Calculating cutting force for slot sheet metal.
1kn 112 tons station size land distance the larger the perimeter of the cut hole the larger the tonnage required.
P s horsepower at the cutting tool.
In this article we will discuss various sheet metal cutting operations and their application.
Q metal removal rate.
Ultimate tensile strength psi.
Shape a dimension ld land distance.
Die edge radius in.
F r radial force.
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 it s 304 steel then the shear force is 141 2 282 tons.
Sheet metal cutting occurs due to shearing forces acting on the metal through the edges of the punch and die.
F t tangential force.
If cutting the q235 steel plate with 10mm thickness and 6000mm length the shear force is 10 6000 23 5 1410000 n 141 tons.
You can calculate the punching tonnage been required with the help of the following punching force calculation formula blanking force formula.
Punching force calculation formula.
Sheet metal cutting operations involve the removal of the material from larger sheets.
Cm 3 min t cutting time.
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.
