Book Description
Having edited "Journal of Materials Processing Technology" (previously entitled "Journal of Mechanical Working Technology") for close on 25 years, I have seen the many dramatic changes that have occurred in the materials processing field. Long gone are the days when the only "materials processing" carried out was virtually the forming of conventional metals and alloys, and when the development of a new product or process in a great number of cases called for several months of repetitive trial-and-error,' with many (mostly intuition- or experience-based) expensive and time-consuming modifications being made to the dies, until success was achieved. Even when a 'successful' product was formed, its mechanical properties, in terms of springback and dimensional accuracy, thickness variations, residual stresses, surface finish, etc. , remained to be determined. Bulk-forming operations usually required expensive machining to be carried out on the product to impart the required dimensional accuracy and surface fmish. Over the years, the experience-based craft of metal forming has given way to the science of materials processing. With the use of the computer, forming operations can be simulated with accuracy, to determine the best forming route and the associated forming loads and die stresses, and to predict the mechanical properties of the formed product, even down to its surface texture.

Book Description
Examining processes that affect more than 70 percent of consumer products ranging from computers to medical devices and automobiles, this reference presents the latest research in automated plastic injection and die casting mold design and manufacture. It analyzes many industrial examples and methodologies while focusing on the algorithms, implementation procedures, and system architectures that will lead to a fully automated or semi-automated computer-aided injection mold design system (CADIMDS). This invaluable guide in this challenging area of precision engineering summarizes key findings and innovations from the authors' many years of research on intelligent mold design technologies.

Book Description
Managerial Decisions in hierarchy organizations, such as the various manufacturing and service companies, are difficult to formalize and even more difficult to optimize. By exploring the typical fuzziness, vagueness, or the "not-well-defined" nature of such organizations, this book presents the first comprehensive treatment of this difficult and practically important problem. The advantages of the proposed fuzzy interactive approach are that it significantly reduces computational requirements. Equally, the representation of the system is made more realistic through the recognition of the inherent fuzziness of such large organizations. Both the multi-ploy and the game-like decision making processes, also known as multi-level programming and the fuzzy interactive approach, are discussed in detail. The emphasis is on numerical algorithms and numerous examples are solved and compared. The concepts of fuzzy set and fuzzy linguistic representation, which form an integral part of any managerial decision, are also discussed.

Book Description
In order to compete in an increasingly demanding market, many manufacturing companies have to redesign or restructure their manufacturing systems so that a set of coherent manufacturing strategies can be supported. So this book aims to provide a comprehensive treatment of manufacturing strategy analysis (MSA) and manufacturing systems design (MSD). The strategic concerns of manufacturing are linked to subsequent manufacturing systems design activities through the use of an effective MSA/MSD interface. Topics include: A structured approach to formulating manufacturing strategies; A set of linking processes to translate MSA concerns into relevant MSD action plans; Case studies. This book is intended to help graduates and industry-based professionals to make more informed decisions when working on system-design or redesign projects.

Book Description
Applied Metal Forming: Including FEM Analysis describes metal forming theory and how experimental techniques can be used to study any metal forming operation with great accuracy. For each primary class of processes, such as forging, rolling, extrusion, wiredrawing, and sheet-metal forming, it explains how FEA (Finite Element Analysis) can be applied with great precision to characterize the forming condition and in this way optimize the processes. FEA has made it possible to build very realistic FEM-models of any metal forming process, including complex three-dimensional forming operations, in which complex products are shaped by complex dies. Thus, using FEA it is now possible to visualize any metal forming process and to study strain, stresses, and other forming conditions inside the parts being manufactured as they develop throughout the process.

Book Description
Parallel Kinematic Machines (PKMs) are one of the most radical innovations in production equipment. They attempt to combine the dexterity of robots with the accuracy of machine tools to respond to several industrial needs. This book contains the proceedings of the first European-American Forum on Parallel Kinematic Machines, held in Milan, Italy from 31 August - 1 September 1998. The Forum was established to provide institutions, technology suppliers and industrial end users with an improved understanding of the real advantages to be gained from using PKMs. This book contributes to a mid-term strategy oriented to reduce time to market and costs, improve production flexibility and minimize environmental impacts to increase worldwide competitiveness. In particular the authors focus on enabling technologies and emerging concepts for future manufacturing applications of PKMs. Topics include: Current status of PKM R&D in Europe, the USA and Asia. Industrial requirements, roadblocks and application opportunities. Research issues and possibilities. Industrial applications and requirements.
