Compared to other additive manufacturing processes, it is characterized above all by its high deposition rate and low system costs. Despite many years of experience in the build-up welding process, WA-DED still holds a number of challenges in terms of process stability. This article analyses the interactions in the WA-DED process. To this end, the process was visualized and described with the help of Structured Analysis and Design Technique (SADT). Building on this, a process Failure Mode and Effects Analysis (FMEA) was presented to identify and priorities risks. Finally, the results of the Taguchi tests were analyzed and visualized. The results illustrate the strong interactions between the influencing factors. These have a material-specific effect on the production results. Each new material composition therefore requires a systematic analysis in order to determine quantitative correlations. In future, these can be supported by machine learning approaches.}, language = {en} } @misc{FischerGruegerWoll, author = {Fischer, Tim Sebastian and Gr{\"u}ger, Lennart and Woll, Ralf}, title = {Modellierung von Einfl{\"u}ssen auf das Wire Arc Additive Manufacturing}, series = {Industrie Management 4.0}, journal = {Industrie Management 4.0}, number = {5}, issn = {2364-9208}, doi = {10.30844/IM_23-5_53-57}, pages = {53 -- 57}, abstract = {Das Wire Arc Additive Manufacturing, kurz WAAM, ist ein additives Fertigungsverfahren, welches metallische Bauteile auf Grundlage des Lichtbogenschweißens fertigt. Additive Fertigung ist laut DIN EN ISO/ASTM 52900 ein Prozess, welcher Bauteile aus 3D-Modelldaten schichtweise herstellt. Die grundlegenden Komponenten sind ein Schweißger{\"a}t, welches die ben{\"o}tigte Energie zum Schmelzen des Metalldrahts in den Prozess einbringt sowie eine F{\"u}hrungsmaschine, welche die vorgegebene Geometrie des Bauteils abf{\"a}hrt. Anwendungsbereiche sind Rapid Prototyping und Tooling, Direct Manufacturing und Additive Repair. Die gr{\"o}ßten Vorteile stellen die kosteng{\"u}nstige Anlagentechnik und die hohen Abscheidungsraten dar. Nachteilig am Verfahren sind die mangelnde Prozessstabilit{\"a}t und Wiederholgenauigkeit. Der Beitrag soll dazu dienen, den Fertigungsprozess des WAAM-Verfahrens {\"u}bersichtlich darzustellen, und dabei auf die komplexen Wechselwirkungen eingehen.}, language = {de} }
