Workflow map
Start at the stage that matches the job in front of you; each stage links directly to the calculators and lookup tools that support it.
- 1
Calibrate bend data
Back-solve K-factor, bend allowance and bend deduction before reusing shop settings.
- 2
Flatten the part
Generate box/tray blanks, cone blanks and duct transition estimates.
- 3
Check shop limits
Look up gauge thickness, screen press-brake tonnage and estimate powder coating, anodizing or electroplating before releasing the blank.
Tools in this workflow
Calculators come first, followed by lookup tools and reference pages when this workflow needs tabular data.
Calculator K-Factor Back-solve sheet-metal K-factor from measured bend data, compare copper/metal starter bands, and report bend deduction, setback and neutral-axis offset. Calculator Bend Allowance Bend allowance, deduction and setback from angle, radius, thickness and K-factor. Calculator Bend Deduction Flat blank length, bend deduction and normalized bend deduction chart for press-brake layout. Calculator Press Brake Tonnage Air-bending press force from thickness, bend length, V-die opening and material strength. Calculator Box Flat Pattern Open sheet-metal box or tray blank size, bend-line offsets, bend deduction, bend allowance and corner relief from base size, side height, radius and K-factor. Calculator Cone Flat Pattern Conical frustum flat pattern radii, sector angle, slant height, arc lengths and blank area from diameters and height. Calculator Duct Transition HVAC duct reducer and transition length, taper angle, inlet/outlet velocity, velocity pressure change and sheet-metal blank area from rectangular or round outlet geometry. Calculator Powder Coating Coverage Powder coating coverage, pounds to plan, net fresh powder and material cost from area, film thickness, powder SG, transfer efficiency and reclaim. Calculator Anodizing Amp-Hour Anodizing current, amp-hours, runtime, rectifier utilization and oxide mass from aluminum area, film thickness, current density and efficiency. Calculator Electroplating Thickness Electroplating thickness, time, amp-hours, current, rectifier utilization and deposited metal mass from area, current density, efficiency and Faraday material data. Lookup tool Sheet Metal Gauge Finder Find the nearest sheet-metal gauge by material and target thickness, with inch, mm, mil and weight references. Reference Sheet metal gauge chart
