If you punch round holes or square holes or some other forms of holes through a given thickness of metal you just want to know the force required to punch a hole in steel.

Calculating cutting force for slot sheet metal.

Sheet metal cutting occurs due to shearing forces acting on the metal through the edges of the punch and die. F r radial force. F t tangential force. Ultimate tensile strength psi.

Punching force calculation how to calculate punching force in tons punching force 25 x land distance x material thickness x material factor x shear factor note. If cutting the q235 steel plate with 10mm thickness and 6000mm length the shear force is 10 6000 23 5 1410000 n 141 tons. Punching force calculation formula. Cm 3 min t cutting time.

1 ton 8 90 kn. Shape a dimension ld land distance. F f feed force. P s horsepower at the cutting tool.

Variety of sheetmetal cutting operations are possible. In this article we will discuss various sheet metal cutting operations and their application. You can calculate the punching tonnage been required with the help of the following punching force calculation formula blanking force formula. Q metal removal rate.

P m horsepower at the motor. If it s 304 steel then the shear force is 141 2 282 tons. If it s q345 steel plate then the shear force should be 141 1 4 197 4 tons. 1kn 112 tons station size land distance the larger the perimeter of the cut hole the larger the tonnage required.
