Bend deduction and outside flange dimensionsA schematic 90-degree bend. Outside dimensions A and B end at the virtual sharp, where the extended outer faces meet. Subtract bend deduction BD from A plus B to obtain flat length L. Dashed lines extend the outer faces; the orange dot marks their virtual intersection.L = A + B − BDABVirtualsharpOutside dimensions / 90° schematic

K-factor and the neutral axisSchematic cross-section of a 90-degree sheet-metal bend. K equals neutral-axis depth t divided by material thickness T. R is the finished inside bend radius. The orange dashed line marks the neutral axis. Diagram proportions are illustrative, not a preview of entered measurements.K = t / TTtRNeutralaxist: neutral-axis depth / T: thicknessR: inside bend radius / Schematic

Sheet metal length, width and thicknessA solid rectangular sheet in perspective. L is length, W is width and T is thickness. Single-sheet mass equals L times W times T times material density rho, with dimensions in metres and density in kilograms per cubic metre. The thickness is exaggerated for clarity.m = L × W × T × ρLWTSolid rectangular sheet / Schematic
