How do you control inside radius on forming tool?

    I have made a few forming tools in the past, all of which had a
    critical outside radius. I found these quite easy to build, but now
    I'm stuck with controlling the inside radius.

    I have a shape based on a Mate forming tool (tool code "A0"). This is
    a card guide where the card rides along the two developed inside
    radius'. I want a forming tool that best mimics an anvil that controls
    the inside radius, then the punch and form side that pre-punches then
    bends the metal around the anvil.

    Since every forming tool I've built before simply plunges into the
    material and lets the software figure out the inside radius, I'm at a
    loss for how to control that same inside radius with the equivalent of
    an anvil.

    Short of some extra math, does anyone have an idea?

    You can find the datasheet of the tool design on page 2 of the
    following doc:

    Thanks!

    Ok, but a calculated radius, whether developed inside or outside, is
    based upon the sheet metal properties, yes? If the form tool is the
    equivalent of air bending, how do I plunge the tool from the front,
    and control the inside radius on the rear (since that is where the
    anvil goes)?

    Maybe for representation sake I could forgo the accuracy, but for
    collision tests, I don't know.

    Thanks for the freebie, that's exactly what I'm trying to achieve. I'm


    with multi bodies the little "bridge" (.00004") between the 2 halves isn't
    needed.
