The punch force required to punch a piece of sheet metal can be estimated from the following equation: [4] F = 0.7 t L ( U T S ) {\displaystyle F=0.7tL(UTS)} Where t is the sheet metal thickness, L is the total length sheared (perimeter of the shape), and UTS is the ultimate tensile strength of the material.
