Calculate the required force to deep draw a piece of sheet metal based on the drawing ratio, sheet thickness, and the ultimate tensile strength of the material.

The drawing ratio is a measure of the severity of the drawing operation and is the ratio of the initial blank diameter to the punch diameter.

For a given material, the limiting drawing ratio (LDR) is a measure of that material's deep drawability and is calculated from
the largest blank that can be completely deep drawn for a given punch diameter.

The amount of draw can also be represented as the percent reduction of the blank diameter.

The calculated tonnage can be used for the selection of a machine to perform the deep drawing operation. 

We also have Air Bending Force, Bend Allowance, Springback and Wipe Bending Force Calculators.

Enter your sheet thickness blank diameter and punch diameter then select your material type and finally enter a safety factor, units can be selected as required.
