I'm building a shearing and piercing die for a customer and I want to figure out the approximate force neccesary for this die. It's got four3/8" piercing punches and one 6" wide shear blade. This is using 1/8" thick AL stock.
So he's got a 20T press and I'm thinking we need a bigger press. So how do I figure out the tonnage needed for this die?
(remove the 4567 and it'll get to me)
