Delcam has partnered with Cranfield University, Airbus Group and the University of Bath in a major project looking at the use of Additive Layer Manufacturing (ALM, more commonly known as 3-D printing) to revolutionise the production of titanium alloy aircraft components.
The £995,000 project, which began at the Cranfield University Welding Engineering and Laser Processing Centre in January 2014, is looking at the industrial potential of RAWFEED, Rolling Assisted Wire Feed Direct Deposition for Production of High Value Aerospace Components. The ALM process would reduce waste in the manufacture of titanium components from the current 80-90% to 30-35%, and increase production speed 50-fold compared to components manufactured using conventional methods.
Step by step
The RAWFEED process uses a welding torch to deposit a continuous bead of material on a titanium baseplate, creating the first layer of the component. The layer is allowed to cool and is then rolled to enhance the material’s properties. This process is repeated until the required 3D shape is completed. Managed by Airbus and supported by £630,000 support from the UK Technology Strategy Board, the research is looking to validate a cost model and define the machine architecture and specification to exploit the industrial potential of this emerging technology.
Delcam is providing the high quality control software for the project over a wide range of machine tool and robotic platforms. The University of Bath’s Laboratory for Integrated Metrology Applications (LIMA) will develop a measuring system that will help control and quality assure the process. Curtis Carson, Head of Systems Integration – Manufacturing Engineering at Airbus Group commented: “Airbus currently procures £250m of these components every year, so the savings in terms of waste and production efficiency are enormous. We are proud to be associated with this cutting edge technology project, which is a continuation of the work to date on additive layer manufacturing, and confirms its potential for industrial scale application. RAWFEED could dramatically transform the way high-value aerospace components are manufactured, as part of lean and efficient UK industry of the future. We, and our partners, are very grateful for the support of the Technology Strategy Board, which is continuing to join us in investing in innovation in the UK aerospace industry.”
