Kerf Bend Calculator
The Kerf Bend Calculator is a vital tool used in metal fabrication, specifically in sheet metal bending operations. It aids in determining the Kerf Bend Allowance (KBA), an essential factor influencing accurate bending dimensions in metalwork. This tool calculates the required adjustments to compensate for material thickness lost during the bending process.
Formula of Kerf Bend Calculator
The Kerf Bend Allowance (KBA) formula stands as:
Kerf Bend Allowance (KBA) = (π * R * B) / 180
Here’s a breakdown of the formula:
- KBA refers to the kerf bend allowance, aligning with the material thickness units.
- π (pi) approximates 3.14159.
- R represents the inside bend radius, measured in the same units as the material thickness.
- B signifies the bend angle in degrees.
Table of General Terms and Conversions
| Term | Description |
|---|---|
| Inside Bend Radius | Radius of the bend die/tooling in material thickness units |
| Bend Angle | Angle at which the material is bent in degrees |
| Material Thickness | Thickness of the material being bent |
This table provides a quick reference for essential terms and their descriptions, aiding users in understanding and applying the Kerf Bend Calculator more effectively.
Example of Kerf Bend Calculator
Let’s consider a scenario: A metal sheet with a thickness of 2mm undergoes bending with an inside bend radius of 5mm and a bend angle of 90 degrees. The Kerf Bend Calculator accurately calculates the Kerf Bend Allowance to ensure precise bending dimensions.
