Orbital drilling has proved to be advantageous to achieve aeronautical-level quality drilling (surface roughness, geometry control…) fully adapted for complex assemblies in a single operation. However, compared to conventional drilling method, this process leads to a drastic change in structure's fatigue life probably due to a non-optimised level of residual stress. The control of the mechanical behaviour of parts obtained by orbital drilling is the goal of the European-CleanSky collaborative R&D project RODEO (Robotized Orbital Drilling Equipment and Optimized Residual Stresses, GA no.738219). In this work, an orbital drilling unit (ORBIBOT) allowing high-speed-machining conditions was developed by PRECISE France, that can be integrated on a lightweight industrial robot. Cutting parameters were determined through an original Tool-Material Couple optimization strategy dedicated to orbital drilling, developed with MITIS Engineering and carried out on aluminium alloy 2024-T351. In order to enhance the mechanical behaviour of the system (fatigue, surface hardening…), an innovative mechanical surface treatment has been introduced for investigations: orbital roller burnishing, performed right after orbital drilling. The burnisher follows a helical path around the hole axis.…
 

Improving competitiveness of Additive Manufacturing Aerospace serial parts

The interest of selective laser melting technology for aerospace parts is very high due to their high complexity and their freedom of design which allow functions integration. However, the competitiveness of Laser Beam Melting (LBM) machines for aerospace industry is limited by two major road blocks. On the one hand, basic parametric set sold with LBM machines are more oriented to historical qualification than productivity rates. For instance, the ongoing qualification on EOS M290 by AIRBUS COMMERCIAL AIRCRAFT only enables us to produce a hundred pieces per machine per year. On the other hand, wasted times between two consecutive manufacturing batches are significant and are impacting the yearly output of the machines. The present project focuses on two activities, focusing on the largest available machines, XLINE2000R and M400, in order to maximize the amount of pieces per build. The first one was the improvement of parametric set productivity, to reduce production time, while keeping material and mechanical properties. We focused on main aerospace materials: titanium alloys, aluminum alloys (Scalmalloy®) and nickel-chromium-based superalloys. The second one…
