PRU-088Heuristic screen

Material unsuited to cutting process

Sheet metal · Laser cutting · Plasma cutting · Flame cutting

Scope and limits

Material metadata vs process: copper/brass (reflective) and galvanised stock on laser, aluminium note, flame cutting only for carbon steel. Not geometry based. Sources: Laser Focus World, Xometry, Piranha Fab.

Standards and references

No standards reference is assigned to this check. The scope described above applies.

STEP examples for this check

Laser cutting · CC0-1.0

Copper plate on a laser

Model example

The STEP file declares the material "Copper CW004A". Copper is highly reflective: CO2 lasers risk back-reflection damage and only tuned fibre lasers cut it reliably. The geometry itself is fine.

Dimensions (approx.): 100 × 60 × 3 mm

Expected check result

PRU-088 should warn about the reflective material (read from the file, not the request).
