Exacting Work, Uneven Results
Nutplate installation demanded precision at every handoff. Rivet height had to be exact, yet inconsistent placement forced operators to shave rivets manually and apply a corrosion-protection chemical film afterward.
The work was repetitive, time-consuming and difficult to staff. Employees needed intensive certification for each part they produced, documented their work as it happened and still faced recurring product inconsistencies.
Part variety sharpened the difficulty. The cell had to recognize 225 part styles and 28 possible nutplate configurations, then accommodate installation at two different pitches without sacrificing alignment or traceability.
- Exact rivet placement governed finished-part quality.
- Manual shaving added work, waste and chemical finishing.
- Lengthy certification made retention and staffing harder.
- High part variation demanded adaptable vision and tooling.
A Compact Cell Built Around Vision
The supplier and its integration partner condensed drilling, countersinking, rivet selection, nutplate verification, sealant application, installation and crimping into a single cell. That compact architecture removed work-in-progress stations while respecting limited floor space and budget constraints.
Development proceeded methodically. The team first used a complex curved part to develop and test vision-guided locating sequences, then added the drilling and riveting tools. Three robots coordinated around shared part features, with 3D vision repeatedly checking position, plane alignment, component identity and sealant application.
An operator still loaded the cart and entered the part number through the machine interface. The published account does not describe the commissioning schedule, cell-user training program or ongoing service arrangement, so those elements are not presented here as documented outcomes.
- Locate distinctive part features and correct plane alignment.
- Drill and countersink the rivet holes.
- Verify the nutplate, tooling and sealant application with vision.
- Coordinate rivet placement, installation and final crimping.
Less Labor, Faster Cycles, Tighter Consistency
The completed installation ran at 39 seconds per nutplate, cutting cycle time by 26 seconds. Required operators fell from three to one, and the compact cell produced a finished part without intermediate work-in-progress stations.
After just over one year in production, the supplier reported 97% consistency and described part inconsistencies as virtually eliminated. Consistent rivet installation also removed manual shaving and the related chemical-film application from the process.
The cell ultimately became central to production and operated 24 hours a day. The documented gains were specific: lower manual staffing, shorter cycles, less ancillary processing and more dependable output.
What This Evidence Means for Aerospace Buyers
This documented deployment shows that high-mix aerospace assembly can be a credible automation candidate when vision, tooling and process control are designed as one production system. It is an industry example analyzed by Service Robot Co., not a Service Robot Co. customer deployment or performance claim.
Service Robot Co. is a full-service, OEM-neutral commercial robot integrator for US businesses. We select equipment across manufacturers, arrange financing, manage robot deployment and integration, train operating teams and support deployed units through a nationwide US engineer network.
That lifecycle model gives aerospace manufacturers a single accountable vendor from free site assessment and commercial robot demo through go live support. A robot pilot program can establish fit before a broader commitment, while lease rental or sale, monthly payment programs and robot financing for small business can align acquisition with operating needs.
After commissioning, a robot maintenance service plan, remote triage, on-site dispatch and commercial robot repair service keep technical ownership clear. The practical lesson from this cell is not merely to buy robots. It is to engineer the entire application around part variation, quality gates, operator responsibilities and serviceability.
