Punching holes in steel :Chart and Calculator

To calculate the force to punch holes in metal you determine the cross section in shear and multiply it by the shear strength of the metal. The formula is Perimeter times thickness times shear. For round holes in steel this is Diameter * PI * 30. Thirty tons being the approximate shear strength of mild steel plus an allowance for friction. Sheet Metal Punching Rules - Hampshire, UKSo, for example a diameter 5mm punch with a 0.2mm die clearance die will produce a hole that is diameter 5mm on the punch side of the sheet and diameter 5.2mm on the die side of the sheet.
