surfacing problem...

any help with this would be appreciated,

i have a plastic formed component, that needs at the moment a flat
sheetmetal (0.2mm thick) to be formed over this surface, this will
then be edited to allow for holes, slots etc.any ideas...?

 

any help with this would be appreciated,

It might help in getting a reply if you'll be more specific as to your
goals (part, developable sheetmetal part with flat pattern, create
associative link between the parts, etc.), what you do and don't
know about how to go about it, what version of Pro/E you are
using.

Did you try using a sheetmetal form? It involves an assembly operation (your
molded surfaces to the piece of sheetmetal) and generating a sheetmetal surface to
match part (inside of sheetmetal molded to outside of plastic part) by using the
part as a female form punch. If you are not using the sheetmetal module of Pro/e
for this, you should be.

I second Jeff's request for more info, including info on what you've tried
already. Also info on when you plan to do the slots and holes ~ before or after
the forming operation or even integrated as a progressive form/punch set of
operations. (If the holes/slots are at the edge of the formed metal, they might be
done first on the clamped edges, possibly on the last forming operation. But this
is die design stuff I'm sure you know better than I do.) If after forming, will it
be done in a way (e.g., laser or wire edm) that puts no stress on the formed part?

The Pro/e part of this, I think, is the easy part, once we know what you're trying
to do.

I haven't seen, and don't know the complexity of this part, but it is
possible to create a sheet-metal wall offset from a surface, without
studying this extensively I think this should satisfy your need. From what
I've read you may not want a space between the surface and the sheet-metal
wall so the offset would be zero, bust you can also provide a little built
in tolerance by specifying a minimal offset. As with any offset features in
Pro-E, the ability to offset it depends on the quality and complexity of the
surface, but 2mm is fairly small so you will probably have success.
