Like any company, Lockheed Martin is always looking for ways to increase efficiency. Recently, this leader in aerospace, defense and advanced technology automated the process of painting F-35 Lightning II jets at its Raleigh, NC, plant. Lockheed Martin did this to save time, improve process control and protect workers from potentially harmful paint fumes.

The F-35 jets are now painted in robotic workcells that are programmed using DELMIA simulation software by Dassault Systèmes. As long-time users of DELMIA simulation products, Lockheed Martin engineers were already familiar with the software, making it easy for them to move into robot support roles.

Lockheed Martin uses the software to verify that robots reach all the painting positions while avoiding any collisions.

DELMIA allows manufacturers in any industry to virtually define, plan, create, monitor and control all production and assembly processes. The software helps companies maximize production efficiency, lower cost, improve quality and reduce time to market. DELMIA also offers a collaborative platform throughout the entire production process for engineers of all disciplines and suppliers.

Currently, Lockheed Martin uses the software in two different automated paint cells, both configured on moving rail systems. A three-robot cell is dedicated to painting the aircraft exterior, and a two-robot cell is configured to handle a variety of F-35 components.

The robot programming software has an enhanced Cenit Fastsurf feature, which gives Lockheed Martin greater painting control and more options. Fastsurf lets the company easily modify existing painting programs, as well as paint different mixes of components at different times. In addition, Fastsurf lets Lockheed Martin adapt to a part change by simply plugging a new parameter into the setup strategy.

Equally important, Fastsurf lets Lockheed Martin monitor the thickness of coatings through a query option at any point in the application. Applying coatings at the correct thickness is critical to ensuring that aircraft meet design requirements.

“Their [Lockheed Martin] in-depth experience in robotic off-line programming was key in shaping a production-hardened solution with aerospace accuracy,” says Niall Cullen, Cenit account manager.

Other key features of DELMIA are an intuitive 3D user interface and a use-only Web connection. The interface improves production process efficiency by lowering costs and reducing errors. Manufacturers use the Web connection for authoring and collaborating on manufacturing processes.
