Grievesk Bend: a press-brake calculator with a CAD reality check
This Italian-language tool estimates sheet-metal bending force, geometry and flat-pattern dimensions from material and workshop settings.
- For
- Sheet-metal fabricators and CAD technicians
- Worth noticing
- It distinguishes air bending, rotary-die bending, bottoming and wiping, and compares CAD bend deduction with workshop estimates.
Field notes
The form combines material presets from S235 steel through stainless steel and aluminum with a custom tensile-strength input. The visible example uses a 2 mm sheet and shows a 96.40 mm flat-pattern result, while the CAD-versus-workshop panel compares radius, K-factor, bend deduction and laser-cut length. A recommendation in that same example tells users to set bend deduction, radius and K-factor to zero, so that advice should be checked rather than treated as validated guidance.
