Modern Grinding Technology And Systems

This specialist edition features key innovations in the science and engineering of new grinding processes, abrasives, tools, machines, and systems for a range of important industrial applications. Topics written by invited, internationally recognized authors review the advances and present results of research over a range of well-known grinding processes. A significant introductory review chapter explores innovations to achieve high productivity and very high precision in grinding. The reviewed applications range from grinding systems for very large lenses and reflectors, through to medium size grinding machine processes, and down to grinding very small components used in MEMS . Early research chapters explore the influence of grinding wheel topography on surface integrity and wheel wear. A novel chapter on abrasive processes also addresses the finishing of parts produced by additive manufacturing through mass finishing. Materials to be ground range from conventional engineering steels to aerospace materials, ceramics, and composites. The research findings highlight important new results for avoiding material sub-surface damage. The papers compiled in this book include references to many source publications which will be found invaluable for further research, such as new features introduced into control systems to improve process efficiency. The papers also reflect significant improvements and research findings relating to many aspects of grinding processes, including machines, materials, abrasives, wheel preparation, coolants, lubricants, and fluid delivery. Finally, a definitive chapter summarizes the optimal settings for high precision and the achievement of centerless grinding stability.

The latest information indicates that the United States now spends in excess of $150 billion annually to perform its metal removal tasks using conventional machining technology. That estimate is increased from $115 billion 5 years ago. It becomes clear that metal removal technology is a very important candidate for rigorous investigation looking toward improvement of productivity within the manufacturing system. To aid in that endeavor, an extensive program of research has developed within the industrial community with the express purpose of establishing a new scientific and applied base that will provide principles upon which new manufacturing decisions can be made. One of the metal removal techniques that has the potential for great economic advantages is high-rate metal removal with related technologies. This text is concerned with the field of grinding as a subset of the general field of high-rate metal removal. Related processes (not covered in this text) include such topics as turning, drilling, and milling. In the final evaluation, the correct decision in the determination of a grinding process must necessarily include an understanding of the other methods of metal removal. The term grinding, as used herein, includes polishing, buffing, lapping, and honing as well as conventional definition: "... removing either metallic or other materials by the use of a solid grinding wheel".

The book is aimed at practitioners, engineers, researchers, students and teachers. The approach is direct, concise and authoritative. Progressing through each major element of the grinding system and then on to machine developments and process control, the reader becomes aware of all aspects of operation and design. Trends are described demonstrating key features. Coverage includes abrasives and super-abrasives, wheel design, dressing technology, machine accuracy and productivity, grinding machine design, high-speed grinding technology, cost optimization, ultra-precision grinding, process control developments, vibration control, coolants and fluid delivery. Trends in high precision and high speed grinding are explored Principles underlying improvements in machines and processes are explained Numerically worked examples give scale to essential process parameters Recent research findings and original contributions to knowledge are included A number of ultra-precision grinding machine developments are included

Principles of Modern Grinding Technology, Second Edition, provides insights into modern grinding technology based on the author’s 40 years of research and experience in the field. It provides a concise treatment of the principles involved and shows how grinding precision and quality of results can be improved and costs reduced. Every aspect of the grinding process--techniques, machines and machine design, process control, and productivity optimization aspects--come under the searchlight. The new edition is an extensive revision and expansion of the first edition covering all the latest developments, including center-less grinding and ultra-precision grinding. Analyses of factors that influence grinding behavior are provided and applications are presented assisted by numerical examples for illustration. The new edition of this well-proven reference is an indispensible source for technicians, engineers, researchers, teachers, and students who are involved with grinding processes. Well-proven source revised and expanded by undisputed authority in the field of grinding processes Coverage of the latest developments, such as ultra-precision grinding machine developments and trends in high-speed grinding Numerically worked examples give scale to essential process parameters The book as a whole and in particular the treatment of center-less grinding is considered to be unchallenged by other books

Concrete Technology: Theory and Practice" gives students of Civil Engineering a thorough understanding of all aspects of concrete technology from first principles. It covers types of Cement, Admixtures, Concrete strength, durability and testing with reference to national standards.

The urgent need to keep pace with the accelerating globalization of manufacturing in the 21st century has produced rapid advances in manufacturing research, development and innovation. This book presents the proceedings of the 15th International Conference on Manufacturing Research (ICMR 2017), which also incorporated the 32nd National Conference on Manufacturing Research (NCMR) and was held at the University of Greenwich, London, UK, in September 2017. The conference brings together a broad community of researchers who share the common goal of developing and managing the technologies and operations key to sustaining the success of manufacturing businesses. The book is divided into 13 parts, covering topics such as advanced manufacturing technologies (including additive, ultra-precision and nano-manufacturing); manufacturing systems (digital and cyber-physical systems); product design and development (including lifecycle management and supply-chain collaboration); information and communication (including innovation and knowledge management); and manufacturing management (including lean, sustainable and cost engineering). With its comprehensive overview of current developments, this book will be of interest to all those involved in manufacturing today.
