This publication has been written to honour the contribution to science and education made by the Distinguished Professor Emeritus Professor Schey on his eightieth birthday. The contributors to his book are among the countless researchers who have read, studied and learned from Professor Schey's work, which includes books, research monographs, invited papers, keynote papers, scientific journals and conferences. The topics include manufacturing, sheet and bulk metal forming and tribology, amongst others. The topics included in this book include: John Schey and value-added manufacturing; Surface finish and friction in cold-metal rolling; Direct observation of interface for tribology in metal forming; An examination of the coefficient of friction; Studies on micro plasto hydrodynamic lubrication in metal forming; Numerical simulation of sheet metal forming; Geometric and mechanics model of sheet forming; Modelling and optimisation of metal forming processes; The mathematical modelling of hot rolling steel; Identification of rheological and tribological parameters; Oxide behaviour in hot rolling; Friction, lubrication and surface response in wire drawing; and Modelling and control of temper rolling and skin pass rolling.

On October 21 and 22, 1970, the Shaping and Forming Committee, Institute of Metals Division, The Metallurgical Society of AlME, held a Conference on "The Relation Between Theory and Practice it). Metal Forming" at the Sheraton-Cleveland Hotel during the Fall Meeting of AIME in Cleveland, Ohio. This conference was devoted to recent applications of theory to metal forming to establish a milestone in the current ability to predict phenomena during deformation processing and, thereby, demonstrate the utility of theory for process design. The papers were selected by first requesting presentations of relevant recent work from 68 recognized authorities in metal forming which resulted in 17 papers. A sub sequent call for papers resulted in the submission of 19 abstracts from which 4 papers were selected. The selection criteria required that the paper coupled theory with practice, and that the work was recent, unpublished and worthy of permanent record. The selection was performed by the Conference Chairman. The papers in this volume have been organized in accordance with the following subjects: Extrusion Drawing and Sheet Metal Forming Forming Loads and Friction Workability These papers appear to assess the salient recent applications of mechanics to the deformation processing of alloys at the present time, i. e. , circa 1970, A, L.

Metal Forming: Formability, Simulation, and Tool Design focuses on metal formability, finite element modeling, and tool design, providing readers with an integrated overview of the theory, experimentation and practice of metal forming. The book includes formability and finite element topics, including insights on plastic instability, necking, nucleation and coalescence of voids. Chapters discuss the finite element method, including its accuracy, reliability and validity and finite element flow formulation, helping readers understand finite element formulations, iterative solution methods, friction and contact between objects, and other factors. The book's final sections discuss tool design for cold, warm and hot forming processes. Examples of tools, design guidelines, and information related to tool materials, lubricants, finishes, and tool failure are included as well. Provides fundamental, integrated knowledge on metal formability, finite element topics and tool design Outlines user perspectives on accuracy, reliability and validity of finite element modeling Discusses examples of tools, their design guidelines, tool lubricants, and tool failure Considers the role played by stress triaxiality and shear and introduces uncoupled ductile damage criteria Includes applications, worked examples and detailed techniques

This sourcebook presents the most important metal-working and shearing processes - and their related machines and tooling - in a concise form supplemented by ample illustrations, tables and flow charts. Practical examples show how to calculate forces and strain energy of the processes and the specific parameters of the machines, and exercises help readers improve understanding. Because much production today is automated using modern Computer Numerical Control engineering, the book covers automated flexible metal forming and handling systems. Carefully translated from the eighth revised German-language edition, Metal Forming Practise offers a valuable reference tool for students, engineers and technicians.

Following the long tradition of the Schuler Company, the Metal For ming Handbook presents the scientific fundamentals of metal forming technology in a way which is both compact and easily understood. Thus, this book makes the theory and practice of this field accessible to teaching and practical implementation. The first Schuler "Metal Forming Handbook" was published in 1930. The last edition of 1966, already revised four times, was translated into a number of languages, and met with resounding approval around the globe. Over the last 30 years, the field of forming technology has been rad ically changed by a number of innovations. New forming techniques and extended product design possibilities have been developed and introduced. This Metal Forming Handbook has been fundamentally revised to take account of these technological changes. It is both a text book and a reference work whose initial chapters are concerned to pro vide a survey of the fundamental processes of forming technology and press design. The book then goes on to provide an in-depth study of the major fields of sheet metal forming, cutting, hydroforming and solid forming. A large number of relevant calculations offers state of the art solutions in the field of metal forming technology. In presenting tech nical explanations, particular emphasis was placed on easily under standable graphic visualization. All illustrations and diagrams were compiled using a standardized system of functionally oriented color codes with a view to aiding the reader's understanding.

The pressing of sheet metal into useful shapes is a technology which requires an understanding of a wide range of subjects. This text is divided into three sections: processes, materials and tests. In Part 1, sheet metal forming is examined mainly from a mechanical engineering viewpoint; firstly plasticity and anisotropy, then process variables - friction, lubrication and temperature - and finally practical aspects of forming in the press-shop. Part 2 deals with the main sheet alloys at varying lengths, depending on their industrial popularity. Certain research results, showing the fallibility of the phenomenological approach, are also highlighted. A section of testing procedures concludes the volume.
