This results in significant advantages over conventional manufacturing methodologies, such as the production of topologically optimized, complex structures, lower material consumption or shorter product development cycles. In order to be able to use these advantages, the possibilities and restrictions of the processes must be known. In particular, selective laser beam melting (SLM), in which a powdery metallic starting material is melted by means of a laser, requires a sound understanding of the process. For this purpose, design guidelines have been presented in various scientific papers. These design guidelines help to design a component in such a way that it can be manufactured successfully using additive manufacturing. These so-called “AMsuitable design guidelines” can be found among others at Adam, Kranz and Thomas [2,3,4,5]. In contrast to established manufacturing processes, the post-processing of additive components is divided into two steps. First, the AM immanent post processing, such as the removing of the component from the building platform or the removing of the remaining powder. These post-processing steps are in the following referred to “post-processing”. Secondly, the subsequent post-processing steps to improve the component properties, such as milling and turning or a stress-relief annealing. These are referred to as “finishing” and form the focus of this paper. With regard to a successful finishing of additively manufactured components, design guidelines must be taken into account that consider the finishing inherent restrictions and possibilities. In the following, these design guidelines are referred to “finishing suitable”. They can deviate significantly from those of conventionally manufactured components in the case of additively manufactured components. Although there are some investigations that deal with the post-processing of additively manufactured components [6,7], there are hardly any design guidelines that are suitable for finishing [8]. Therefore, knowledge about the finishing of additively manufactured components is based on experimental experience rather than on scientific knowledge. For this reason, design guidelines for a finishing suitable design must be methodically determined and quantified. These quantified design guidelines can be used for an automated design check on complex components like topology optimized geometries.}}, author = {{Lammers, Stefan and Tominski, Johannes and Zimmer, Detmar}}, booktitle = {{II International Conference on Simulation for Additive Manufacturing Sim-AM 2019 11-13 September, 2019}}, isbn = {{978-84-949194-8-0}}, pages = {{174--185}}, title = {{{Guidelines for post processing oriented design of additive manufactured parts for use in topology optimization}}}, doi = {{http://congress.cimne.com/sim-am2019/frontal/doc/EbookSim-AM2019.pdf}}, year = {{2019}}, } @inproceedings{25641, abstract = {{Langzeitfestigkeit von Schweißungen aus PP unter Berücksichtigung der Morphologie}}, author = {{Schöppner, Volker and Wübbeke, Andrea and Paul, Andre and Tiemann, Michael and Fitze, F. and Austermeier, Laura and Chen, M. and Jakob, F. and Heim, H.-P. and Wu, T. and Niendorf, T. and Röhricht, M-L. and Schmidt, M.}}, booktitle = {{Werkstoffwoche (2019)}}, location = {{Dresden (Deutschland)}}, title = {{{Langzeitfestigkeit von Schweißungen aus PP unter Berücksichtigung der Morphologie}}}, year = {{2019}}, } @inproceedings{15068, author = {{Wiens, Eugen and Homberg, Werner}}, booktitle = {{PROCEEDINGS OF THE 22ND INTERNATIONAL ESAFORM CONFERENCE ON MATERIAL FORMING: ESAFORM 2019}}, title = {{{Forming analysis of tailored tubes with an internal contoured wall thickness and external axial ribs manufactured by internal flow-turning}}}, doi = {{10.1063/1.5112535}}, year = {{2019}}, } @inproceedings{16027, author = {{Camberg, Alan Adam and Striewe, Marius and Tröster, Thomas and Bohner, F. and Tölle, J.}}, booktitle = {{5th MATFEM Conference}}, location = {{Schloss Hohenkammer}}, publisher = {{MATFEM}}, title = {{{Investigation of ductility and fracture behavior of EN AW-5182 H18 at non-isothermal forming conditions}}}, year = {{2019}}, } @book{16795, author = {{Striewe, Jan André and Tröster, Thomas and Kowatz, Jannik and Meschut, Gerson and Grothe, Richard and Grundmeier, Guido}}, publisher = {{Europäische Forschungsgesellschaft für Blechverarbeitung}}, title = {{{Analyse und Optimierung des Korrosions- und Alterungsverhaltens von hybriden Strukturen aus Metallen und CFK}}}, year = {{2019}}, } @inproceedings{16028, author = {{Grothe, R. and Striewe, Jan André and Kowatz, Jannik and Grundmeier, Guido and Tröster, Thomas and Meschut, Gerson}}, location = {{Bad Boll }}, title = {{{Analyse und Optimierung des Korrosions- und Alterungsverhaltens von hybriden Strukturen aus Metallen und CFK}}}, year = {{2019}}, } @article{23907, abstract = {{One of the strategies employed to lower weight and to decrease material consumption is reducing part thickness itself. Thus, functionally graded materials in which structural reinforcement is adjusted locally, are of great interest. With regard to conventional industrial processes, such as extrusion or flexible cold rolling, thickness variations can only be achieved either longitudinally or through the cross-section of the semi-finished products. Hence, a combined thickness variation (along both axes) is difficult to generate solely by extrusion or rolling. A simultaneous thickness variation in both directions, however, would enable further weight savings in structural components such as car body parts. In this study, a promising approach with extruded shapes, serving as a billet for a flexible hot rolling process, is elaborated upon. By employing the described process modification, shapes with simultaneous thickness variations in longitudinal as well as in transverse direction are feasible. Initial numerical analysis reveals the weight-saving potential of using these semi-finished products for structural parts in a car body. A demonstration of the production process for the semi-finished parts and the occurring challenges are discussed. To verify and adjust the new technology, a numerical model of the flexible hot rolling process has been created based on the finite element software QForm VX. This model is also employed for tool design optimization to produce semi-finished components with the required geometrical quality. Finally, the results of hot rolling experiments conducted using the adjusted roll design are presented.}}, author = {{Grydin, Olexandr and Sotirov, Nikolay and Samsonenko, Andrii and Biba, Nikolay and Andreiev, Anatolii and Stolbchenko, Mykhailo and Behr, Teresa and Frolov, Iaroslav and Schaper, Mirko}}, issn = {{1662-9752}}, journal = {{Materials Science Forum}}, pages = {{85--92}}, title = {{{Flexible Hot Rolling of Extruded Shapes of Aluminum Alloy EN AW-6082}}}, doi = {{10.4028/www.scientific.net/msf.949.85}}, year = {{2019}}, }
