NADCAP Accreditation and Laser Cutting: What It Does and Does Not Cover

Generally no, because NADCAP does not maintain a special process commodity for conventional profile laser cutting. NADCAP, administered by the Performance Review Institute, accredits defined special processes such as heat treating, chemical processing, coatings, nondestructive testing, welding, and materials testing, each against published audit criteria. Ordinary laser cutting of a blank or detail part to a drawing is treated as a conventional manufacturing operation governed by the shop's quality system, which for aerospace means AS9100, not a NADCAP accreditation. When you see a shop marketing NADCAP and laser cutting together, dig one level deeper: usually the shop holds NADCAP for an adjacent process it performs, like heat treating or chemical processing the parts after they are cut, and the marketing has blurred that into an implied accreditation for cutting. There are edge cases where laser-based operations intersect with an accredited commodity, for instance laser welding falls under the NADCAP welding commodity, but that is welding, not cutting. The correct mental model is that NADCAP accredits what happens to the edge and the metallurgy around the cut, while AS9100 governs the cutting operation. Ask precisely which commodity the accreditation covers and verify it in eAuditNet rather than accepting a general NADCAP claim tied to cutting.

It depends on what the engineering requires after the cut, and the common ones are predictable. Removing the recast layer and heat-affected zone by chemical milling or chemical etch falls under NADCAP chemical processing, audited to the AC7108 checklist family, and the same commodity covers passivation of stainless and many surface treatments. If the part is heat treated after cutting to set or restore mechanical properties, that operation needs NADCAP heat treating under AC7102, including the pyrometry requirements of AMS2750 for furnace control. If a fatigue-critical or fracture-critical cut edge must be inspected for microcracking, fluorescent penetrant inspection or other nondestructive testing requires NADCAP NDT accreditation in the relevant method under the AC7114 series. Coatings applied after cutting bring in the coatings commodity. The pattern is that the laser produces a pre-form under AS9100, then each downstream special process must be performed by a line, in-house or subtier, that holds the matching NADCAP accreditation. As a buyer you should map your part's routing, identify every special process step, and confirm accreditation at each one. Missing accreditation on a single special process step can cause the prime contractor to reject the lot regardless of how good the cut was.

Use eAuditNet, the Performance Review Institute database that lists every NADCAP-accredited supplier, the specific commodities they hold, the scope of each accreditation, and the expiry dates. Unlike an ISO certificate that a shop can simply email you, NADCAP accreditation is granted per process and re-audited on a merit-based interval, commonly 12 to 24 months, with poor audit performance shortening the cycle and strong performance lengthening it, so currency genuinely matters and is worth checking against the live database. Search the supplier by name, confirm the commodity you care about appears, and read the scope, because a shop can hold heat treating accreditation while having nothing for chemical processing, and those are not interchangeable. Full eAuditNet search access is typically reserved for PRI subscribers and the prime contractor members, so if you do not have direct access, require the supplier to provide a current eAuditNet scope printout or grant you visibility, and treat reluctance as a red flag. Match the listed accreditation precisely to the special process your laser-cut part needs, verify the accreditation has not lapsed, and confirm the audit covers the exact method, for instance the specific NDT technique or the chemical processing operation, rather than accepting a general NADCAP claim.

Probably not, and requiring it can needlessly shrink your supplier pool and raise your price. If your part is a laser-cut blank or pre-form delivered to print with no controlled special process in its routing, the credential that matters is AS9100 Rev D, which governs the quality system, configuration control, traceability, and first article inspection for the cutting operation. NADCAP would only become relevant if the part definition adds a special process such as post-cut heat treatment, chemical milling to remove the recast layer, passivation, or NDT of the edge. Over-specifying NADCAP for a plain cutting job is a common procurement mistake: it implies a requirement that does not exist for the operation, it disqualifies perfectly capable AS9100 laser shops, and it can confuse suppliers into making accreditation claims that do not actually apply to cutting. The disciplined approach is to read the drawing and the prime's flowdown, identify whether any genuine special process is called out, and require NADCAP only for those specific steps performed by whoever performs them. For the cutting itself, qualify the shop on AS9100, its laser process capability, and material traceability. That gives you a properly controlled part without paying for an accreditation the operation does not require.
