The approach to the solution within the CRC/TR 96 financed by the German Research Foundation DFG aims at measures that will allow manufacturing accuracy to be maintained under thermally unstable conditions with increased productivity, without an additional demand for energy for tempering. The challenge of research in the CRC/TR 96 derives from the attempt to satisfy the conflicting goals of reducing energy consumption and increasing accuracy and productivity in machining. In the current research performed in 19 subprojects within the scope of the CRC/TR 96, correction and compensation solutions that influence the thermo-elastic machine tool behaviour efficiently and are oriented along the thermo-elastic functional chain are explored and implemented. As part of this general objective, the following issues must be researched and engineered in an interdisciplinary setting and brought together into useful overall solutions:   1.  Providing the modelling fundamentals to calculate the heat fluxes and the resulting thermo-elastic deformations in a comprehensive manner, 2.  Mapping of the structural variability as a result of the relative movement inside the machine tool, 3.  Providing the tools for an efficient adjustment of parameters that vary greatly in time and space by means of parameter identification methods as a prerequisite for correction and compensation solutions, 4.  Engineering and demonstrating solutions to control-integrated correction of thermo-elastic errors by an inverse position setpoint compensation of the error at the TCP, 5.  Engineering and demonstrating solutions based on the material properties to compensate for thermo-elastic effects through a homogeneous propagation of the temperature field, as well as reducing and smoothing the distribution of heat dissipated in supporting structures, 6.  Developing metrological fundamentals to record the thermo-elastic errors in special structural areas of machine tools, 7.  Engineering a methodological approach to simultaneous and complex evaluation of the CRC/TR 96 solutions, referring to their impact on product quality, production rate, energy consumption and machine tool costs    

Sharpening workshop tools is probably the most diverse of all workshop activities and the one that is least understood by the majority of workshop owners. This is not unreasonable in view of the wide range of equipment suggested for the task, ranging from the complex, typically an industrial tool and cutter grinder, through to the humble off hand grinder. This book illustrates how most sharpening tasks can be carried out using an off hand grinder and a few simply made accessories, whilst doing this to a standard comparable to that achieved using much more sophisticated equipment. A lack of understanding of the processes almost certainly results in the workshop owner attempting tasks with far from perfect cutting tools that can diminish the satisfaction of a job well done. With the information in this book this situation can be avoided and working with blunt tooling should be a thing of the past.

The elucidation of the effects of structurally extended defects on electronic properties of materials is especially important in view of the current advances in electronic device development that involve defect control and engineering at the nanometer level. This book surveys the properties, effects, roles and characterization of extended defects in semiconductors. The basic properties of extended defects (dislocations, stacking faults, grain boundaries, and precipitates) are outlined, and their effect on the electronic properties of semiconductors, their role in semiconductor devices, and techniques for their characterization are discussed. These topics are among the central issues in the investigation and applications of semiconductors and in the operation of semiconductor devices. The authors preface their treatment with an introduction to semiconductor materials and conclude with a chapter on point defect maldistributions. This text is suitable for advanced undergraduate and graduate students in materials science and engineering, and for those studying semiconductor physics.

Auf dem Gebiet der Ventilatoren ist in jiingster Zeit ein unerwarte- ter Aufschwung eingetreten, der auf die Losung verschiedener stro- mungstechnischer Probleme zuriickzufiihren ist. Die Entwicklung war so rasch, daB plotzlich ein Wirkungsgrad von 90% bei kleiner Bauart er- reieht wurde. Infolgedessen gewann die bis dahin stiefmiitterlich be- handelte Maschinengruppe ganz erheblich an Interesse, was auch durch Dbersetzungen des Buches in mehrere fremde Sprachen zum Ausdruek gekommen ist. Es diirfte nunmehr der geeignete Zeitpunkt sein, das Gesamtgebiet in straffer Form neu darzustellen. Ieh habe vieles umgearbeitet, man- ehes Entbehrliche gestrichen und zahlenmaBige Ergebnisse neuer Ver- suche fUr den Praktiker aufgenommen. Bei Kleinstgeblasen und Quer- stromgeblasen sind wesentliche Erweiterungen erfolgt. Die wichtigen physikalischen GesetzmaBigkeiten wurden ausfiihrlicher gebraeht, die bisherigen Berechnungsverfahren ergiinzt. So erga b sieh eine weit- gehende Neubearbeitung. Mein Manuskript wurde von Prof. Dipl.-Ing. habil. M. PECORNIK (V orstand des Lehrstuhles fUr Stromungslehre und hydraulische Ma- sehinen u. Schiffsbaufalmltat in Rijeka, Universitat Zagreb) sehr ein- gehend durehgesehen. Er hat verschiedene Umstellungen vorgenommen und die Bezeichnungen der vielen Abbildungen systematisch nach den neuesten Vorschriften vereinheitlicht. Dariiber hinaus verdanke ich Prof. PECORNIK viele weitere Ratschlage und Erganzungen sowie seine Hilfe bei der Korrektur, die er mit groBer Umsicht durchfiihrte. Das Kapitel Sehallerzeugung und Schalldampfung wurde wieder von den bekannten Fachleuten Oberingenieur REGENSCHEIT und Dipl.- Ing. GoEHLICH nahezu vollig neu bearbeitet, wofUr ieh ihnen besonders danken mochte.
