Project Timeline
Start: January 1, 2019 – End: December 31, 2021
Budget: €2.0 million
Coordinator: Fraunhofer IPA (Andreas Gebhardt)
Partners: ARRTSM, BMW, Dynamic Robotic Solutions (DE/USA), Fraunhofer IPA, Hochschule Augsburg, Hufschmied, IACMI (USA), Michigan State University, SGL Carbon, TRUMPF, University of Augsburg, Voith HySTech, technotrans AG, Reichenbacher, and others
Motivation & Background
Mass production of CFRP components is hampered by edge resin overflow, waste trim, and process inefficiencies. The MAI iSPAN consortium aimed to address these challenges through advanced trimming techniques—laser, waterjet, and dry machining—applied to near-net-shape carbon-fiber composites.
Key Technical Breakthroughs
Dry CNC trimming: Minimized coolant use, with novel tool-paths to reduce waste and emissions.
These techniques collectively improved surface quality, reduced scrap, and lowered environmental footprint.
Strategic Impact for ARRTSM
Robotics Integration: Trim process aligns with ARRTSM’s autonomous fabrication systems.
Cost & Sustainability: Lower scrap and less coolant foot-print boost cost-efficiency and eco-credentials.
Industry Reach: Collaborating with leaders like BMW and Fraunhofer reinforces ARRTSM’s premium engineering network.
