How To Use Bend Allowance Data?
Example 1 – Bending 1mm mild steel in a 6mm V die
If（f）= Elongation factor
If（d）= Blank development size
d=(20+40)-2f
d=60-(2×0.87)
d=58.26mm
The following tables show the elongation factor（f）of mild steel, stainless steel and aluminium during a 90° bend.
- V = V-width (mm)
- t = material thickness (mm)
- f = bend allowances (mm)
