Distinguish sheet ripping from rectangle nesting.
Which cutting model should be used for long strips?
Use the matching calculator
Use this decision sequence
- Keep full source sheet length when producing long strips.
- Deduct the total width trimmed from both source edges.
- Count strip widths with kerf along the source width.
- Use two-dimensional nesting only when the required parts have finite lengths and a compatible layout.
Keep the quantities distinct
| Quantity or assumption | How to use it |
|---|---|
| Strip ripping | One width allocation, each strip retains sheet length. |
| Uniform rectangle grid | Counts finite rectangular pieces in two orientations. |
| Arbitrary nesting | Requires a different placement algorithm. |
Worked comparison
A 1.20 m wide and 2.40 m long sheet with 0.02 m total edge trim, 0.10 m strips and 0.003 m kerf yields 11 full-length strips. Each sheet provides 26.4 m of strip, so 30 m needs 2 sheets.
Check before using the estimate
A source sheet’s gross area alone cannot establish long-strip cutting yield.
