Lockheed Martin expands robotic software use for F-35

The organisation, which is a long-term user of the Delmia manufacturing simulation software, also from Dassault Systèmes, says its manufacturing processes are now more efficient, in part as a result of harnessing a common interface across its Catia design and Delmia digital manufacturing solutions. Lockheed Martin spokesperson explains that it is using simulations to verify that the robots, which look after the paint and coatings processes, will reach all the painting positions, while avoiding collisions. He also says that, since the organisation was already familiar with the Catia interface, Lockheed Martin NC programmers were easily able to move into robot support roles, pick up the software and produce programs. Lockheed Martin currently employs the robotic solution in two automated paint cells, both configured on moving rail systems. A three-robot cell is dedicated to painting aircraft exteriors while a two-robot cell handles a variety of F-35 components. The spokesperson says that enhancements within the Delmia Cenit Fastsure software make it easier to modify existing robot programs as part of continuous improvement. Previous solutions required extensive rework any time a component design changed, he says.
