What is the easiest way or tips and hints, to saw small cutout
designs in half inch plexiglass for hydraulic forming?
I've recently had the opportunity to work with a glass artist who
needed some prototypes milled that he's using to make molds for glass
casting. The pieces range between 3-4 inches in diameter.
Perhaps it's perhaps it's already being done, but while milling these
large pieces, it occurred to me that a milling machine could open up
a lot of design possibilities for making molds and dies to be used in
a hydraulic press.
When I shared a studio with another metalsmith about 10 years ago, I
had access to a hydraulic press but it's been a while since I've used
one, so my knowledge of the process is bit rusty. But, it would seem
to me that you could design some very interesting 3D forms using
CAD/CAM, including two-sided dies or just a one sided mold that you
could use with rubber to press-mold metal.
Plexiglas isn't the best material to mill but Delrin or Nylon would
easily hold up under the pressure of a hydraulic press.
Has anyone made dies for press-molding jewelry forms with a CNC
