钣金折弯回弹/过弯计算器

使用ASM回弹比 Ks = 4x³ − 3x + 1，基于材料、厚度和折弯半径预测回弹角度、折弯机过弯设定值和最终半径。

Large springback — high-strength or low-modulus material with a generous radius. Increase overbend and verify with a first-article part.

ASM springback-ratio model (ASM Handbook Vol. 14B): Ks = 4x≈ −3x + 1 with x = σy·R/(E·t). First-order estimate …"real springback also depends on tooling, friction, strain hardening and material-lot variation. Use the overbend angle as a starting setpoint and fine-tune with a first-article bend.
