Quarter Manufacturing Force Estimate

  1. Apr 1, 2013 #1
    Hi,

    What would be the approach to getting a good estimate of the amount of force needed to stamp an American quarter? (This is assuming you have the blank already made)

    I'd like to get a good estimate, but more importantly an idea of what numbers go into this estimate, i.e yield strength, coefficient of friction, etc.

    Thanks!
