This manufacturing technique has the huge benefit that no forming tool is needed. The knowledge about dimensional deviations which occur in the FDM process is necessary for calculating fits and for determining tolerances. A major challenge is the reproducibility of the dimensional accuracy of FDM parts and the reproducibility between different FDM machines. There are many influential factors on the dimensional accuracy in the FDM process for example geometric, material-specific or process-specific factors, which are considered in this paper. The influence of the part position on the build platform of a Stratasys Fortus 400mc is analyzed in terms of the achievable dimensional accuracy. For this purpose, the temperature distribution in the actively heated build chamber is investigated and possible correlations to the dimensional accuracy are identified. The reproducibility of one machine is examined by a multiple production of the test specimens. In addition, a comparison with three other FDM machines from Stratasys is made. Afterwards, the long-term reproducibility of the dimensional accuracy is verified to consider how environmental influences such as maintenance or modification of machine components affect the dimensional accuracy of the FDM process.}}, author = {{Knoop, F. and Lieneke, Tobias and Schöppner, Volker}}, booktitle = {{Rapid Tech - International Trade Show & Conference for Additive Manufacturing}}, pages = {{52--66}}, title = {{{Reproduzierbarkeit der Maßhaltigkeit im Fused Deposition Modeling}}}, doi = {{10.3139/9783446454606.004}}, year = {{2017}}, } @article{34440, abstract = {{In this paper, the influence of surface roughness on the local tribological load with a dry sliding contact is studied. First, three artificial rough surfaces with similar structure but different asperity heights are generated and projected on a smooth ball. After that, a contact pattern is determined between a rough ball and a smooth surface taking into account the elastic only as well as the linear elastic-perfectly plastic material description. On the basis of the calculated contact pressure distribution, the subsurface stresses and a three-dimensional temperature distribution in the sliding contact are calculated. The solutions show that a low surface roughness not necessarily results in low local tribological load of the surface. }}, author = {{Magyar, Balázs and Sauer, Bernd}}, journal = {{Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology}}, number = {{4}}, pages = {{489--502}}, title = {{{Methods for the simulation of the pressure, stress, and temperature distribution in the contact of fractal generated rough surfaces}}}, doi = {{10.1177/1350650115593962}}, volume = {{231}}, year = {{2017}}, } @article{35095, author = {{Kiekbusch, T and Magyar, Balázs}}, issn = {{1436-4921}}, journal = {{Konstruktion}}, number = {{10}}, title = {{{Mehrkörpersimulation als Werkzeug zur Analyse der Wälzlagerdynamik}}}, volume = {{69}}, year = {{2017}}, } @inproceedings{35227, author = {{Kiekbusch, T and Magyar, Balázs and Sauer, B}}, booktitle = {{VDI Berichte 2308}}, isbn = {{978-3-18-092308-6}}, pages = {{103--112}}, publisher = {{VDI Verlag GmbH}}, title = {{{Multi-Ebenen-Simulation zur Berechnung der lokalen Lebensdauer in hochbelasteten Wälzkontakten}}}, year = {{2017}}, } @inproceedings{35222, author = {{Oehler, M and Magyar, Balázs and Sauer, B}}, booktitle = {{VDI-Berichte 2294}}, isbn = {{978-3-18-092294-2}}, pages = {{363--372}}, publisher = {{VDI Verlag GmbH}}, title = {{{A new standardizable calculation method to predict the efficiency of worm gear drives}}}, year = {{2017}}, } @inproceedings{35229, author = {{Thielen, S and Magyar, Balázs and Burkhart, C and Sauer, B}}, location = {{Schweinfurt}}, pages = {{Vortrag 14}}, title = {{{Verträglichkeitsuntersuchungen am tribologischen Ersatzsystem}}}, year = {{2017}}, } @inproceedings{35225, author = {{Magyar, Balázs and Thielen, S and Löwenstein, M and Becker, A and Sauer, B}}, location = {{Beijing}}, title = {{{EHL Simulation of the Timing Chain Drive}}}, volume = {{ID 494908}}, year = {{2017}}, } @inproceedings{35228, author = {{Emrich, S and Burkhart, C and Magyar, Balázs and Kopnarski, M and Sauer, B}}, location = {{Schweinfurt}}, pages = {{Vortrag 15}}, title = {{{Oberflächenanalyse der Tribokontakte von Radialwellendichtsystemen}}}, year = {{2017}}, } @inproceedings{35226, author = {{Thielen, S and Magyar, Balázs and Foko Foko, F and Sauer, B}}, location = {{Beijing}}, title = {{{EHL Simulation of the Radial Shaft Sealing System}}}, volume = {{ID 494903}}, year = {{2017}}, } @misc{22531, abstract = {{Die Erfindung betrifft eine Bremseinrichtung (12) für eine im unbetätigten Zustand eingefallene Bremse (10), wobei die Bremseinrichtung (12) eine Druckplatte (18), eine Gegenplatte (20), eine zum Verpressen einer Bremsscheibe (16) zwischen der Druckplatte (18) und der Gegenplatte (20) auf die Druckplatte (18) wirkende Energiespeichereinrichtung (22) sowie eine Lüftvorrichtung (26) zum Lüften der Bremse (10) aufweist, wobei diese Lüftvorrichtung (26) zum Lüften der Bremse (10) eine der Energiespeichereinrichtung (22) entgegenwirkende Aktoreinrichtung (28) aufweist.
