K Factor Calculator

K-Factor Calculator

K-Factor Calculator is a utility tool developed to calculate the k-factor used in sheet metal bending operations in a fast, practical, and reusable way.

Enter your measurements and instantly see the calculated k-factor. Optionally, save the result in a table with material / thickness / radius / k-factor information for reuse in future designs.

The goal is to convert real production data obtained in the workshop or on-site into values that can be directly used in design processes.

Application Usage:

A sheet metal part with a known thickness, cut to a specific flat length to be used as the flat length, is bent once or twice.

After the bending operation, the bend dimensions and inner radius (r) measured directly from the part are entered into the application. Using these values, the actual k-factor is calculated.

The calculated value is then saved together with the material and thickness information for reuse in future designs, creating a reliable and consistent k-factor archive over time.

Benefits of This Approach:

-No dependency on theoretical tables,

-Values specific to your machine, tooling, and process,

-Repeatable and consistent bending results.

Key Features

K-Factor Calculation:

Calculate the k-factor using L1, L2 (optional L3), flat length (L), inner radius (r), and sheet thickness (t).

Record Table:

Create a structured archive by storing material + thickness + r + k-factor values.

Select & Export:

Select records individually or use “Select All” to export selected entries.

Share & QR Export:

Export selected records as text or generate QR codes for fast transfer between devices.

Import:

Restore records by pasting exported text or by scanning QR codes.

Conflict Management:

When a record with the same material and thickness already exists, choose to overwrite or skip.

Fast Workflow:

Tap a table row to automatically fill input fields and clearly see which record will be deleted before confirmation.

Who Is It For?

-Professionals working with sheet metal and bending operations,

-Manufacturing, design, and quality teams,

-Workshop and field users who need fast and reliable calculations.

Note: This application is a calculation and data management tool. Results may vary depending on measurement accuracy, material properties, and process parameters.
