How to calculate press machine tonnage?

Well, First get the Dia of material in inches = A

Get the thickness of material in inches = B

Now, Multiplier for M.s is 80 & for soft material like copper, brass, alluminium is 6 0.

now put the A X B X MULTIPLIER = TONNAGE

Example,

1 inch dia

5mm thickness

Material is M.S.

SO TONNAGE is : 1 x 0.1968 x 80 = 15.75 is tonnage required...

ENJOY TONNAGE FORMULA.
