For instance, 0.062-in.-thick cold-rolled steel will bottom once the punch nose is 0.074 to 0.078 in. from the bottom of the V die.
Webb13 feb. 2003 · Coining requires more tonnage than bottom bending. Coining also requires that the punch tip be sharp (less than 63 percent of the material thickness) to produce a 90-degree bend—the sharper the better. It also requires that the material thickness neutral axis be penetrated, where thinning of the material is necessary.
