Maximum Shear Force given Shear Applied to Punch or Die Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Shear Force = Cut Perimeter*Thickness of Stock*(Thickness of Stock*Punch Penetration as Fraction)/Shear on the Punch
F_s = L_ct*t_stk*(t_stk*p)/t_shear
This formula uses 5 Variables

Variables Used

Maximum Shear Force - (Measured in Newton) - Maximum Shear Force is the max. force due to shearing between two planes.
Cut Perimeter - (Measured in Meter) - Cut Perimeter is the perimeter of the punched product.
Thickness of Stock - (Measured in Meter) - Thickness of Stock generally refers to the initial thickness of raw material or stock material before any machining or processing takes place.
Punch Penetration as Fraction - Punch Penetration as Fraction is the relative amount of punch which penetrates the work.
Shear on the Punch - (Measured in Meter) - Shear on the punch is applied during punching process on punch or die, to reduce the required shearing force.

STEP 1: Convert Input(s) to Base Unit

Cut Perimeter: 615.6667 Millimeter --> 0.6156667 Meter (Check conversion here)
Thickness of Stock: 8.9963 Millimeter --> 0.0089963 Meter (Check conversion here)
Punch Penetration as Fraction: 0.499985 --> No Conversion Required
Shear on the Punch: 1.599984 Millimeter --> 0.001599984 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_s = L_ct*t_stk*(t_stk*p)/t_shear --> 0.6156667*0.0089963*(0.0089963*0.499985)/0.001599984

Evaluating ... ...

F_s = 0.0155709409862928

STEP 3: Convert Result to Output's Unit

0.0155709409862928 Newton --> No Conversion Required

FINAL ANSWER

0.0155709409862928 ≈ 0.015571 Newton <-- Maximum Shear Force

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

Maximum Shear Force given Shear Applied to Punch or Die Formula

Maximum Shear Force = Cut Perimeter*Thickness of Stock*(Thickness of Stock*Punch Penetration as Fraction)/Shear on the Punch
F_s = L_ct*t_stk*(t_stk*p)/t_shear

Why Shear is provided on punch?

To reduce the required shearing force on the punch, for example to accommodate a large component on a smaller capacity punch press, shear is ground on the face of the die or punch. The effect of providing shear is to distribute the cutting action over a period of time depending on the amount of shear provided. Thus the shear is relieved of the punch or die face so that it contacts the stock over a period of time rather than instantaneously. It may be noted that providing the shear only reduces the maximum force to be applied but not the total work done in shearing the component.

How to Calculate Maximum Shear Force given Shear Applied to Punch or Die?
