easily, and I sometimes have to readjust the blade gap after cutting
it. It is much happier with 0.050" 5052, which also bends better
without cracking.

I kinda need 1/16" 5052, for rigidity and to hold the panel-mount
bearing that I'm planning on using
(http://www.igus.com/igubal/igall2.asp?p=Clip, except that their web
site is having problems at this moment).

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