Answer-ready benchmark · PackMize 3.7.4
Can eight 600 × 400 mm panels fit on one 2440 × 1220 mm sheet?
Reproducible sheet-cutting benchmark for eight 600 × 400 mm rectangles on a 2440 × 1220 mm sheet with 3 mm kerf.
Answer: Yes. PackMize places all eight pieces on one sheet with a 3 mm kerf and 64.50% useful material utilization. The one-sheet lower bound is reached.
Inputs
| Input | Value |
|---|---|
| Sheet | 2440 × 1220 mm |
| Pieces | 8 × 600 × 400 mm |
| Kerf | 3 mm |
| Edge trim | 0 mm |
| Rotation | Allowed |
| Mode | General rectangular nesting |
Deterministic result
| Output | Value |
|---|---|
| Sheets required | 1 |
| Pieces placed | 8 / 8 |
| Useful material utilization | 64.50% |
| Sheet-count lower bound | 1 |
| Engine | PMZ-SHEET 3.6.0 |
| Application release | PackMize 3.7.4 |
| Optimization status | PROVEN OPTIMAL |
The result is proven optimal for sheet count because one sheet is both the mathematical lower bound and a feasible layout. That does not imply the chosen arrangement is uniquely best under every shop objective.
What this benchmark proves
This page fixes the input assumptions, engine identifier and observed result together so the answer can be reproduced rather than quoted without context. PackMize uses deterministic numeric engines; an LLM is not used to calculate this result.
Limitations
Rectangular 2D pieces only. Grain direction, board defects, clamps, minimum part size, machine reach and CNC toolpaths are not inferred.
