These topics were presented by Dieter Weise from the Fraunhofer Institute for Machine Tools and Forming Technology IWU and Roman Gabor from the Nanotechnology Centre, part of the Centre for Energy and Environmental Technologies at VSB – Technical University of Ostrava.
The more economical production of customised sheet metal parts in small batches would be welcomed by many industrial companies. Incremental sheet metal forming is a suitable alternative to the conventional approach, which requires, among others, expensive tooling. "Compared to full, milled dies, we can save approximately 80 percent of material. It is also possible to print on existing PLA dies and use this approach to produce derivatives," Weise explained the main advantages of the technology.
This subject was part of the RapidSheet project in which Fraunhofer IWU researchers were involved and which Weise presented at the seminar. "The project was completed at the end of last year. We expect ISF applications to be faster, more flexible and also more cost and resource efficient," he added.
In the second presentation, Roman Gabor focused on micro-arc oxidation technology for surface modification of structural materials and titanium implants. "The main advantage of the application of this technology is the range of applications including surface modification to achieve the required corrosion, tribological and antibacterial properties. The limitations are based on the specific application goals represented by the specific design requirements of the oxide layers and their properties in the environment of application," Gabor said.
Unlike Weise, this was Gabor's first time lecturing at the FIP Academy. He finds the seminars beneficial. "They show an interesting qualitative approach to different scientific disciplines using their own methods of research," Gabor believes.
Researchers from VSB-TUO, the Fraunhofer Institute for Chemical Technology ICT and the Fraunhofer Institute for Machine Tools and Forming Technology IWU are involved in the seminars organised by the FIP Academy. The next seminar will take place on 6 April.
