Description
For advanced undergraduate or first-year graduate courses in CAD/CAM, manufacturing systems, and manufacturing control in industrial and mechanical engineering departments.
Using a strong science-based and analytical approach, this text provides a modern description of CAM from an engineering perspective to include design specification, process engineering, and production. It begins with discussions of part design and geometric modeling and then gives detailed coverage of individual technologies and building blocks to provide readers with a clear understanding of CAM technology. Unlike most other texts in the field, this book includes both descriptive information and analytical models.

Preface
The paradigm of engineering is undergoing a major evolution throughout the world. The use of computers and the Internet has changed the way that we engineer and manufacture products. Among the recent trends in manufacturing are trends in which products are subject to a shorter product life, frequent design changes, small lot sizes, and small in-process inventory restrictions ("lean manufacturing"). The result of these trends is that today more than 90% of our products are manufactured in lots of less than 50 parts. These low lot quantities have eliminated many applications of dedicated production lines that were so effective in producing the inexpensive goods of the 1950 and 1960s.
The first step the nation employed to remain competitive with our international counterparts was the application of computer-aided design (CAD) and computer-aided manufacturing (CAM) to design and manufacture sophisticated products. Today, we routinely employ CAD to design products and flexible or programmable manufacturing systems to produce low- to medium-volume batch quantities. The Internet provides us with the connection to share design, marketing, and manufacturing information. We now look toward the advent of distributed design and manufacturing using agile networking as a means to produce products for the twenty-first century.
Employing numerical control (NC) and robotics in industry offers one potential solution to many manufacturing flexibility problems. This implementation, however, brings with it a variety of other problems. Robots and NC machines are designed to be flexible, self-contained, and capable of operating in both "stand-alone" and "integrated" manufacturing environs. Integrating this hardware into manageable systems has become a major focus of machine-tool makers and industry. Individual NC machines have also been made more versatile, more precise, more rigid and durable, and faster. More complex parts can be machined with higher accuracy and in less time. Timecompressed manufacturing technologies such as NC and rapid prototyping are being used more routinely to shorten product development cycles and to produce one-of-a-kind products. The benefit of all these new technologies cannot be achieved without the "communication networks" or an understanding of how these activities fit together. Today, it is not unusual for a design made thousands of miles away to be transferred to and realized in a remote site. Part programs and control instructions are downloaded from offices to machine controllers. Shop-floor operations can also be monitored either on-site or from afar. Manufacturing equipment has become part of the supply chain; capacity and availability are parameters used in planning and control of the entire chain. Further integration of the manufacturing component with design and business systems is also a key to our manufacturing success. These communication and control issues, coupled with a variety of sensing issues, are critical to the success of flexible automation in the United States.
This book focuses on the science, mathematics, and engineering of these new engineering methods. It is dedicated to making sure that the United States will remain the most efficient manufacturing nation in the world. The purpose of the book is to provide a comprehensive view of manufacturing, with a focus on design, automation, flexible automation, and the use of computers in manufacturing (CIM). Unlike other CIM books, this one attempts to provide a strong analytical science base and background in computer-aided manufacturing systems. The book is an excellent professional reference and also is an excellent text for CAM instruction.
We would like to thank the reviewers who provided feedback on the several drafts of this edition: Jeanette M. Garr, Youngstown State University; Nicholas G. Odrey, Lehigh University; Gary E. Rafe, The University of Toledo; Robert P Van Til, Oakland University; and Gongyao (Jack) Zhou, Drexel University.
The book is written for advanced undergraduate and graduate courses. Each chapter covers general background, fundamental principles, and applications. Unlike most other manufacturing books on the market, it includes both descriptive information and analytical models. Whenever possible, MATLAB is used in examples. We do not assume that readers have a significant background beyond basic undergraduate engineering courses. However, the book does cover a very wide range of technologies and methodologies. Readers will gain in-depth and practical knowledge in CAM technologies.
