anvilfire〉189. 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.
MachineMfg〉2023529ヂ Thickness = 3mm. Shear Strength = 0.3447kn/mm 2. Punch Force (KN) = 80 x 3 x 0.3447 = 82.728 KN Convert into tonnage: 82.728 KN 9.81 = 8.43 Ton. For further information about shearing strength, including how to calculate it, you can refer to the Wikipedia article. The formula mentioned can also be applied as the cutting force formula

They progressed from the mechanical to the hydraulic to the electric
mindxmaster〉2021225ヂ Method #2: Dremel Tool. This method works for any saw, really. But for small holes in thin-gauge metal, a Dremel tool works fantastic. The tool is small enough to be controlled easily by hand and make accurate cuts. The same technique can be used with a larger circular saw, but youl probably get less accurate cuts and a coarser-looking hole.
