Guiding engineering and technology students for over five decades, DeGarmo's Materials and Processes in Manufacturing provides a comprehensive introduction to manufacturing materials, systems, and processes. Coverage of materials focuses on properties and behavior, favoring a practical approach over complex mathematics; analytical equations and mathematical models are only presented when they strengthen comprehension and provide clarity. Material production processes are examined in the context of practical application to promote efficient understanding of basic principles, and broad coverage of manufacturing processes illustrates the mechanisms of each while exploring their respective advantages and limitations.
Aiming for both accessibility and completeness, this text offers introductory students a comprehensive guide to material behavior and selection, measurement and inspection, machining, fabrication, molding, fastening, and other important processes using plastics, ceramics, composites, and ferrous and nonferrous metals and alloys. This extensive overview of the field gives students a solid foundation for advanced study in any area of engineering, manufacturing, and technology.
