Calculating the "spring back" on a stamped Part?

[xycnc]

Hello, This really isn't a mastercam question, but I know there are some very smart people on here who have the knowledge. Boss asked me today if mastercam can calculate the "flex", "twist"  or spring in a stamped part. Or if you could manipulate the geometry once it was stamped out and scanned to see how much more needed to be removed from the die.  I told him mastercam is a cam software with cad capabilities. That Solidworks or Inventor would have a better chance at doing that. But thought I would put it out here and see if anyone knows of or how it is done. We are trying to stamp out a impeller blade and eliminate as much of the R&D  out of it.  I thought I read something about a topic like this one on here before, but i couldn't find it. I would think something should at least be able to get us close. Thanks for your time and help.

Mastercam is considered a CAM package with some CAD facility.

You require full CAD/CAM with full engineering package. Solidworks, Catia, Siemens UX etc....

So Solidworks can do this? Is it an add on?

There is a plug-in for SW's...

Our designers use Logopress (plugin/addon, whatever it's called) with SW when designing dies. I'm not sure if figuring overbend is part of what it does, but we use it for designing prog dies.

Most , if not all, of the full engineering systems have modules for  various engineering categories  (see Thad's example above). These tend to be very expensive so they try and break them up to keep the price somewhat under control.

I've done this exact thing by generating slices along the centerline spline of the airfoil shape and then transforming the slice geometry to a flat plane representing the airfoil chord line of 2D profiles with relative LE offset to the centerline. The easy thing to start with is the defined section views of the airfoil off of the blueprint, which give you all your critical slice points. Die adjustments for twist and springback can then be dialed in at the sliced sections as planar angle adjustments, and the die surface re-swept through the adjusted wireframe. 

There are software packages that can probably do it faster, but I never used any specialized add-ins for this type of work, as the application differs from typical sheet metal spring calculations and there wasn't much out there claiming to be able to do this at the time.
