  3. 3

    See BA + flat pattern

    Bend allowance + flat layout length.

Frequently Asked Questions

What is K-factor?
Ratio of distance from inner surface to neutral axis vs material thickness. Material- and process-dependent. Aluminum soft: 0.33-0.40. Steel: 0.40-0.45. Stainless: 0.45-0.50.
Bend allowance vs bend deduction?
BA = arc length along neutral axis. BD = how much material to subtract from leg-sum to get flat pattern. Both methods give the same flat length, just different formulas.
Inner radius minimum?
Rule: minimum inner radius = thickness for soft materials, 1.5-2× thickness for hard. Below minimum = cracking. Stainless 304: typically 1.5×T minimum.
