Sheet Metal Forming Processes And Die Design. By an engineer with decades of practical manufacturing experience, 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 illustrates several different approaches to this intricate field by taking the reader through the “hows” and “whys” of product analysis, as well as the techniques for blanking, punching, bending, deep drawing, stretching, material economy, strip design, movement of metal during stamping, and tooling. While concentrating on simple, applicable engineering methods rather than complex numerical techniques, this practical reference makes it easier for readers to understand the subject by using numerous illustrations, tables, and charts. Emphasizes the influence of materials as an aid to understanding manufacturing processes and operations. Features the essential mathematical formulas and calculations needed for various die operations and performance evaluation. Shows the comparative advantages and liabilities for each manufacturing process and operation. Offers a complete picture of the knowledge and skills needed for the effective design of dies for sheet-metal forming processes highlighted with illustrative examples. Provides properties and typical applications of selected tool and die materials for various die parts.

Mechanics Of Sheet Metal Forming. The basic theory of sheet metal forming in the automotive, appliance and aircraft industries is given. This fills a gap between the descriptive treatments in most manufacturing texts and the advanced numerical methods used in computer-aided-design systems. The book may be used by lecturers in undergraduate courses in manufacturing; plentiful exercises and worked examples provide quantitative tutorial problems for students. A separate, but related simulation software package advertised on this page enables students to explore the limits of processes and understand the influence of different process and material variables. Engineers in stamping plants and press shops find the book useful in understanding what happens during forming and why failures occur. The book is also used as a text for industrial short courses that have been given in many countries. Die designers and tooling engineers find the simple treatment of processes useful at the conceptual design stage and also in determining modifications needed to overcome problems indicated by detailed numerical analysis. The original text, published 10 years ago, has been completely rewritten for this edition and newer topics such as hydroforming included. Simple equations governing plastic deformation, press forming, bending, punch stretching and deep drawing are derived and explained. The aim is to provide simple applicable methods rather than complex numerical techniques for practising engineers and for students interested in a quantitative and practical approach. SIMPLIFIED STAMPING SIMULATION SOFTWARE "4S' The analytical treatment in this book is used to develop simulation modules for simple cases of sheet forming such as stamping, deep drawing, bending and hydroforming. Students can investigate the influence of tooling dimensions, material properties and process variables such as friction on the outcome of operations and see from animated models how, for example, press loads develop during forming. Applications using this package greatly enhance interest in the development of theory in the book. The website provides further information and an opportunity to run some of the modules. Presents the fundamentals of sheet metal forming - bending, stretching, press forming, deep drawing and hydroforming Shows how deformation, loads and process limits can be calculated using simple equations Concentrates on simple, applicable methods rather than complex numerical techniques Contains many exercises, worked examples and solutions Used as a reference text in undergraduate manufacturing courses, as a required text in specialist graduate courses and as a course text for industrial short courses Is supported by a separate, but related simulation software package described below

Design And Optimization Under Uncertainty In Sheet Metal Forming Processes Constrained With Failure Analysis. Through the integration of these features, the current research establishes a framework for design under uncertainty in sheet metal forming. The robust design model takes into account producibility requirements through failure analysis and uncertainties from forming conditions and material properties. The approach was demonstrated through a demonstration example of a wheelhouse stamping process used in automobile industry. In addition, model validation approaches taking uncertainty into account are demonstrated in a simulation of a sample flanging process. Overall, this research presents the methodology and feasibility of implementing the framework for design and optimization under uncertainty, which can certainly be generalized for other industrial cases.

Die Design Methodology For Pulsed Sheet Metal Forming Processes. In high-speed sheet metal forming processes impact is concentrated over a small contact area, and the resulting contact stress can compromise the structural integrity of the die. It is important to accurately predict the associated workpiece/tooling interface loads, so that engineers can more confidently propose robust die designs. The foundation for accurate predictions of contact stress on die is a reliable contact model within the context of a finite element simulation. In the literature, however, there exists no comprehensive guideline for establishing a contact model for high-speed sheet metal forming processes using the finite element method. In this work, a mathematically justified contact model and modeling recommendations are offered for the electrohydraulic forming process. The model will focus on aspects such as contact algorithm, mesh size and time step size that are known to play essential roles in providing accurate results in modelling of such high-speed processes.

Metal Forming Handbook. 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.

Ai Applications In Sheet Metal Forming. This book comprises chapters on research work done around the globe in the area of artificial intelligence (AI) applications in sheet metal forming. The first chapter offers an introduction to various AI techniques and sheet metal forming, while subsequent chapters describe traditional procedures/methods used in various sheet metal forming processes, and focus on the automation of those processes by means of AI techniques, such as KBS, ANN, GA, CBR, etc. Feature recognition and the manufacturability assessment of sheet metal parts, process planning, strip-layout design, selecting the type and size of die components, die modeling, and predicting die life are some of the most important aspects of sheet metal work. Traditionally, these activities are highly experience-based, tedious and time consuming. In response, researchers in several countries have applied various AI techniques to automate these activities, which are covered in this book. This book will be useful for engineers working in sheet metal industries, and will serve to provide future direction to young researchers and students working in the area.
