In addition, new additive manufacturing processes are constantly being developed, so that a wide range of printing processes are now available for metal. Despite the same starting material, the microstructure and thus also the final mechanical properties differ greatly compared to conventional processes. In most cases, only direction-dependent characteristic values from the uniaxial tension are used to qualify a printing process before it is used. The literature, on the other hand, demonstrates that the results are not transferable to other loading conditions. In this work, several engineering tests were integrated into a single test specimen so that they can be determined on the same specimen. The test specimen can be used to test tooth root strength, bending strength, notched bar impact energy, and thread strength depending on the mounting direction, thus representing industrial loading cases. In this study, test specimens were fabricated by conventional manufacturing (machining), L-PBF (Laser Powder Bed Fusion), and WA-DED (Wire Arc Direct Energy Deposition), and the results were compared using statistical methods. Factors to capture manufacturing influence and buildup direction were statistically validated on 316L. The work shows a benchmark with a typical initial microstructure of rolled and milled material, L-PBF, and WA-DED parts on loads close to the application and thus simplifies an industry-oriented evaluation of a new manufacturing process.}, language = {en} } @incollection{GruegerFischerWoll, author = {Gr{\"u}ger, Lennart and Fischer, Tim Sebastian and Woll, Ralf}, title = {Investigation of the Wire Arc Direct Energy Deposition-Process and Possible Interactions}, series = {Advances in Manufacturing IV}, volume = {2024}, booktitle = {Advances in Manufacturing IV}, editor = {Gapiński, Bartosz and Ciszak, Olaf Stanisław and Ivanov, Vitalii and Machado, Jose Mendes}, edition = {4}, publisher = {Springer Nature Switzerland}, address = {Cham}, isbn = {9783031564659}, issn = {2195-4356}, doi = {10.1007/978-3-031-56463-5_14}, pages = {176 -- 194}, abstract = {The Wire Arc Direct Energy Deposition (WA-DED) process is highly regarded as part of additive manufacturing.

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.

For this reason, companies should compare and adjust the quality standards of all concerning employees with that of the customer, so that the audit criteria can also be reconciled and adjusted accordingly. In this respect, a procedure for matching quality standards has been developed together with a vehicle manufacturer and a feasibility study has been carried out. The focus of the study was on possible differences regarding the detection of defects between the employees, dealers, and customers, as well as the recording and analysis of the visual focus areas. For the study, the participants had to complete a written questionnaire and make a practical defect detection directly on the vehicle. The study results have shown a variety of potentials for action that can be applied at other companies. These include the regular internal matching of the quality standards, the continuous training of the employees as well as the integration of the customers and their changing product requirements after the start of product production.}, language = {en} } @misc{FischerGruegerWoll, author = {Fischer, Tim Sebastian and Gr{\"u}ger, Lennart and Woll, Ralf}, title = {Additive Manufacturing: A Step-by-Step Guide}, series = {Industry 4.0 Science}, journal = {Industry 4.0 Science}, number = {1}, issn = {2942-6162}, doi = {10.30844/I4SE.23.1.80}, pages = {80 -- 88}, abstract = {New technologies have enabled additive manufacturing to construct components layer by layer using 3D model data.

