Maximum Shear Force given Shear Applied to Punch or Die Solution

STEP 0: Pre-Calculation Summary
Formula Used
Maximum Shear Force = Perimeter of Cut*Stock Thickness*(Stock Thickness*Punch Penetration as Fraction)/Shear on the Punch
Fs = Lcut*t*(t*p)/tshear
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.
Perimeter of Cut - (Measured in Meter) - Perimeter of Cut is the perimeter of the punched product.
Stock Thickness - (Measured in Meter) - Stock Thickness 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
Perimeter of Cut: 616.6667 Millimeter --> 0.6166667 Meter (Check conversion here)
Stock Thickness: 8.99 Millimeter --> 0.00899 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
Fs = Lcut*t*(t*p)/tshear --> 0.6166667*0.00899*(0.00899*0.499985)/0.001599984
Evaluating ... ...
Fs = 0.0155743961154421
STEP 3: Convert Result to Output's Unit
0.0155743961154421 Newton --> No Conversion Required
FINAL ANSWER
0.0155743961154421 0.015574 Newton <-- Maximum Shear Force

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 = Perimeter of Cut*Stock Thickness*(Stock Thickness*Punch Penetration as Fraction)/Shear on the Punch
Shear on Punch or Die
Go Shear on the Punch = Perimeter of Cut*Stock Thickness*(Stock Thickness*Punch Penetration as Fraction)/Maximum Shear Force
Stock Thickness when Shear used on Punch
Go Stock Thickness = sqrt((Maximum Shear Force*Shear on the Punch)/(Perimeter of Cut*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 Perimeter of Cut = (Maximum Shear Force*Shear on the Punch)/(Punch Penetration as Fraction*Stock Thickness^2)
Penetration of Punch as Fraction
Go Punch Penetration as Fraction = (Maximum Shear Force*Shear on the Punch)/(Perimeter of Cut*Stock Thickness^2)
Punch Load
Go Punch Load = Perimeter of Cut*Bar Thickness*Strength Coefficient

Maximum Shear Force given Shear Applied to Punch or Die Formula

Maximum Shear Force = Perimeter of Cut*Stock Thickness*(Stock Thickness*Punch Penetration as Fraction)/Shear on the Punch
Fs = Lcut*t*(t*p)/tshear

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?

Maximum Shear Force given Shear Applied to Punch or Die calculator uses Maximum Shear Force = Perimeter of Cut*Stock Thickness*(Stock Thickness*Punch Penetration as Fraction)/Shear on the Punch to calculate the Maximum Shear Force, The Maximum Shear Force given Shear applied to Punch or Die is that force which is required to cut the given part out of blank when shear is applied on punch.
