The revised version of this comprehensive pocket reference guide is ideal for anyone who deals with physics, chemistry, mathematics, finance, and computer systems and needs to review or quickly refresh their memory of what they studied in school.

Written by an engineer with decades of practical manufacturing experience, this new edition has been thoroughly revised and 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. Included are 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. Its focus is on simple, applicable engineering methods rather than complex numerical techniques. It emphasizes the influence of materials as an aid to understanding manufacturing processes and operations. It features the essential mathematical formulas and calculations needed for various die operations and performance evaluation. It shows the comparative advantages and liabilities for each manufacturing process and operation. It 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. It provides properties and typical applications of selected tool and die materials for various die parts.

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 in this book begins with a brief highlighted outline of the topics to be described. This title 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. It features sections on product design considerations, which present guidelines on design for manufacturing in many of the chapters. It offers practical, understandable explanations, even for complex processes. It includes text entries that are coded as in an outline, with these numerical designations carried over the 320 related illustrations for easy cross-referencing. It provides a dual (ISO and USA) unit system. It contains end-of-chapter Review Questions. It also includes a chapter on sheet metalworking covering cutting processes; bending process; tubes and pipe bending; deep drawing processes; and, other sheet metal forming process (stretch forming, spinning, rubber forming, and superplatic forming and diffusion bonding). It also provides a useful die classification with 15 illustrations and description; presses for sheet metalworking; and, high energy-rate forming processes.

Finally, in a single volume, a reference that presents engineering-level information on press-working sheet metal, die design, and die manufacturing!

Retaining its unique and much praised organization, this leading text has been revised to reflect the most recent developments in design tools. It provides balanced coverage of relevant fundamentals and real-world practices so that students, apprentices and on-the-job professionals can understand the important and often complex interrelationships between die design and the economic factors involved in manufacturing sheet-metal forming products. Following introductory material and a discussion of 20 types of dies in Chapter 2, the design process of a representative die is separated into seventeen distinct chapters. Each chapter is one step which is illustrated in two ways; first, as a portion of an engineering drawing, that is, as the component is actually drawn on the design. Second, the die design is shown pictorially in order to improve the user’s visualization. In successive sections each step is detailed as it is applied to the design of the various types of dies listed in Chapter 2.   Includes English and Metric systems.Covers new methods of producing blanks, such as waterjet cutting and laser cutting.Contains a glossary of terms for the first time.Illustrates each step in pictorial view and as a portion of an engineering drawing.Offers a completely revised chapter on presses and quick die-changing systems and includes the addition of "Quick Die Change Systems".Introduction to Die Design Classifications and Types of Dies The Material Strips The Blank Fourteen Steps to Design a Die How to Lay Out a Scrap Strip How to Design Die Blocks How to Design Blanking Punches How to Design Piercing Punches How to Design Punch Plates How to Design Pilots How to Design Gages How to Design Finger Stops How to Design Automatic Stops How to Design Strippers How to Apply Fasteners How to Select a Die Set Dimensions and Notes The Bill of Material Presses and Quick Die-Changing SystemsGlossaryIndex
