FAT Checks for a Fiber Laser Cutting Machine: Turning Accuracy Claims into Pass/Fail Tests
A buyer's guide to defining practical factory acceptance test criteria for a fiber laser cutting machine, using catalog reference values as starting points rather than guarantees.
Before signing off on a fiber laser cutting machine, decide which measurements will count as pass or fail at the factory acceptance test, and write them into the purchase order. A useful starting point is the catalog reference value of ±0.001 in X/Y repositioning accuracy, but treat it as a reference only and ask the supplier to state the test method, material, thickness, and measurement instrument behind any figure offered for the supplied model.
For steel and aluminum work, ask for cut samples across the 3–12 kW power range offered, and agree on how edges, kerf, and dimensional repeatability will be judged. Within the 120 × 60 in processing area, specify where test cuts are made and whether repositioning is checked at multiple positions. Request that the same program and parameters be used for repeated runs so pass/fail depends on the machine, not operator adjustment.
Before requesting a quote, confirm with the supplier which acceptance tests they will run, who witnesses them, what records are provided, and how a failed check is corrected and retested.
