If you're in steel construction or mechanical engineering, you've likely encountered the complexities of bending flat rolled steel. Getting the dimensions right before the first hit of the press brake is critical to avoiding waste and ensuring structural integrity. This is where the becomes an essential tool for your workshop or design office. What is the DIN 6935 Standard?

: Establishes minimum leg lengths for bent parts and notes that material thickness typically decreases by approximately 20% in the rounded portion of the bend. Technical Documents & Resources

-factor) that identifies the location of the neutral axis, which is typically taken as of the material thickness. DIN 6935 vs. Other Bending Standards Din 6935 Standard Pdf

: Defines permissible tolerances for both bending radii and the final angular positions of the bent sections.

To apply the standard correctly, you must understand its core geometric and material variables: The nominal gauge or thickness of the raw sheet metal. Inside Bend Radius (

Ensure the metal sheet has consistent thickness. This public link is valid for 7 days

According to the standard, final stretched lengths should generally be rounded to the nearest millimeter for practical manufacturing purposes. Practical Applications

Always generate a test flat DXF file and verify the math against a physical test bend to calibrate your specific shop machinery.

Sharp bends can cause cracking; the minimum bend radius should be respected.

DIN 6935 uses a variable ( v ) (also referred to in literature as the neutral axis shift factor). The standard defines ( v ) based on the ratio ( r/s ) (radius divided by thickness):
