A team of researchers at the Fraunhofer Institute for Production Technology IPT in Aachen has developed a hybrid additive manufacturing process that combines wire-based and powder-based laser cladding (LMD). The new process can be used to apply protective coatings of high-strength tool steel to workpieces and repair surface defects at low cost. The tool coatings produced in this way are more wear-resistant, resource-efficient and cost-efficient than those produced by other methods. Following successful test series with tool components, there are plans to use the process to machine hydraulic components.

Manufacturing companies that network their machines and systems are particularly at risk from security vulnerabilities and attacks on their IT infrastructure. This was determined by the Fraunhofer Institute for Production Technology IPT in the course of scientific investigations for the white paper "Cybersecurity in Networked Production", which has now also been published in English. The Aachen scientists now want to further develop the cross-industry "Production Security Readiness Check" in an AiF-funded research project together with small and medium-sized enterprises (SMEs). Interested companies that would like to thoroughly check their production IT with regard to protection and security can still participate in the project.

To create a sustainable road traffic system, hundreds of thousands of fuel cells will be needed for hydrogen-powered cars in the future. Until now, though, fuel cell production has been complex and too slow. The Fraunhofer team is therefore developing a continuous production line that will be able to process fuel cell components in cycles lasting just seconds. The pilot line is set to be presented at the Hannover Messe Digital Edition from April 12 to April 16, 2021.

Industrial production today is only about one thing: productivity. Until now, the values behind this term have prevented a zero-emission and sustainable production, even though it would already be technologically and economically possible. However, changing requirements of the capital market from a plain financial orientation to a holistic view of sustainability, demand that German companies rethink the concept of productivity. The Laboratory for Machine Tools and Production Engineering (WZL) of RWTH Aachen University and the Fraunhofer Institute for Production Technology IPT will discuss the question of how the Internet of Production (IoP) can support this process and at the same time make companies crisis-proof during the 30th Aachen Machine Tool Colloquium (AWK) on September 22 and 23, 2021, at Eurogress Aachen and in digital form.

Being able to reliably and safely control and regulate highly dynamic production systems still appears to be a challenge for many companies. Edge and cloud systems are gaining in importance, but even today there is still a lack of appropriate equipment and infrastructure to permanently integrate existing machines and plants into digital IT landscapes in accordance with the necessary industrial requirements. To this end, the Fraunhofer Institute for Production Technology IPT in Aachen, together with partners from mechanical engineering, network technology and robotics, is now developing an end-to-end real-time-capable communication infrastructure based on 5G mobile technology and the Time Sensitive Networking (TSN).

The treatment of cancer with new, individualized cell therapies is usually very costly and lengthy. Before treatment can take place, patients often have to wait a long time for individualized therapeutics to be produced and they lose valuable time. In the EU project AIDPATH, researchers are now developing a facility for the production of so-called CAR-T cells that is capable of integrating patient-related data and biomarkers into the therapy process via artificial intelligence. The CAR-T cells are produced close to the patient, directly in the hospital. In the future, this will make it possible to provide cancer patients with treatment tailored to their needs and much more quickly.

Complex production processes in highly flexible and networked manufacturing systems require all processes and distributed systems to be able to exchange their data extremely reliably and with only short delay times. For this so-called "Ultra Reliable and Low Latency Communication" (URLLC), the 3rd Generation Partnership Project (3GPP), a worldwide cooperation for the standardization of mobile communication technologies, is developing a new standard for future 5G products. The Fraunhofer-Institute for Production Technology IPT and the Swedish mobile communications supplier Ericsson are now testing the envisaged URLLC functions in Aachen using a real production scenario for collision control in machine tools.

Even in the “Corona Year” the international toolmaking industry does not give in and proves to be resilient to the crisis: Harting Applied Technologies GmbH from Espelkamp in Westphalia, Germany, won the “Excellence in Production” award this year and is thus awarded the title “Toolmaker of the Year 2020”.

Big Data solutions require densely integrated networks of production facilities and IT – which, in turn, oblige companies to invest heavily in resources and technological skills. This is why the Fraunhofer Institute for Production Technology IPT and its project partner German Edge Cloud are currently developing an open test environment for research and industry in Aachen that will allow the testing of digitalization concepts in actual production facilities with a view to integrating these concepts into industrial production lines.

As transmitters of power and torque, shafts are inconspicuous yet irreplaceable components of cars, aircraft, ships or wind turbines. Billions of these components are produced worldwide every year in various sizes, most of them with shoulders or other surface features. A team from the Fraunhofer Institute for Production Technology IPT has now developed the additive process »Express Wire Coil Cladding« (short, EW2C) for the surface treatment of shafts. The EW2C process is an alternative to common ablative processes of shaft machining such as turning, an alternative that not only conserves resources, but also lowers costs.
