1D Linear Cutting Optimizer

Best-fit decreasing for lumber, steel tube, aluminum extrusion, PVC, rebar, and other straight stock. Multiple stock lengths and reusable offcuts are supported. Miter/angle fields are printed as planning notes; they do not change straight-stock geometry.

Aluminum Extrusion Cut List Optimizer

Plan aluminum extrusion cuts using metric stock length, saw kerf, and best-fit decreasing optimization.

Preset guide

Aluminum extrusion cut list preset

Use this page for straight aluminum extrusion lengths. It plans stock usage and offcuts, but it does not validate slot orientation, end machining, tapping, deburring, or assembly design.

Extrusion-specific review

Profiles that look similar can be different series, slot size, finish, or wall thickness. Use material labels to keep incompatible stock separated.

Reusable offcutsUseful only if long enough for future frames.

Scope boundary

StockCut does not model tapped holes, brackets, corner connectors, end caps, or assembly clearance. Enter cut lengths after those decisions are made.

Common mistakes to avoid

  • Mixing different extrusion profiles in one run.
  • Forgetting end machining or cleanup allowance.
  • Using nominal frame outside dimensions as cut lengths without accounting for connectors.
  • Treating the cutting sequence as assembly instructions.
