The principle of the FDM process is the strand wise deposition of molten thermoplastic polymers, by feeding a filament trough a heated nozzle. Due to the strand and layer wise deposition the cooling of the manufactured component is not uniform. This leads to dimensional deviations which may cause the component to be unusable for the desired application. In this paper, a method is described which is based on the shrinkage compensation through the adaption of every single raster line in components manufactured with the FDM process. The shrinkage compensation is based on a model resulting from a DOE which considers the main influencing factors on the shrinkage behavior of raster lines in the FDM process. An in‐house developed software analyzes the component and locally applies the shrinkage compensation with consideration of the boundary conditions, e.g., the position of the raster line in the component and the process parameters. Following, a validation using a simple geometry is conducted to show the effect of the presented adaptive scaling method.}}, author = {{Moritzer, Elmar and Hecker, Felix}}, issn = {{1022-1360}}, journal = {{Macromolecular Symposia}}, keywords = {{Materials Chemistry, Polymers and Plastics, Organic Chemistry, Condensed Matter Physics}}, number = {{1}}, publisher = {{Wiley}}, title = {{{Adaptive Scaling of Components in the Fused Deposition Modeling Process}}}, doi = {{10.1002/masy.202200181}}, volume = {{411}}, year = {{2023}}, } @inproceedings{52801, author = {{Altepeter, Matthias and Wanke, Sven and Schöppner, Volker}}, booktitle = {{INTERNATIONAL CONFERENCE ON HUMANS AND TECHNOLOGY: A HOLISTIC AND SYMBIOTIC APPROACH TO SUSTAINABLE DEVELOPMENT: ICHT 2022}}, issn = {{0094-243X}}, publisher = {{AIP Publishing}}, title = {{{Analysis and modelling of the material degradation of polypropylene on the co-rotating twin-screw extruder}}}, doi = {{10.1063/5.0135824}}, year = {{2023}}, } @inbook{45111, author = {{Roesmann, Daniel and Gräßler, Iris}}, booktitle = {{The Digital Twin of Humans}}, isbn = {{9783031261039}}, pages = {{187–203}}, publisher = {{Springer International Publishing}}, title = {{{Integration of Human Factors for Assembly Systems of the Future}}}, doi = {{10.1007/978-3-031-26104-6_9}}, year = {{2023}}, } @article{48657, author = {{Moritzer, Elmar and Tölle, Lisa and Greb, C. and Haag, M.}}, issn = {{2504-477X}}, journal = {{Journal of Composites Science}}, number = {{7}}, pages = {{267}}, title = {{{Conceptions and Feasibility Study of Fiber Orientation in the Melt as Part of a Completely Circular Recycling Concept for Fiber-Reinforced Thermoplastics}}}, doi = {{10.3390/jcs7070267}}, year = {{2023}}, } @article{48750, author = {{Schöppner, Volker and Altepeter, Matthias and Austermeier, Laura and Wanke, Sven and Meinheit, Philipp}}, journal = {{Polymers 2023}}, number = {{15(9)}}, pages = {{2181}}, title = {{{Polypropylene Degradation on Co-Rotating Twin-Screw Extruders}}}, doi = {{10.3390/polym15092181}}, year = {{2023}}, } @inproceedings{34736, author = {{Schöppner, Volker and Frank, Maximilian}}, location = {{Fukuoka}}, title = {{{Investigation of the Homogenization Performance of Various Faceted Mixers and Optimization with Regard to Mixing as well as Pressure Throughput Behavior}}}, doi = {{10.1063/5.0135825}}, year = {{2023}}, } @inproceedings{29946, author = {{Schall, Christoph Wilhelm Theodor and Schöppner, Volker}}, booktitle = {{PPS36}}, keywords = {{Computing Resources Provided by the Paderborn Center for Parallel Computing}}, title = {{{Design of a test bench for measuring the degradation behavior of plastics during processing}}}, year = {{2023}}, } @article{48742, author = {{Schöppner, Volker and Schall, Christoph Wilhelm Theodor}}, journal = {{Materials}}, number = {{16(17)}}, pages = {{5891}}, title = {{{Material Characterization of Polypropylene and Polystyrene Regarding Molecular Degradation Behavior}}}, doi = {{10.3390/ma16175891}}, year = {{2023}}, } @article{48654, author = {{Moritzer, Elmar and Held, Christian}}, issn = {{0043-2288}}, journal = {{Welding in the World}}, title = {{{Characterization of additively manufactured parts for direct screwing}}}, doi = {{10.1007/s40194-023-01610-7}}, year = {{2023}}, } @inproceedings{46488, abstract = {{AbstractNew trends and technologies in product creation increase complexity, but at the same time create new potentials such as efficiency rise in task processing by Artificial Intelligence.

