Punch Load Solution

STEP 0: Pre-Calculation Summary

Formula Used

Punch Load = Cut Perimeter*Bar Thickness*Strength Coefficient
L_punch = L_ct*t_bar*S_c
This formula uses 4 Variables

Variables Used

Punch Load - (Measured in Newton) - Punch Load is the force exerted by the punching machine.
Cut Perimeter - (Measured in Meter) - Cut Perimeter is the perimeter of the punched product.
Bar Thickness - (Measured in Meter) - Bar Thickness refer to the thickness of a bar-shaped object, such as a metal bar or a structural element in a construction project.
Strength Coefficient - Strength Coefficient is a measure of strain capacity.

STEP 1: Convert Input(s) to Base Unit

Cut Perimeter: 615.6667 Millimeter --> 0.6156667 Meter (Check conversion here)
Bar Thickness: 0.003 Millimeter --> 3E-06 Meter (Check conversion here)
Strength Coefficient: 9112.5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_punch = L_ct*t_bar*S_c --> 0.6156667*3E-06*9112.5

Evaluating ... ...

L_punch = 0.01683078841125

STEP 3: Convert Result to Output's Unit

0.01683078841125 Newton --> No Conversion Required

FINAL ANSWER

0.01683078841125 ≈ 0.016831 Newton <-- Punch Load

Flow Stress

Go Flow Stress = True strain^Strain Hardening Coefficient*Strength Coefficient

Punch Load

Go Punch Load = Cut Perimeter*Bar Thickness*Strength Coefficient

Modulus Method

Go Modulus Method = Volume of Casting/Surface Area Of Casting

Tolerance

Go Tolerance = (0.45*Diameter^(1/3))+(0.001*Diameter)

Height of Nugget

Go Height of Nugget = 2*(Width-Indentation Load)

Draw Ratio

Go Draw Ratio = Blank Diameter/Cup Diameter

< 8 Punch Operation Calculators

Punching Force for Holes Smaller than Sheet Thickness

Go Punching Force or Load = (Punch or Ram Diameter*Blank or Sheet Thickness*Tensile Strength)/(Punch or Ram Diameter/Blank or Sheet Thickness)^(1/3)

Maximum Shear Force given Shear Applied to Punch or Die

Go Maximum Shear Force = Cut Perimeter*Thickness of Stock*(Thickness of Stock*Punch Penetration as Fraction)/Shear on the Punch

Shear on Punch or Die

Go Shear on the Punch = Cut Perimeter*Thickness of Stock*(Thickness of Stock*Punch Penetration as Fraction)/Maximum Shear Force

Stock Thickness when Shear used on Punch

Go Thickness of Stock = sqrt((Maximum Shear Force*Shear on the Punch)/(Cut Perimeter*Punch Penetration as Fraction))

Blank Size when there is Corner Radius on Punch

Go Blank Diameter = sqrt(Outer Shell Diameter^2+4*Outer Shell Diameter*Shell Height-0.5*Corner Radius on Punch)

Perimeter of Cut when Shear is Applied

Go Cut Perimeter = (Maximum Shear Force*Shear on the Punch)/(Punch Penetration as Fraction*Thickness of Stock^2)

Penetration of Punch as Fraction

Go Punch Penetration as Fraction = (Maximum Shear Force*Shear on the Punch)/(Cut Perimeter*Thickness of Stock^2)

Punch Load

Go Punch Load = Cut Perimeter*Bar Thickness*Strength Coefficient

Punch Load Formula

Punch Load = Cut Perimeter*Bar Thickness*Strength Coefficient
L_punch = L_ct*t_bar*S_c

What is a punching machine?

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.

How to Calculate Punch Load?

Punch Load calculator uses Punch Load = Cut Perimeter*Bar Thickness*Strength Coefficient to calculate the Punch Load, Punch Load is the force exerted by a punching machine. It is the amount of force exerted by the punch onto the target object or surface. Punch Load is denoted by L_punch symbol.

How to calculate Punch Load using this online calculator? To use this online calculator for Punch Load, enter Cut Perimeter (L_ct), Bar Thickness (t_bar) & Strength Coefficient (S_c) and hit the calculate button. Here is how the Punch Load calculation can be explained with given input values -> 0.016858 = 0.6156667*3E-06*9112.5.
