GKN Aerospace

Robotic AI inspection of complex metallic parts

GKN Aerospace built a robotic inspection cell after tests detected more than 95% of defects

In progressCompany's own claim

Problem

Complex metal surfaces made small defects difficult to inspect consistently. Curved geometry complicated lighting and camera focus.

Approach

GKN Aerospace worked with university researchers on an ARM Institute-funded inspection system. Robots collected images under controlled lighting, and deep-learning methods assessed surface defects. GKN built the resulting inspection cell in a factory.

Results

above 95%defect detection rate reported for the development project by ARM InstituteCompany's own claim[1]
approximately one minuteinspection time per part reported for the development project by ARM InstituteCompany's own claim[1]

Takeaway

The project reported detection and inspection-speed results. Factory-wide financial returns remained projections.

The project funder reported detection above 95% and inspection at approximately one minute per part. It confirmed that GKN built a factory cell; the stated return on investment was expected rather than realized.
