Flat Bar Hard-way & Easy-way Bending Calculator

One of the most common problems in the bending of flat bar profile is how to calculate the minimum bending radius (with hard-way & easy-way, Y-Y Axis (Weak), X-X Axis (Strong))and how much force is needed to bend them, so as to select the appropriate profile bending machine for bending.
Determining the appropriate bending process based on the minimum bending radius from the beginning of the project usually requires repeated calculations, which requires a lot of extra work from designers and operators. In order to obtain reliable values, various calculations and tests are required, which wastes a lot of time and materials.

This professional tool calculates bending parameters for 245MPa yield strength flat bar profile, supporting both stretch bending and profile roll bending processes. Simply enter the profile width to instantly get thickness, minimum bend radius, section modulus, and profile bending machine recommendations – all in one streamlined interface for efficient production planning.

How to calculate the minimum bending radius and select the best flat bar profile bending process

With this free online tool, we can quickly obtain the minimum bending radius and required bending force for two common bending processes from the flat bar profile bending calculation results.

You only need to select the bending process: roll bending or stretch bending, and then enter the width of the flat bar profile. The calculator will output the minimum bending radius and other important parameters. The calculator calculates the results of two bending methods in the roll bending process: X-X aixs bending (hard-way), Y-Y aixs bending (easy-way).
