Does anyone who has 3D capable CAD/CAM have the ambition to generate
some G-code for me? What I need is two sets of code for a half egg
shape, a positive and a negative to use in a press. The egg would be
approximately 3.5" diameter by a suitable length perhaps ~4.5" or
so. The pos/neg die clearance should be .020". Post processor for
Mach3.

I would help, but it sounds like you already have better qualified
helpers than me. Laminated hardwood stamp and die huh?
Interesting. I take it that it will be a modestly small production
run then?

I'm hoping oak will be sufficient (backed by 3/4" steel press plates)
to form relatively soft AL flashing at the 1.75" depth needed. If it
works well, I wouldn't expect to press more than a couple dozen
pieces or so.

Get some industrial thickness aluminum foil and press four or five layers
into the mold one layer at a time.
That's something your friend could do on his or her own, uding the core (
not drawm yet) as a pestle.

At about .015" the AL flashing material is relatively thin and soft yet
should be solid enough to be reasonably durable, hopefully it will
behave ok.

My other thought/comment/question.

I know they make aluminum cooking pans, but is there a particular
grade/alloy/type for food products like baking pans?

Not that I'm aware of. There would be at least two alloys used, one for
case goods and one for formed goods.
