Penetration of Punch as Fraction Solution

STEP 0: Pre-Calculation Summary
Formula Used
Punch Penetration = (Maximum Shear Force*Shear on Punch)/(Cutting Perimeter*Thickness of Stock^2)
p = (Fs*tsh)/(Lct*tstk^2)
This formula uses 5 Variables
Variables Used
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.
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.
STEP 1: Convert Input(s) to Base Unit
Maximum Shear Force: 0.015571 Newton --> 0.015571 Newton No Conversion Required
Shear on Punch: 1.599984 Millimeter --> 0.001599984 Meter (Check conversion ​here)
Cutting Perimeter: 615.66 Meter --> 615.66 Meter No Conversion Required
Thickness of Stock: 9 Millimeter --> 0.009 Meter (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
p = (Fs*tsh)/(Lct*tstk^2) --> (0.015571*0.001599984)/(615.66*0.009^2)
Evaluating ... ...
p = 0.000499581315805622
STEP 3: Convert Result to Output's Unit
0.000499581315805622 Meter -->0.499581315805622 Millimeter (Check conversion ​here)
FINAL ANSWER
0.499581315805622 0.499581 Millimeter <-- Punch Penetration

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 Penetration of Punch as Fraction?

Penetration of Punch as Fraction calculator uses Punch Penetration = (Maximum Shear Force*Shear on Punch)/(Cutting Perimeter*Thickness of Stock^2) to calculate the Punch Penetration, The Penetration of Punch as Fraction formula is defined as the penetration of the punch relative to the stock thickness. Punch Penetration is denoted by p symbol.
