Free bend allowance calculator for sheet metal: thickness, inside radius, angle, and K-factor to compute bend allowance, outside setback, and bend deduction with scenario rows.
Fabrication note: This bend allowance calculator gives layout math for press-brake planning. Real flat patterns still depend on tooling, tonnage, grain direction, springback, and your shop’s empirical bend tables.
Summary: Enter material thickness, inside bend radius, bend angle, and K-factor. The tool returns bend allowance (BA), outside setback (OSSB), and bend deduction (BD) with scenario rows for tolerance and setup changes.
