钣金折弯中性因子（K 因子）

数据来源：E:\FDM\折弯中性因子\折弯中性因子.xlsx（作者：光軍）
适用版本：UG NX 折弯系数表

![[Pasted image 20260707092829.png]]

什么是 K 因子

钣金折弯时，材料内侧受压、外侧受拉，中间有一层既不受压也不受拉的"中性层"。中性层的位置用 K 因子 表示：

K = 中性层到内表面的距离 / 材料厚度
  • K = 0 → 中性层在内表面（材料被完全压缩）
  • K = 0.5 → 中性层在正中间（理想情况）
  • K 越大 → 中性层越靠近外表面，展开长度越长

综合表：R/T ↔ 材料 K 值 + K1/K2 通用值
