Model Based Approach For Energy And Resource Efficient Machining Systems

This book provides a concept to analyze and increase the energy and resource efficiency of machining systems. Machining systems are widely used to produce workpieces in large quantities and with complex geometrical shapes. These systems, however, are also relevant in terms of energy and resource consumption, which is strongly connected to the choice of cutting fluid strategy. Within the focus of the concept, cutting fluid connects the elements of the machining system and results in interactions between them. Based on this description and an extensive literature review, a modeling approach is developed that comprises the relations between process parameters, cutting fluid strategies, and relevant machining system elements. The performance of the machining system is assessed with regard to environmental, economic as well as technological indicators and improved by various organizational and technical measures. The exemplary application of the developed concept is carried out in the context of two case studies and also indicates the corresponding effects of improvement measures.

A comprehensive review to the theory, application and research of machine learning for future wireless communications In one single volume, Machine Learning for Future Wireless Communications provides a comprehensive and highly accessible treatment to the theory, applications and current research developments to the technology aspects related to machine learning for wireless communications and networks. The technology development of machine learning for wireless communications has grown explosively and is one of the biggest trends in related academic, research and industry communities. Deep neural networks-based machine learning technology is a promising tool to attack the big challenge in wireless communications and networks imposed by the increasing demands in terms of capacity, coverage, latency, efficiency flexibility, compatibility, quality of experience and silicon convergence. The author – a noted expert on the topic – covers a wide range of topics including system architecture and optimization, physical-layer and cross-layer processing, air interface and protocol design, beamforming and antenna configuration, network coding and slicing, cell acquisition and handover, scheduling and rate adaption, radio access control, smart proactive caching and adaptive resource allocations. Uniquely organized into three categories: Spectrum Intelligence, Transmission Intelligence and Network Intelligence, this important resource: Offers a comprehensive review of the theory, applications and current developments of machine learning for wireless communications and networks Covers a range of topics from architecture and optimization to adaptive resource allocations Reviews state-of-the-art machine learning based solutions for network coverage Includes an overview of the applications of machine learning algorithms in future wireless networks Explores flexible backhaul and front-haul, cross-layer optimization and coding, full-duplex radio, digital front-end (DFE) and radio-frequency (RF) processing Written for professional engineers, researchers, scientists, manufacturers, network operators, software developers and graduate students, Machine Learning for Future Wireless Communications presents in 21 chapters a comprehensive review of the topic authored by an expert in the field.

Energy efficiency represents a cost-effective and immediate strategy of a sustainable development. Due to substantial environmental and economic implications, a strong emphasis is put on the electrical energy requirements of machine tools for metalworking processes. The improvement of energy efficiency is however confronted with diverse barriers, which sustain an energy efficiency gap of unexploited potential. The deficiencies lie in the lack of information about the actual energy requirements of machine tools, a minimum energy reference to quantify improvement potential and the possible actions to improve the energy demand. Therefore, a comprehensive concept for energy performance management of machine tools is developed which guides the transition towards energy efficient machine tools. It is structured in four innovative concept modules, which are embedded into step-by-step workflow models. The capability of the performance management concept is demonstrated in an automotive manufacturing environment. The target audience primarily comprises researchers and practitioners challenged to enhance energy efficiency in manufacturing. The book may also be beneficial for graduate students who want to specialize in this field.

Over the last several years, manufacturers have expressed increasing interest in reducing their energy consumption and have begun to search for opportunities to reduce their energy usage. In this book, the authors explore a variety of opportunities to reduce the energy footprint of manufacturing. These opportunities cover the entire spatial scale of the manufacturing enterprise: from unit process-oriented approaches to enterprise-level strategies. Each chapter examines some aspect of this spatial scale, and discusses and describes the opportunities that exist at that level. Case studies demonstrate how the opportunity may be acted on with practical guidance on how to respond to these opportunities.

The Green Factories in Bavaria bundle up the research skills of all relevant fields for energy efficient production, e.g. Mechanical Engineering, Processing Technologies, Electrical Engineering, Information Technology, Process Engineering, Materials Science and Economic Science. They also consider all major types of energy, e.g. for motion, illumination, information processing, manufacturing processes and thermal control. Furthermore, Green Factories address the use of energy in production, logistics and administration. With clear focus on energy efficiency in the production and Bavarian-wide, interdisciplinary collaboration, these Green Factories have to be expanded into an international research network. We hope that presented articles from 3rd Green Factory Bavaria Colloquium 2016 will be useful for many researchers and engineers for the development and operation of modern energy-efficient productions.

Metal cutting is a science and technology of great interest for several important industries, such as automotive, aeronautics, aerospace, moulds and dies, biomedicine, etc. Metal cutting is a manufacturing process in which parts are shaped by removal of unwanted material. The interest for this topic increased over the last twenty years, with rapid advances in materials science, automation and control, and computers technology. The present volume aims to provide research developments in metal cutting for modern industry. This volume can be used by students, academics, researchers, and engineering professionals in mechanical, manufacturing, and materials industries. THE SERIES: ADVANCED MECHANICAL ENGINEERING Currently, it is possible to defi ne mechanical engineering as the branch of engineering that “involves the application of principles of physics and engineering for the design, manufacturing, automation and maintenance of mechanical systems”. Mechanical Engineering is closely related to a number of other engineering disciplines. This series fosters information exchange and discussion on all aspects of mechanical engineering with a special emphasis on research and development from a number of perspectives including (but not limited to) materials and manufacturing processes, machining and machine tools, tribology and surface engineering, structural mechanics, applied and computational mechanics, mechanical design, mechatronics and robotics, fluid mechanics and heat transfer, renewable energies, biomechanics, nanoengineering and nanomechanics. In addition, the series covers the full range of sustainability aspects related with mechanical engineering. Advanced Mechanical Engineering is an essential reference for students, academics, researchers, materials, mechanical and manufacturing engineers and professionals in mechanical engineering.
