From laser power, focal length, cutting speed and material type, estimates maximum cutting depth, spot diameter and power density using the line-energy method.
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Cutting depth | d ∝ P/(v·kerf width) | Laser cutting |
| Power density | I = P/(πr²) at focal spot | Laser optics |
| Focal position | ±0.5 mm focal offset matters | Process specification |
| Assist gas | O2 boosts speed; N2 oxide-free | Assist gas selection |
| Piercing time | 0.5–3 s pulse piercing | Process parameter table |
| Heat-affected zone | HAZ 0.1–0.5 mm thin plate | Quality assessment |
