Parts are sorted from longest to shortest. The algorithm places each part in the best-fitting opened board, then chooses a new stock option if needed. Two stock-selection priorities are compared by cost and total length. Kerf and safety allowance are charged for every part, including the final cut; this is conservative when an end can be reused without cutting. Stock quantities are finite.
Calculation method
L₁ ≥ L₂ ≥ …; min(Sᵢ − Σ(Lⱼ + k + a) − 2t)Measure. Calculate. Build.
- Use actual dimensions and split complex rooms into rectangles.
- Allow for cuts, joints and package sizes. Compare stock formats.
- Combine your results in a shopping list you can save and print.
