This open access book compiles the groundbreaking research conducted by the Collaborative Research Center (CRC) 871, centered around the "Regeneration of Complex Capital Goods."

This open access book compiles the groundbreaking research conducted by the Collaborative Research Center (CRC) 871, centered around the "Regeneration of Complex Capital Goods." This comprehensive work unveils an array of innovative methods developed through CRC 871, designed to revitalize and enhance the functional attributes of these critical assets. From non-destructive characterization of heavily stressed turbine components to the dynamic behavior of regenerated structural elements, each chapter offers a meticulous exploration of diverse facets in the field. The book also addresses the crucial consideration of variability in repair processes and material properties, as well as the comprehensive control of regeneration processes. With insights into simulation-based process design, fast measurement techniques, and resilience-based decision criteria, this volume provides a comprehensive view of the cutting-edge approaches employed. Moreover, readers will find a detailed process chain for condition-based regeneration, offering a practical framework for implementation. Finally, the book sheds light on the importance of targeted public relations in disseminating the invaluable research carried out by Collaborative Research Center 871. This extensive compilation not only showcases the scientific rigor behind maintaining complex capital goods but also demonstrates the collaborative efforts that brought together experts from various fields to push the boundaries of regeneration technology.

This contributed volume contains the research results presented at the 4th Machining Innovations Conference, Hannover, September 2013. The topic of the conference are new production technologies in aerospace industry and the focus is on energy efficient machine tools as well as sustainable process planning. The target audience primarily comprises researchers and experts in the field but the book may also be beneficial for graduate students.

The fuel consumption of a modern combustion engine is one of the most important purchase criteria in contemporary society. Increasing oil prices and exhaust emissions taxes force the automotive industry to continuously improve the vehicle engines. The fuel consumption is closely related to the frictional losses of an engine. New material pairings or constructive modifications of the piston group can reduce such losses. Another innovative concept to lower the frictional forces is the micro-structuring of thermo-mechanically highly stressed surfaces. Within an interdisciplinary research group sponsored by the German Research Foundation, scientists at the Leibniz Universität Hannover and Universität Kassel have been working together to investigate this research topic. This final report presents their findings and offers scope for further discussion.

Das in dritter Auflage erscheinende Buch beschreibt die physikalischen Grundlagen des Spanens nach neusten Erkenntnissen der Forschung. Damit verknüpft werden wichtige Bereiche der dadurch möglichen Anwendungen, wie Hochgeschwindigkeitsspanen, Hochleistungsspanen, Trockenbearbeitung und Hartbearbeitung (Hartdrehen und -fräsen), vorgestellt. Die Möglichkeiten der Modellierung und Simulation von spanenden Prozessen werden komprimiert erläutert. Das Werk vermittelt die Anforderungen, die an moderne Werkzeugmaschinen und Werkzeuge sowie an innovative Planungen spanender Prozesse gestellt werden müssen. Des Weiteren werden wichtige Phänomene der Randzonenphysik feinbearbeiteter Bauteile erklärt.

Innovationskraft und Hightech-Produkte machen Deutschland zu einer der führenden Industrienationen. Die Entwicklung neuer und verbesserter Produkte wird auch zukünftig eine herausragende Rolle spielen, denn Produktentwicklung und -gestaltung tragen zu Wohlstand, Wirtschaftswachstum und zur internationalen Wettbewerbsfähigkeit Deutschlands bei. Dabei steckt hinter jedem neuen oder an Kundenwünsche angepassten Produkt eine Meisterleistung: Technische Herausforderungen und Bedarfe müssen erkannt werden. Es müssen geeignete technische Lösungen gefunden werden, die dann in ein funktionierendes und industriell herstellbares Produkt weiter entwickelt werden. Kein Entwicklungsprojekt ist wie das andere und mit jedem wird Neuland betreten. Diese abwechslungsreichen, sich gleichzeitig stetig wandelnden, aber verantwortungsvollen Aufgaben werden im Maschinenbau und in der Elektrotechnikindustrie vielfach von Konstrukteuren übernommen. Die Ausbildung von Konstrukteuren steht damit vor großen Herausforderungen: Sie muss dem Wandel der Tätigkeitsfelder und Anforderungen mit angepassten Ausbildungskonzepten begegnen, auf den Umgang mit der stetigen Weiterentwicklung vorbereiten und gleichzeitig attraktiv sein für den potenziellen Konstrukteurnachwuchs. Vor diesem Hintergrund rief acatech das Projekt „Konstrukteur 2020“ ins Leben. Ziel war es, Lösungsansätze für eine Verbesserung des Berufsimages zu entwickeln sowie Vorschläge für eine zeitgemäße, zukunftsweisende Hochschulausbildung und Weiterbildung von Konstrukteuren zu erarbeiten, die den Erwartungen der Industrie Rechnung tragen. Die vorliegende acatech STUDIE dokumentiert die Detailergebnisse der empirischen Untersuchungen und Workshops dieses Projekts.

This contributed volume collects the scientific results of the DFG Priority Program 1180 Prediction and Manipulation of the Interactions between Structures and Processes. The research program has been conducted during the years 2005 and 2011, whereas the primary goal was the analysis of the interactions between processes and structures in modern production facilities. This book presents the findings of the 20 interdisciplinary subprojects, focusing on different manufacturing processes such as high performance milling, tool grinding or metal forming. It contains experimental investigations as well as mathematical modeling of production processes and machine interactions. New experimental advancements and novel simulation approaches are also included.

Manufacturing is the basic industrial activity generating real value. Cutting and abrasive technologies are the backbone of precision production in machine, automotive and aircraft building as well as of production of consumer goods. We present the knowledge of modern manufacturing in these technologies on the basis of scientific research. The theory of cutting and abrasive processes and the knowledge about their application in industrial practice are a prerequisite for the studies of manufacturing science and an important part of the curriculum of the master study in German mechanical engineering. The basis of this book is our lecture “Basics of cutting and abrasive processes” (4 semester hours/3 credit hours) at the Leibniz University Hannover, which we offer to the diploma and master students specializing in manufacturing science.
