coefficients depending on how sharp the bend is relative to the material thickness. Below is a reference chart adapted from the DIN 6935 guidelines: K-Factor ( Neutral Axis Shift Position Highly compressed; axis shifts far inward Standard sharp bend Medium bend radius Generous bend radius Large radius bending Neutral axis remains exactly in the center Limitations of the DIN 6935 Standard
The is an essential tool for any engineer or fabricator working with bent steel. It provides the mathematical foundation to move from a 3D bent model to a precise 2D flat pattern, ensuring quality, reducing scrap, and meeting tight tolerances. Din 6935 Standard Pdf
