Bending Calculator

Bending Calculator helps estimate sheet metal flat lengths using calculation principles based on DIN 6935.

Enter sheet thickness, inside radius, side lengths, and bend angles to calculate the developed length of a bent sheet metal profile. Each bend displays the K-factor used in the calculation, with options for manual radius and K-factor overrides.

Features:
Developed length calculation for sheet metal bending
Support for multiple bends
Per-bend inside radius and K-factor values
Manual override options
Metric and inch input support
Dimensioned profile preview
K-factor calculator
Minimum recommended radius reference for steel, stainless steel, and aluminium

Bending Calculator is intended as a practical workshop and engineering aid for estimating flat pattern lengths. Results should be verified according to your tooling, material, and production requirements before manufacturing.
