Forschungs- und Technologietransfer GmbH (FOTEC), a analysis subsidiary of the College of Utilized Sciences Wiener Neustadt, has developed key applied sciences for the combination of additive manufacturing into industrial course of chains as a part of the worldwide joint venture Advert-Proc-Add II. The main target was on automated post-processing utilizing Hirtisation, the characterization of additively manufactured surfaces, and the event of database programs for course of optimization.
The venture, funded by the Austrian Analysis Promotion Company (FFG), the German Federal Ministry for Financial Affairs and Local weather Motion (BMWK), and the Flanders Company for Innovation & Entrepreneurship (VLAIO), was coordinated by the ecoplus Mechatronics Cluster, FKM, and KU Leuven. Its goal was to make additive-subtractive manufacturing chains economically viable – together with for small and medium-sized enterprises (SMEs). On this context, FOTEC acted as a number one participant within the discipline of Laser Powder Mattress Fusion (PBF-LB/M) in addition to in electrochemical and mechanical post-processing.
A spotlight of FOTEC’s contribution was the additional growth of the Hirtisation know-how—an electrochemically assisted post-processing methodology for assist removing, cleansing, and smoothing of PBF-LB/M parts. Constructing on the outcomes of the previous venture, focused processing methods had been developed for supplies reminiscent of Ti6Al4V and 1.4404 (stainless-steel). By adapting PBF-LB/M course of parameters, machining allowances as little as 180–550 µm may very well be outlined—an vital step towards material-efficient, automated post-processing. On the identical time, floor roughness values of Sa ≤ 5 µm had been achieved, enabling the exact functionalization of AM parts.
As a part of the venture, FOTEC carried out in depth investigations into the floor integrity of additively manufactured parts. The analysis targeted on analyzing how varied PBF course of parameters, construct orientations, and intermediate remedies affect the ultimate floor properties. Particular consideration was given to the interplay with processes reminiscent of shot peening, warmth therapy, and CNC profile grinding. The ensuing floor matrix gives a stable basis for the focused mixture and optimization of additive and subtractive course of steps.
Digital knowledge system for hybrid course of chains
A serious contribution to digital continuity was the event of a cross-process knowledge administration system, applied within the present venture by the Institute of Manufacturing Engineering and Photonic Applied sciences at TU Wien in collaboration with venture companions. In a prototype setup, a hybrid CAM system was provided with multi-sensor real-time knowledge, from which device paths had been routinely generated. By integrating sensor knowledge, materials properties, and geometry info, an clever, adaptive CAM management system was created—marking a milestone within the automation of complicated Additive-Subtractive Manufacturing (ASM) course of chains.
FOTEC’s analysis efforts had been characterised by a powerful utility focus. All through the venture, check specimens and use instances had been produced and analyzed utilizing supplies reminiscent of Ti64, 316L, and AlSi10Mg. Shut collaboration with the 15 industrial companions—together with corporations from the aerospace, tooling, and medical know-how sectors—ensured that the developed processes may very well be instantly transferred to real-world manufacturing situations.
Mechatronics Cluster’s regional innovation position
The ecoplus Mechatronics Cluster focuses its work on three core areas: Superior Manufacturing, Inexperienced Vitality & Mobility, and Local weather-Impartial Manufacturing. Superior Manufacturing bridges the steel and mechanical engineering industries with future-oriented applied sciences reminiscent of digital instruments and new manufacturing strategies. Additive manufacturing performs a very central position, enabling versatile, resource-efficient, and extremely customizable manufacturing. Inexperienced Vitality & Mobility focuses on the combination of electrical automobiles into good power networks, whereas Local weather-Impartial Manufacturing helps corporations in lowering their carbon footprint.
The cluster is a joint initiative of Decrease Austria and Higher Austria, coordinated by ecoplus, the Enterprise Company of Decrease Austria, and Enterprise Higher Austria. The cooperation tasks initiated and supported by the cluster emphasize collaborative studying between corporations and analysis establishments, and the sensible utility of this information inside companies. The final word purpose is to reinforce the competitiveness of taking part corporations. The ecoplus Mechatronics Cluster is co-financed by the European Union via the “Decrease Austrian Innovation Ecosystem” venture.
