Capacity chart for air bending
The given data has been calculated based upon bending material with a tensile strength of δb=420 MPa over a length of 1m.
Internal radius R
The internal radius R corresponds to approximate 16% of the die opening V.
Recommended die opening V for air bending
|Material thickness (t)||0.5~2.5mm||3~8mm||9~10mm||>12mm|
|Die opening (V)||6 × t||8 × t||10 × t||12 × t|
