In reality, plastic deformation shifts the neutral axis inward toward the radius. DIN 6935 provides specific guidelines for choosing the
The DIN 6935 standard is a cornerstone of precision in sheet metal fabrication. For engineers, designers, and fabricators, obtaining and studying the official is an investment in quality, safety, and professional reliability. It serves not only as a specification but also as a guide for best practices.
: Many international manufacturing contracts—especially in automotive, aerospace, and heavy machinery—explicitly mandate parts be engineered according to DIN 6935. 5. Implementation in CNC and Press Brake Programming Din 6935 Standard Pdf
It is crucial to use the most current version of a standard for legal and technical compliance. The current revision is . This version supersedes and replaces several earlier editions:
DIN 6935 is a technical standard developed by the German Institute for Standardization ( Deutsches Institut für Normung ). It regulates the calculation of flat lengths for bent sheet metal components made of steel, aluminum, and other metals. In reality, plastic deformation shifts the neutral axis
: For best results, bending should ideally be performed transverse (perpendicular) to the rolling direction of the steel to avoid structural failure. Calculating Developed Length One of the primary uses of DIN 6935 is calculating the stretched length
Software like SolidWorks, Autodesk Inventor, and Trumpf TruTops require precise bend deduction tables or formulas. Engineers reference the PDF to input exact DIN-compliant lookup charts. It serves not only as a specification but
-factor represents the ratio of the distance of the neutral axis from the inner surface to the material thickness. If the bending radius -factor is used to calculate the correction value. Large Radius Rule: If the bending radius , the position of the neutral axis is considered to be at , meaning the -factor equals 1. Summary of Key DIN 6935 Parameters Description Importance Material Thickness Core determinant of elongation Internal Bending Radius Prevents cracking/fracture Bending Angle Defines the shape Correction Value Determines final flat size How to Find the DIN 6935 Standard PDF
Some experts note that while widely used, it can be less precise for complex geometries compared to the Oehler method in specific software applications. Where to Access the PDF