For online monitoring of self-piercing riveting, envelope curves are often used to define a tolerance zone for the measured setting force. However, the measurement uncertainty is typically not considered and the force curve of a joint can be wrongly rated as non-conform due to measurement errors and noise. In this article, we present a method for dynamical online filtering and uncertainty determination for noisy force curves using two types of Bayesian filters. The methodology is based on a Bayesian probability framework using a priori information for the process curve and sensor noise. To investigate the general feasibility of the method, force measurements with different noise levels are simulated and processed. The conformity is further assessed taking the uncertainty of the filtered signal into account. The results show that the Bayes filter technique is principally able to reduce noise for well-known characteristics of the process curve and sensor noise. Advantages over common filtering techniques, especially for experimental conditions with less known characteristics, are still to be verified. The methodology could be used in future for closed-loop controls to adapt process parameters dynamically. }}, author = {{Butzhammer, Lorenz and Kappe, Fabian and Meschut, Gerson and Hausotte, Tino }}, booktitle = {{Materials Research Proceedings}}, issn = {{2474-395X}}, publisher = {{Materials Research Forum LLC}}, title = {{{Dynamic conformity assessment for joining force monitoring using Bayes filters}}}, doi = {{10.21741/9781644902417-48}}, year = {{2023}}, } @inproceedings{46974, author = {{Gräßler, Iris and Hieb, Michael}}, publisher = {{CIRP }}, title = {{{Creating Synthetic Datasets for Deep Learning used in Machine Vision}}}, year = {{2023}}, } @inproceedings{46219, abstract = {{AbstractTo select design guidelines engineers have to identify relevant from a bewildering amount of design guidelines.

Challenging in the manufacture of multi-material systems especially in view of changing supply chains is the variety of materials and geometries that bring conventional joining processes to their limits. Therefore, new processes are required, which can react versatile to process and disturbance variables. A widely used industrial joining process is semi-tubular self-piercing riveting, which is however a rigid process. To increase the versatility, the two newly established processes multi-range self-piercing riveting and tumbling self-piercing riveting are combined and the capabilities for targeted material flow control are united. Therefore, an innovative two-stage process based on the combination is introduced in this paper. The rivet is set with the multi-range self-piercing riveting process with an overlap of the rivet head and then formed by a tumbling process. Further, a specific adaptation of the tumbling strategy is used to investigate the possibility of reducing cracks in the rivet head. Thereby, different tumbling strategies are used and similar geometric joint formations are achieved to compare the results. }}, author = {{Wituschek, Simon and Kappe, Fabian and Meschut, Gerson and Lechner, Michael}}, booktitle = {{Materials Research Proceedings}}, issn = {{2474-395X}}, publisher = {{Materials Research Forum LLC}}, title = {{{Combination of versatile self-piercing riveting processes}}}, doi = {{10.21741/9781644902417-16}}, year = {{2023}}, } @inbook{52859, author = {{de Camargo e Souza Câmara, Igor and Turhan, Anni-Yasmin}}, booktitle = {{Logics in Artificial Intelligence}}, isbn = {{9783031436185}}, issn = {{0302-9743}}, publisher = {{Springer Nature Switzerland}}, title = {{{Deciding Subsumption in Defeasible $$\mathcal {ELI}_\bot $$ with Typicality Models}}}, doi = {{10.1007/978-3-031-43619-2_36}}, year = {{2023}}, } @article{52861, author = {{Gil, Oliver Fernández and Patrizi, Fabio and Perelli, Giuseppe and Turhan, Anni-Yasmin}}, journal = {{CoRR}}, title = {{{Optimal Alignment of Temporal Knowledge Bases}}}, doi = {{10.48550/ARXIV.2307.15439}}, volume = {{abs/2307.15439}}, year = {{2023}}, }
