Sheet Metal Forming Processes And Die Design

This book is a complete modern guide to sheet metal forming processes and die design - still the most commonly used methodology for the mass-production manufacture of aircraft, automobiles, and complex high-precision parts. It illsutrates several dfifferent approaches to theis intricate field by taking the reader through the 'hos' and 'whys' of product analysis, as well as the technqiues for blanking, punching, bending, deep drawing, stretching, material economy, strip design, movement of metal duting stamping, and tooling.

Descripción del editor: "heet forming fundamentals are thoroughly addressed in this comprehensive reference for the practical and efficient use of sheet forming technologies. The principle variables of sheet forming-including the interactions between variables-are clearly explained, as a basic foundation for the most effective use of computer aided modeling in process and die design.Topics include stress analysis, formability criteria, tooling, and materials for sheet forming. The book also covers the latest developments in sheet metal forming technology, including servo-drive presses and their applications, and advanced cushion systems in mechanical and hydraulic presses." (ASM International).

This practical and comprehensive reference gives the latest developments on the design of sheet forming operations, equipment, tooling, and process modeling. Individual chapters cover all major sheet forming processes such as blanking, bending, deep drawing, and more. Process modeling using finite element analysis is described in one chapter and discussed in all appropriate chapters. Other chapters cover sensors and die materials, which are critical for practical sheet forming applications. Other topics include relatively new technologies, such as warm forming of magnesium and aluminum alloys, forming of advanced high-strength steels (AHSS), and hot stamping. Chapters also address special sheet forming operations, like spinning, incremental forming, and mechanical joining, and processes related to sheet forming, such as sheet and tube hydroforming, roll forming, and high-velocity forming.

Material properties -- Sheet deformation processes -- Deformation of sheet in plane stress -- Simplified stamping analysis -- Load instability and tearing -- Bending of sheet -- Simplified analysis of circular shells -- Cylindrical deep drawing -- Stretching circular shells -- Combined bending and tension of sheet -- Hydroforming.

As the only comprehensive text focusing on metal shaping processes, which are still the most widely used processes in the manufacture of products and structures, Metal Shaping Processes carefully presents the fundamentals of metal shaping processes with their relevant applications. The treatment of the subject matter is adequately descriptive for those unfamiliar with the various processes and yet is sufficiently analytical for an introductory academic course in manufacturing. The text, as well as the numerous formulas and illustrations in each chapter, clearly show that shaping processes, as a part of manufacturing engineering, are a complex and interdisciplinary subject. The topics are organized and presented in such a manner that they motivate and challenge students to present technically and economically viable solutions to a wide variety of questions and problems, including product design. It is the perfect textbook for students in mechanical, industrial, and manufacturing engineering programs at both the Associate Degree and Bachelor Degree programs, as well a valuable reference for manufacturing engineers (those who design, execute and maintain the equipment and tools); process engineers (those who plan and engineer the manufacturing steps, equipment, and tooling needed in production); manufacturing managers and supervisors; product design engineers; and maintenance and reliability managers and technicians. Each chapter begins with a brief highlighted outline of the topics to be described. Carefully presents the fundamentals of the particular metal-shaping process with its relevant applications within each chapter, so that the student and teacher can clearly assess the capabilities, limitation, and potentials of the process and its competitive aspects. Features sections on product design considerations, which present guidelines on design for manufacturing in many of the chapters. Offers practical, understandable explanations, even for complex processes. Includes text entries that are coded as in an outline, with these numerical designations carried over the 320 related illustrations for easy cross-referencing. Provides a dual (ISO and USA) unit system. Contains end-of-chapter Review Questions. Includes a chapter on sheet metalworking covering cutting processes; bending process; tubes and pipe bending; deep drawing processes; other sheet metal forming process (stretch forming, spinning, rubber forming, and superplatic forming and diffusion bonding). Provides a useful die classification with 15 illustrations and description; presses for sheet metalworking; and high energy-rate forming processes. A chapter on nontraditional manufacturing process discusses such important processes as mechanical energy processes (ultrasonic machining, water jet cutting); electrochemical machining processes (electrochemical machining, electrochemical grinding); thermal energy processes (electric discharge processes, laser beam machining, electron beam machining); and chemical processes (chemical milling).

The concept of virtual manufacturing has been developed in order to increase the industrial performances, being one of the most ef cient ways of reducing the m- ufacturing times and improving the quality of the products. Numerical simulation of metal forming processes, as a component of the virtual manufacturing process, has a very important contribution to the reduction of the lead time. The nite element method is currently the most widely used numerical procedure for s- ulating sheet metal forming processes. The accuracy of the simulation programs used in industry is in uenced by the constitutive models and the forming limit curves models incorporated in their structure. From the above discussion, we can distinguish a very strong connection between virtual manufacturing as a general concept, ?nite element method as a numerical analysis instrument and constitutive laws,aswellas forming limit curves as a speci city of the sheet metal forming processes. Consequently, the material modeling is strategic when models of reality have to be built. The book gives a synthetic presentation of the research performed in the eld of sheet metal forming simulation during more than 20 years by the members of three international teams: the Research Centre on Sheet Metal Forming—CERTETA (Technical University of Cluj-Napoca, Romania); AutoForm Company from Zürich, Switzerland and VOLVO automotive company from Sweden. The rst chapter presents an overview of different Finite Element (FE) formu- tions used for sheet metal forming simulation, now and in the past.

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.
