When you bend a piece of sheet metal, the outside of the bend stretches, and the inside compresses. The neutral axis (where no stretching or compression occurs) shifts inward. DIN 6935 provides a scientifically validated method to locate that neutral axis using the . Din 6935 Standard Pdf
It outlines acceptable tolerances for both bending angles and radii, helping manufacturers maintain quality control during mass production. Modulus Metal Practical Review & Application Professional Review Summary It outlines acceptable tolerances for both bending angles
Bending angle (α), Material thickness (s), and the Internal Bending Radius (R). 3. Calculating the Bending Deduction Calculating the Bending Deduction 💡 : When selecting
💡 : When selecting a bending radius, always refer to the "bolded" values in the Scribd DIN 6935 Tables first. These are the preferred industry standards that offer the best balance between structural integrity and ease of manufacturing.
The standard also outlines how much the final bend can deviate from the design:
The primary objective of DIN 6935 is to find the Developed Length (
