Shear on Punch or Die Solution

STEP 0: Pre-Calculation Summary

Formula Used

Shear on Punch = Cutting Perimeter*Thickness of Stock*(Thickness of Stock*Punch Penetration)/Maximum Shear Force
t_sh = L_ct*t_stk*(t_stk*p)/F_s
This formula uses 5 Variables

Variables Used

Shear on Punch - (Measured in Meter) - Shear on Punch is the force or stress acting parallel to the cross-sectional area of the punch, typically encountered during a punching operation.
Cutting Perimeter - (Measured in Meter) - Cutting Perimeter is the process of cutting the outer edges of a sheet of metal to shape it according to a specific design or pattern.
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 - (Measured in Meter) - Punch Penetration is the depth to which a punch penetrates into a material during a punching or piercing operation.
Maximum Shear Force - (Measured in Newton) - Maximum Shear Force is the highest magnitude of force acting perpendicular to the cross-section of a material, causing shear stress and potentially leading to deformation or failure.

STEP 1: Convert Input(s) to Base Unit

Cutting Perimeter: 615.66 Meter --> 615.66 Meter No Conversion Required
Thickness of Stock: 9 Millimeter --> 0.009 Meter (Check conversion here)
Punch Penetration: 0.499985 Millimeter --> 0.000499985 Meter (Check conversion here)
Maximum Shear Force: 0.015571 Newton --> 0.015571 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_sh = L_ct*t_stk*(t_stk*p)/F_s --> 615.66*0.009*(0.009*0.000499985)/0.015571

Evaluating ... ...

t_sh = 0.00160127685910346

STEP 3: Convert Result to Output's Unit

0.00160127685910346 Meter -->1.60127685910346 Millimeter (Check conversion here)

FINAL ANSWER

1.60127685910346 ≈ 1.601277 Millimeter <-- Shear on Punch

Punching Force for Holes Smaller than Sheet Thickness

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

Blank Size when there is Corner Radius on Punch

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

Maximum Shear Force given Shear Applied to Punch or Die

Go Maximum Shear Force = Cutting Perimeter*Thickness of Stock*(Thickness of Stock*Punch Penetration)/Shear on Punch

Shear on Punch or Die

Go Shear on Punch = Cutting Perimeter*Thickness of Stock*(Thickness of Stock*Punch Penetration)/Maximum Shear Force

Stock Thickness when Shear used on Punch

Go Thickness of Stock = sqrt((Maximum Shear Force*Shear on Punch)/(Cutting Perimeter*Punch Penetration))

Perimeter of Cut when Shear is Applied

Go Cutting Perimeter = (Maximum Shear Force*Shear on Punch)/(Punch Penetration*Thickness of Stock^2)

Penetration of Punch as Fraction

Go Punch Penetration = (Maximum Shear Force*Shear on Punch)/(Cutting Perimeter*Thickness of Stock^2)

Punch Load

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

Shear on Punch or Die Formula

Shear on Punch = Cutting Perimeter*Thickness of Stock*(Thickness of Stock*Punch Penetration)/Maximum Shear Force
t_sh = L_ct*t_stk*(t_stk*p)/F_s

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 Shear on Punch or Die?

Shear on Punch or Die calculator uses Shear on Punch = Cutting Perimeter*Thickness of Stock*(Thickness of Stock*Punch Penetration)/Maximum Shear Force to calculate the Shear on Punch, Shear on Punch or Die is provided to decrease the shearing force required to cut the shape out of blank during punching.
