1. What is Perimeter of Cut?

Perimeter of Cut is the total length of the cut edge produced in a material during the punching process. It represents the boundary length where the material is separated during the punching operation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( L_{cut} \) — Perimeter of Cut (m)
• \( P_s \) — Stripper Force (N)
• \( K \) — Stripping Constant
• \( t_{blank} \) — Blank Thickness (m)

Explanation: The formula calculates the perimeter of cut by dividing the stripper force by the product of stripping constant and blank thickness.

3. Importance of Perimeter of Cut Calculation

Details: Accurate calculation of perimeter of cut is crucial for determining the appropriate stripper force required in punching operations, ensuring proper material separation and tool design.

4. Using the Calculator

Tips: Enter stripper force in Newtons, stripping constant (dimensionless), and blank thickness in meters. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is Stripper Force?
A: Stripper Force is the force applied by a stripper plate or stripper ring to remove the formed part from the punch after the forming operation is completed.

Q2: What is Stripping Constant?
A: Stripping Constant is an empirical constant used to calculate stripping force, which varies based on material properties and tooling conditions.

Q3: How is Blank Thickness measured?
A: Blank Thickness is the thickness of the material being worked on before any operations are performed on it, typically measured in millimeters or meters.

Q4: What factors affect the Stripping Constant?
A: The stripping constant depends on material type, tool design, lubrication, and specific punching conditions.

Q5: When is this calculation most important?
A: This calculation is particularly important in precision punching operations where accurate force calculations are needed for proper tool design and process optimization.