The acquisition of knowledge takes place through facts and statements based on the subject matter and by repetition in exercises. Providing game elements in university teaching, students should be more motivated and deal with the teaching content more intensively. The knowledge imparted is to be prepared more attractively for the students and a greater bond to the respective module is to be built up. Game-typical elements can efficiently link the individual sub-processes of learning with each other and thus maximize a student's performance, knowledge level and motivation. Due to the Covid19 pandemic and the ever-advancing technology development, digital teaching and learning have become essential components of university teaching in the long run. Because quality management is a field that is closely related to practice, the focus is not only on teaching theoretical knowledge but also on practical relevance. The Chair of Quality Management offers the module Project Management every summer semester. The learning objective of the module is to enable students to plan projects and organize their implementation. The module Project Management consists of a lecture, a seminar, and a semester project. In the lecture, students are taught the basics of project management. In the seminar, students learn to select and apply project management methods for different problems. Practical exercises are supported by media and software demonstrations. In the semester project, students get together in groups and plan a project during the semester. The project is intended to help students practically implement the knowledge they have acquired in lectures and seminars. The topics are provided by the chair's corporate partners. To increase the realism of the projects, the handing out of an event card is linked to the interim deadlines. The event card implies an adjustment of already planned resources, activities and/or funds. To optimally adapt the gamification elements for the module, a target group analysis was first conducted as part of the research work. Based on the findings, an action plan was created on how the gamification approach could be transferred into the teaching concept of the module. After implementation, the module was examined further in the course of a teaching evaluation and a survey of the participating students. The main goal of the investigation was to find out to what extent game-typical elements promote the learning process and how practical projects support the learning process. On the one hand, the survey confirmed the promotion of motivation and the learning process by means of game-typical elements among the students. The results show that the creative and diverse way of conveying the learning material is accepted by the students. On the other hand, the study showed that too many of these elements can have a negative effect and a possible saturation effect occurs. Furthermore, the authenticity of the module or the chair may decrease. The results and knowledge from the research work flow into the adjustments of the module and are to be transferred to further modules of the chair in the future.}, language = {en} } @inproceedings{SteinbergWoll, author = {Steinberg, Falk and Woll, Ralf}, title = {Approaches for Handling of difficult to quantify Characteristics in Product Development}, series = {Proceedings of the 15th QMOD Conference on Quality and Service Sciences, Poznan (Poland) 2012}, booktitle = {Proceedings of the 15th QMOD Conference on Quality and Service Sciences, Poznan (Poland) 2012}, publisher = {Univ. of Technology}, address = {Poznan}, isbn = {978-83-89333-46-9}, pages = {1746 -- 1763}, language = {en} } @misc{HaaseWoll, author = {Haase, Florian Vincent and Woll, Ralf}, title = {Zeit ist Trumpf - Schnellere Fehlerkorrektur in der Produktion durch Analyse von Feldausf{\"a}llen}, series = {Qualit{\"a}t und Zuverl{\"a}ssigkeit}, volume = {61}, journal = {Qualit{\"a}t und Zuverl{\"a}ssigkeit}, number = {7}, issn = {0720-1214}, pages = {31 -- 33}, language = {de} } @misc{GoldmannWolterWoll, author = {Goldmann, Christine and Wolter, Anja and Woll, Ralf}, title = {Identifying the challenges of communication within virtual teamwork}, series = {15th International Conference of Education, Research and Innovation, November 7th-9th, 2022, ICERI Proceedings 2022}, journal = {15th International Conference of Education, Research and Innovation, November 7th-9th, 2022, ICERI Proceedings 2022}, publisher = {IATED Academy}, address = {Valencia, Spain}, isbn = {978-84-09-45476-1}, issn = {2340-1095}, doi = {10.21125/iceri.2022.0881}, pages = {3609 -- 3615}, abstract = {In recent years, employees have increasingly been working remotely. Thus, virtual collaboration has continuously gained in importance and the associated change in work organization is realized in virtually collaborating teams. In particular, the communication that takes place under these conditions differs significantly from traditional face-to-face communication and plays a central role in virtual team collaboration. The challenges and opportunities that arise in this context were investigated in this study. The study focuses on identifying the challenges employees face at the communication level in their everyday work. To this end, opinion interviews were conducted with employees of virtually collaborating teams. Based on the identified challenges, a survey was carried out to initiate the analysis based on (quantitative) data collection. After data cleaning, a sample of 291 participants could be collected. From the results obtained, potential improvements for communication, both for the management positions as well as the employees of virtually collaborating teams were derived. The research confirmed that the communication effort in virtual teamwork is higher than in real teamwork. Furthermore, virtual communication has a significant influence on the factors team identification, miscommunication and the decision-making processes in the team. Other findings of the study are that individuals who work only in face-to-face teams are more skeptical of virtual collaboration. In contrast, individuals who work exclusively virtually are more open to virtual and face-to-face collaboration. The results suggest there are more challenges when comparing virtual to face-to-face communication. In addition to the broader findings, it can be seen that the increasingly digitized world of work impacts communication and poses challenges for virtually collaborating teams. In addition to media competence, it is additionally important in this context that individual team members have team- and technology-related skills. In addition to these prerequisites, virtually collaborating team members should be prepared for and continuously supported in virtual collaboration and virtual communication through training, workshops and courses. This can be counteracted by increased communication, soliciting feedback, and face-to-face meetings. The research suggests that transparent and traceable communication and collaboration processes should be implemented in practice.}, language = {en} }
