Linear cutting guide
Linear cutting is a one-dimensional packing problem
Each requested length must be assigned to a stock length without exceeding available material. Kerf is consumed between consecutive pieces.
Why longest-first often works
Placing long cuts first reduces the chance that large pieces become impossible to place later. Best-fit can then use remaining gaps for shorter pieces.
Check real machine allowances
End trims, clamping zones and machine-specific minimum remnants are not automatically known by a generic optimizer. Add conservative allowances when needed.
