This monograph focuses on abrasive tools for grinding, polishing, honing, and lapping operations. The book describes the life cycle of abrasive tools from raw material processing of abrasive grits and bonding, manufacturing of monolithic or multi-layered tools, tool use to tool end-of-life. Moreover, this work highlights sustainability challenges including economic, environmental, social and technological aspects. The target audience primarily comprises research and industry experts in the field of manufacturing, but the book may also be beneficial for graduate students.

Serious problems and risks can be observed in European freight transportation development. However, the transport and logistics sector shows a lack of tradition in utilising systematic innovation management to overcome these problems. Hence, this volume puts forward a specific and comprehensive Systemic Migration-Oriented Innovation Management Method. Within the scope of this research, seven case studies of European freight transport innovations have been conducted using this method. They offer a broad, comprehensive and up-to-date view concerning different carriers, degrees of automation, and corridors across Europe. These case studies demonstrate how implementations of innovations may be performed successfully.

New ideas for new products are not enough for creating successful markets: Product Innovation means to manage the whole chain from invention to new and best selling products in market. This innovation roadmap has to be carefully and systematically planned and procured. There are a lot of methods for creativity, market analysis, evaluation, technology forecast, and decision gates available within this book. These methods and tools are brought together and their scopes of application as well as their limitations are shown. The whole tool kit of methods and decision models like market studies, value engineering, TRIZ or portfolio analysis and others are linked together to the overall Aachen Innovation Model (AIM). This handbook is to be used as an innovation management guide as well as an information source for nearly all methods and tools in the field of innovation for technical products. The complete Innovation Road Map is supported by an interactive, multiple user software tool "EDEN" on an ontology basis. Thus the user has not only access to the collected know how of the past, but can also contribute to growth of expertise within his or her enterprise.

DIN norm 8589 subsumes within the group “machining with geometrically - defined cutting edges” the following material removal manufacturing processes: grinding, honing, lapping, free abrasive grinding and abrasive blast cutting.

The Laser world consists basically of two areas, which are necessary and in many cases also sufficient for effective innovation: The right laser for the right application.

Motivation for this Book Ontologies have received increasing attention over the last two decades. Their roots can be traced back to the ancient philosophers, who were interested in a c- ceptualization of the world. In the more recent past, ontologies and ontological engineering have evolved in computer science, building on various roots such as logics, knowledge representation, information modeling and management, and (knowledge-based) information systems. Most recently, largely driven by the next generation internet, the so-called Semantic Web, ontological software engineering has developed into a scientific field of its own, which puts particular emphasis on the theoretical foundations of representation and reasoning, and on the methods and tools required for building ontology-based software applications in diverse domains. Though this field is largely dominated by computer science, close re- tionships have been established with its diverse areas of application, where - searchers are interested in exploiting the results of ontological software engine- ing, particularly to build large knowledge-intensive applications at high productivity and low maintenance effort. Consequently, a large number of scientific papers and monographs have been p- lished in the very recent past dealing with the theory and practice of ontological software engineering. So far, the majority of those books are dedicated to the th- retical foundations of ontologies, including philosophical treatises and their re- tionships to established methods in information systems and ontological software engineering.

Auralization is the creation of audible acoustic sceneries from computer-generated data. The term "auralization" is to be understood as being analogue to the well-known technique of "visualization". In visual illustration of scenes, data or any other meaningful information, in movie animation and in computer graphics, we describe the process of "making visible" as visualization. In acoustics, auralization is taking place when acoustic effects, primary sound signals or means of sound reinforcement or sound transmission, are processed to be presented by using electro-acoustic equipment. This book is organized as comprehensive collection of basics, methodology and strategies of acoustic simulation and auralization. With mathematical background of advanced students the reader will be able to follow the main strategy of auralization easily and work own implementations of auralization in various fields of applications in acoustic engineering, sound design and virtual reality. For readersinterested in basic research the technique of auralization may be useful to create sound stimuli for specific investigations in linguistic, medical, neurological and psychological research and in the field of human-machine interaction.

DIN norm 8589 subsumes within the group “machining with geometrically - defined cutting edges” the following material removal manufacturing processes: grinding, honing, lapping, free abrasive grinding and abrasive blast cutting.

The book series on manufacturing processes for engineers is a reference work for scientific and industrial experts. This volume on Turning, Milling and Drilling starts from the basic principles of machining with geometrically defined cutting edges based on a common active principle. In addition, appropriate tool designs as well as the reasonable use of cutting material are presented. A detailed chapter about the machinability of the most important workpiece materials, such as steel and cast iron, light metal alloys and high temperature resistant materials imparts a broad knowledge of the interrelations between workpiece materials, cutting materials and process parameters.This book is in the RWTHedition Series as are the other four volumes of the reference work.

The book describes the design of micro systems systematically as well as the equations needed for an estimation of the basic elements. It can be used without knowing fabrication processes of micro systems and provides the basic equations needed to calculate the effects and forces which are important in micro systems. For quick reference equations are presented in tables which are found in an index at the end of this book.

This book provides essential information on metal forming, utilizing a practical distinction between bulk and sheet metal forming. In the field of bulk forming, it examines processes of cold, warm and hot bulk forming, as well as rolling and a new addition, the process of thixoforming. As for the field of sheet metal working, on the one hand it deals with sheet metal forming processes (deep drawing, flange forming, stretch drawing, metal spinning and bending). In terms of special processes, the chapters on internal high-pressure forming and high rate forming have been revised and refined. On the other, the book elucidates and presents the state of the art in sheet metal separation processes (shearing and fineblanking). Furthermore, joining by forming has been added to the new edition as a new chapter describing mechanical methods for joining sheet metals.The new chapter “Basic Principles” addresses both sheet metal and bulk forming, in addition to metal physics, plastomechanics and computational basics; these points are complemented by the newly added topics of metallography and analysis, materials and processes for testing, and tribology and lubrication techniques. The chapters are supplemented by an in-depth description of modern numeric methods such as the finite element method. All chapters have been updated and revised for the new edition, and many practical examples from modern manufacturing processes have been added.
