Manufacturing Engineering and Technology

Manufacturing Engineering and Technology describes both time-tested and modern methods of manufacturing engineering materials.

Preface

The field of manufacturing engineering and technology continues to advance rapidly, transcending disciplines and driving economic growth. This challenging and broad topic has continued to incorporate new concepts at an increasing rate, making manufacturing a dynamic and exciting field of study. In preparing this fourth edition, our most important goal throughout has been to provide a comprehensive state-of-the-art textbook on manufacturing, which also encompasses the additional aims of motivating and challenging students.

As in previous editions, the text presents topics with a balanced coverage of relevant fundamentals and real-world practices, so that the student develops an understanding of the important and often complex interrelationships among the many technical and economic factors involved in manufacturing.

This new edition basically follows the same introductory nature, format, organization, and balance as the third edition. It has retained its emphasis on (a) the influence of materials and processing parameters in understanding manufacturing processes and operations; (b) design considerations, product quality, and manufacturing cost factors; and (c) the domestic and global competitive context of each manufacturing process and operation, highlighted with illustrative examples. STUDY AIDS Presentation of each topic within a larger context of manufacturing engineering and technology, using extensive schematic diagrams and flowcharts. Emphasis on the practical uses of the concepts and information presented. Analogies, discussions, and problems designed to stimulate the student's curiosity about consumer and industrial products and how they are manufactured. Extensive reference material, including numerous tables, illustrations, graphs, and bibliographies. Numerous illustrative examples and case studies to highlight important concepts and techniques. Tables comparing advantages and limitations of manufacturing processes. A summary, list of key terms, and concise description of current trends at the end of each chapter. WHAT IS NEW IN THIS EDITION Several new examples and case studies have been added. There are now a total of almost 2,200 questions and problems, about a quarter of them new to this edition. Summaries at the end of each chapter have been completely rewritten and expanded. The bibliographies at the end of each chapter have been thoroughly updated. More cross-references have been made throughout the text to other sections and chap ters in the book. New or expanded topics include the following:

Abrasive belts; microreplication Atomic force microscope Biodegradable plastics Bundle drawing Carbon foam Chemical mechanical polishing Coatings Compliant end effector Conductive graphite fibers Deburring Diamond-like carbon coating Die failures Die manufacturing methods Electrically conducting adhesives Friction stir welding Hexapod machine tools ISO 14000 standard Joining plastics Laser interferometry Laser peening Linear motor drives for machine tools Microencapsulated powders Microgram carbides Micromachining Nanofabrication Nanomaterials Nanopowders Octree representation Overmolding Plastics, common trade names Porous aluminum Product liability examples Pulsed electrochemical machining QS 9000 standard Rapid prototyping Reflow soldering Robustness Rotary ultrasonic machining Superconductor processing Taguchi loss function Thermal effects in machine tools Titanic: brittle fracture example Total productive maintenance Transfer/injection molding Water-jet peening Wave soldering

In response to comments and suggestions by numerous reviewers, several major and minor changes have also been made throughout the text. A page-by-page comparison with the third edition will show that literally thousands of changes have been made for improved clarity and completeness. AUDIENCE

As in the previous editions, this fourth edition has been written for students in mechanical, manufacturing, industrial, aerospace, and metallurgical and materials engineering programs. It is hoped that by reading and studying this book, students will come to appreciate the vital nature of manufacturing engineering as an academic subject that is as exciting, challenging, and important as any other engineering and technology discipline.
