π（pi）=3.141593
Punching force(kN)=
(B-A) x 2 + A x π x Material Thickness(mm) x Tensile strength(N/m㎡) ÷1000
Calculation result(kN)
*The punching force varies depending on the quality of the material and the processing conditions. Please use them as reference values.
*The values after the decimal point for short and long sides are not reflected in the calculation.
