How to Calculate Blanking Force - MechExtreme
Mar 31, 2020 · Here is a general formula for calculating the blanking force: Blanking Force = Perimeter of the Cut × Plate Thickness × Shear Strength. F = Pl × t × St. Hole perimeter is depend on hole shape as like - Hole perimeter (Round) (PL) = π × d. The method for estimating the perimeter of a shape relies on the shape in question.

Knowing the forming force necessary for carrying out a press blanking operation (shearing operation) is indispensable for selecting the press machine and for carrying out the die and punch design. The blanking force (P) is obtained using the following equation.
Punching Force Calculator & Formula (Online & Free)
Oct 23, 2024 · The basic formula for calculating the punching force (F) is ( F = K × L × t × τ ) where ( K ) is the safety factor, ( L ) is the perimeter length, ( t ) is the material thickness, and ( τ ) is the material’s shear strength.
Do you know how to calculate punching force and its application?
If you are making a round, square or other hole in a given thickness of metal, you must know the force required to make the hole in the steel. The required punching tonnage can be calculated with the help of the following punching force calculation formula (blanking force formula):
Calculating Cutting and Drawing Forces - MetalForming Magazine
Dec 1, 2009 · The generally accepted formula for predicting the maximum punch load is: F = S p dt, where F is the maximum punch force in pounds, S is the nominal tensile strength of the material being drawn (psi), d is the punch or cup diameter and t is the blank thickness. Thus, the force equals pressure times the cross-sectional area of the cup wall.
