Thomas Papke, Dominic Bartels, Michael Schmidt, Marion Merklein, Daniel Gerhard, Jonas Baumann, Indra Pitz
Additive Manufacturing has become more important for industrial applications. The technology offers the opportunity of high geometric flexibility and no need of product specific tools including short time to market. The aim is to integrate added value into products by exploiting these possibilities. Therefore, in this work a methodology focusing on these aspects is developed and applied to a structural component.

Additive Manufacturing of Metallic and Ceramic Components

Additive Manufacturing of Metallic and Ceramic Components

Use of Material Extrusion, Especially the Use of Filaments for Sintering Processes
Christian Kukla, Stephan Schuschnigg, Clemens Holzer
The filament printing presented here can be used to produce metallic and ceramic components with complex shapes. Filaments in various highly filled polymers are available for the process. By means of the Shaping-Debinding-Sintering process the green bodies are converted into metallic/ceramic components. As with the PIM process, the filament printing can be used to produce near-net-shape parts, whereby the sintered bodies have a linear shrinkage of 15-20 % compared to the green bodies. In order to produce parts of very high quality, the printing process must be controlled accordingly.

Lithography-based Metal Manufacturing

Lithography-based Metal Manufacturing

New Additive Manufacturing Technology to Produce Small High-precision Metal Components
Andreas Baum, Chiara Armbruster, Carlo Burkhardt
Additive manufacturing (AM) has become one of the biggest trends in modern, industrial ma-nufacturing. The diverse requirements of various industries have led to many different AM processes and process variants. By using AM, advantages such as function integration, lightweight construction or increased efficiency can be enabled. But most of the known AM processes are still facing technological and economic challenges. Especially in applications requiring high accuracy for small parts, production has often been uneconomic until now. Here, the new Lithography-based Metal Manufacturing technology offers new possibilities and opportunities.

Industry 4.0 – The Way to a Digitised Production Company

Industry 4.0 - The Way to a Digitised Production Company

Der Weg zu einem digitalisierten Produktionsunternehmen
Jürgen Köbler, Tobias Fischer, Benjamin Klerch, Michael Schlecht
The age of globalisation is characterised by increased competition. An opportunity to succeed in the face of increasing competition lies in the digitisation of production companies. This article is dedicated to the design of a three-stage model platform of Industry 4.0, which focuses on the consistency of processes from the customer to the supplier at all company levels. The model platform is followed by an overview of the transformation steps for evaluating and shaping progress on the way to become a digitised production company.

Learning with Assistance Systems

Learning with Assistance Systems

Not Seeing the Process for the Tasks?
Gergana Vladova, Philip Wotschack, Patricia de Paiva Lareiro, Norbert Gronau ORCID Icon, Christof Thim
The paper describes the conception and implementation as well as offers an insight into the first results of a study with experimental design in a simulated process environment at the Research and Application Center Industry 4.0 in Potsdam. The focus is on learning processes in the field of simple work and their organization through the use of digital assistance systems. In labour research, there are indications that process knowledge is lost with the use of these systems, in the sense of a good knowledge of the entire work process in which the individual activities are embedded. To investigate the role of process knowledge in the use of digital assistance systems, a real factory situation is simulated in the experiment.

The Digital Control Loop in the Smart Factory

The Digital Control Loop in the Smart Factory

Dennis Schwäke, Axel Hahn, Frank Fürstenau
Production targets in the Smart Factory should be supported by digital control loops. This article will present a concept, which describes the structure of operational information flows as elements of a control loop. The term digital control loop encompasses technical control systems and business processes as well as integrating vertically and horizontally information from business applications. The common alignment of different aspects is adjusted to operational targets along the value added chain. The idea of using the digital control loop as an approach for this, is evaluated in a case study.

The Loop of Cognition

The Loop of Cognition

How “intelligence” is constellated on a silicon basis
Claus Riehle, Thorsten Pötter, Thomas Steckenreiter
In process engineering, one thinks of production operations that are controlled or regulated by sensors and actuators. And any realization of matter transformation is based on a physical substratum, which holds equally for living systems and their behaviour. The article distinguishes between three system levels: the functional level, the interface to the environment and the cognitive level of. Using these three levels, the learning cycle or the previous Cognitive Loop can be very well illustrated. If one compares with this way of distinction the Bio-Informatization of human intelligence with the technical development stages of mechanization, automation, regulation and deep learning, then the cybernetic-sociological term “operational closure” becomes understandable. It becomes obvious that in the context of a digitized culture of production and organization, we should be prepared for a new kind of cognitive loop based on silicon (SI), an intelligent system behavior via ...

What Role Does Real Human-Robot-Collaboration Truly Play in Manufacturing Companies?

What Role Does Real Human-Robot-Collaboration Truly Play in Manufacturing Companies?

Welche Rolle spielt die Mensch-Roboter-Kollaboration in der Praxis?
Tobias Kopp ORCID Icon, Arndt Schäfer, Steffen Kinkel ORCID Icon
Collaborative robots (so-called cobots) that enable secure hand-in-hand collaboration with construction workers without physical separation are regarded as a promising future technology for manufacturing companies. In practice, there are some cases in which people interact with cobots, but very few in which collaboration in a narrower sense takes place. What are the reasons for this lack of collaborative applications? What role does the cobots’ ability to enable collaboration play in practice? The study is based on qualitative evidence gathered in four German small and medium-sized enterprises (SMEs).

Modular Digital Twin for Adaptive Systems

Modular Digital Twin for Adaptive Systems

Human-machine interaction for control of semi-autonomous systems for container unloading
Jasper Wilhelm, Christoph Petzoldt, Thies Beinke, Michael Freitag ORCID Icon
The use of autonomous systems is not efficient in all applications due to variable system environments or small quantities. Semi-autonomous systems are able to bridge this gap. This article presents a digital twin-based approach for human-machine interaction using adaptive automation. A case study shows how a modular digital twin can support the operator of a CPS in specific tasks. This method allows for a distinction between short-term signal changes and long-term behavior modification. Thus, semi-autonomous systems can support operators in scenarios in which autonomous systems are not viable.

Ultrasonic Welding of Biodegradable Plastic Films

Ultrasonic Welding of Biodegradable Plastic Films

Untersuchung biobasierter Kunststoffbeutel für die Handhabung von Trockeneis im TK-Lebensmittelversand
Michael Lütjen ORCID Icon, Jannik Fechner, Michael Freitag ORCID Icon, Maximilian Podein
The food distribution of (deep) refrigerated goods is a steadily growing market segment that deals with sustainability in particular. Due to the high efficiency of the CEP service providers, a shipment as such is not necessarily worse than a shopping trip by car over several kilometers in town. A concrete approach to improve ecological sustainability in food delivery is the substitution of existing PE plastic bags filled with dry ice. The bags help to keep the dry ice together and protect the customer from burns. The following article analyzes ecological aspects of food shipment and conveys an understanding of current development concerning biodegradable plastic films. Due to special material properties of bio-based plastic films, the manufacturability of dry ice bags was investigated in a series of experiments. Dry ice bags were manufactured by means of the very precisely adjustable joining technology ultrasonic welding. Subsequent, load capacity of the dry ice bags was examined.
