Manufacturing Directive Design
The CDF project is IRT SystemX’s first project in the field of additive manufacturing, linked to the inter-IRT FIT Additive Manufacturing programme involving the Jules Verne, M2P, SystemX and Saint Exupéry IRTs.
The CDF project concerns the process of laser metal deposition (LMD) – also referred to as direct energy deposition – which is derived from the hardfacing process developed some thirty years ago. The industrial partners involved in the project are interested in 3D laser deposition by powder spraying because it is particularly suitable for repairing critical parts (for helicopter or aircraft engines, for example). However, there is a lack of simulation and programming tools for the machines capable of making the best use of the process and ensuring wider use in industry. It is on this aspect that IRT SystemX and its partners will be collaborating over a 30-month period.
The CDF project has four main objectives:
- Predict manufacturing times as well as zones of accumulation or lack of material, taking into account machine kinematics.
- Simulate the geometry resulting from the deposition of material as the manufacturing process progresses.
- Detect areas at risk of collision as manufacturing progresses.
- Optimise nozzle paths according to a number of user-defined criteria (manufacturing time, powder or energy savings, material gradient,).
The experimental phase will be carried out on one or more cases from the aviation industry submitted by the industrial partner Safran.
