Iintelligent machine tool

Bild zum Projekt Intelligente Werkzeugmaschine
Contact:reimerifw.uni-hannover.de
Duration:10/2018 - 09.2021
Funded by:DFG
Brief description:Self-stimulated vibrations are the main reason for poor surface quality of the work piece and reduced productivity of machine tools. A high level of expertise is required for setting up a high-productivity process with high process reliability. The development of an "intelligent machine tool", which adapts process parameters such as cutting depth / width, spindle speed and feed rate autonomously to the specific conditions in order to enable a productive and at the same time stable process is the objective of this project. The productivity and working accuracy of machine tools are limited not only by the drive power, but mainly by the dynamic machine properties. Under unfavorable conditions, the static and dynamic forces occurring in the process can lead to chatter vibrations. These self-stimulated vibrations are also noticeable on the work piece surface due to so-called chatter marks. The chatter marks can cause surface tolerances not to be met. The occurrence of chatter vibrations depends on various process variables, such as the depth of cut / and width or the spindle speed. The selection of suitable parameters requires a lot of time for experiments and calculations, expensive measuring equipment and a high level of expert knowledge. The objective of this project is the development and prototypical implementation of an "intelligent machine tool". During the process this machine successively learns at which parameters the process is stable and at the same time as productive as possible. By doing so, the parameters in the process are then adjusted autonomously in such a way that chatter vibrations are avoided, but nevertheless the highest possible material removal is achieved. For this project, the investigations are carried out on the "feeling machine", which uses process-internal sensors to determine the process forces. Methods from the field of artificial intelligence are used for the autonomous adaptation of the process parameters. In this way the feeling machine becomes a learning and intelligent machine in this project.

Principles of a multi-coordinate positioning system for metal cutting machine tools

Bild zum Projekt Grundlagen eines Mehrkoordinatenpositioniersystems für spanende Werkzeugmaschinen
Contact:fuchsfw.uni-hannover.de
Duration:01/15 - 06/17
Funded by:DFG
Brief description:Nowadays, machine tool feed drives are mostly systems with one degree of freedom (dof). By combining multiple systems, movements in multiple dof become relizable. However, this leads to a reduction in dynamics and accuracy of the system. With a multi-dof feed drive system significant benefits can be achieved. The scope of this project is to investigate a system, consisting of a planar direct drive combined with a contactless electromagnetic planar guide. Firstly, a test rig will be designed, realized and tested. Then the feed drive system will be extensively analyzed in terms of accuracy, dynamics and structural behavior. In a second period it is pursued to investigate the system in cutting processes.

Contact:blechifw.uni-hannover.de
Duration:03/18 - 02/20

Brief description:Different load histories of train wheels lead to high variance of material properties on the running surface. Thus, it is difficult to determine general machining parameters for reprocessing and to implement a robust process monitoring system. An online measurement of material properties by means of the Barkhausen effect is applied to allow the definition of individual machining parameters for each sample. In addition, the acoustic emission of the cutting tool is measured and evaluated in conjunction with the material properties to improve the process control.

Brief description:Additive manufacturing (AM) offers high potential in the area of resource-efficient production of components with complex geometries, especially for expensive materials and small batch sizes. However, there are a number of challenges to these advantages. For example, the achievable dimensional accuracy and surface quality is generally not sufficient, so that machining of the components is necessary. Due to the different planning processes and technological boundary conditions in additive or machining production, there is currently only insufficient compatibility of the planning data and there is no continuous development chain. The BMBF-funded joint project PR0F1T aims to develop solutions for these challenges.

Contact:wichmannifw.uni-hannover.de
Duration:01.01.2017-31.12.2018
Funded by:DFG
Brief description:An important quality criterion in the process design is the prevention of geometric shape deviations due to interactions of process and workpiece. The deformation of the workpiece is primarily determined by the process forces, the material properties and the changing workpiece shape over time. Due to these relationships, a large number of experiments is required for the design of tool grinding processes until the process is customised. The aim of this project is the development and research of a method for the model-based design of individual tool grinding processes in industrial environments.

Duration:01.01.2017-31.12.2018
Funded by:DFG
Brief description:Kompetenzen der Mitarbeitenden rücken für Unternehmen in Zeiten der Digitalisierung und des Fachkräftemangels deutlich stärker in den Fokus. Personal, das für aktuelle und zukünftige Unternehmensherausforderungen passend qualifiziert ist, trägt wesentlich zum Unternehmenserfolg bei. Wenn benötigtes Know How jedoch nicht über Neueinstellungen ins Unternehmen geholt werden kann, werden Weiterbildungen genutzt, um die bestehenden Arbeitskräfte entsprechend zu qualifizieren. Eine Wirtschaftlichkeitsbetrachtung der Weiterbildungen ist für die Unternehmen allerdings nicht durchführbar, da lediglich die Kosten, nicht aber der Nutzen der Weiterbildungen bekannt sind. Für eine Gegenüberstellung in einer Kosten-Nutzen-Analyse muss der Effekt der Weiterbildung monetär messbar gemacht werden. Im Forschungsprojekt SAPA wird eine simulationsbasierte Kosten-Nutzen-Betrachtung von Weiterbildungsmaßnahmen angestrebt, die zu einer optimalen Weiterbildungsstrategie für Unternehmen führen soll. Das Forschungsvorhaben wird gemeinsam mit dem Institut für Berufspädagogik und Erwachsenenbildung (ifBE) durchgeführt.

Contact:stobrawaifw.uni-hannover.de
Duration:01.04.2016 - 31.03.2018
Funded by:DFG
Brief description:Die Personalplanung hat das Ziel, die Wettbewerbsfähigkeit eines Unternehmens durch die anforderungsgerechte Qualifizierung der Mitarbeiter langfristig zu sichern. Die Fertigungsplanung greift hingegen kurzfristig auf die gegebenen Ressourcen zurück, um unter anderem Fertigungskosten und -zeiten zu reduzieren und die Qualität zu steigern. Die getrennte Betrachtung auf Unternehmens- bzw. Fertigungsebene führt in der Folge oftmals zu einem Spannungsfeld zwischen der langfristig ausgerichteten Personalentwicklung und dem kurzfristigen Streben nach Produktivitätssteigerungen in der Fertigung. Das Ziel des Projekts ist die Überführung der bisher erarbeiteten Erkenntnisse zum integrierten technologie- und kompetenzorientierten Planungsansatz in ein industrielles Anwendungsszenario. Dazu ist es erforderlich, den bisherigen Planungsansatz um die Berücksichtigung von Methoden-, Sozial- und Selbstkompetenzen, Formen der Gruppenarbeit und Weiterbildungsmaßnahmen zu einer kompetenzorientierten Fertigungs- und Personalplanungsmethodik zu erweitern. Des Weiteren ist die Integration dieser Fertigungs- und Personalplanungsmethodik in ein MES zur industriellen Anwendung in KMU angestrebt.

Die Steuerung von Produktionskapazitäten soll in Abhängigkeit der prognostizierten Nachfrage über eine dynamische Anpassung von Angebotspreisen automatisiert erfolgen. Das Assistenzsystem soll durch ein Add-In eines bestehenden ERP/MES Programms prototypisch umgesetzt werden.
