Design for Advanced Manufacturing: Technologies and Processes
Autor LaRoux Gillespieen Limba Engleză Hardback – 16 apr 2017
Expertly edited by a past president of the Society of Manufacturing Engineers, this state-of-the-art resource picks up where the bestselling Design for Manufacturability Handbook left off. Within its pages, readers will find detailed, clearly written coverage of the materials, technologies, and processes that have been developed and adopted in the manufacturing industry over the past sixteen years. More than this, the book also includes hard-to-find technical guidance and application information that can be used on the job to actually apply these cutting-edge processes and technologies in a real-world setting. Essential for manufacturing engineers and designers, Design for Manufacturability is enhanced by a host of international contributors, making the book a true global resource.
• Information on the latest technologies and processes such as 3-D printing, nanotechnology, laser cutting, prototyping, additive manufacturing, and CAD/CAM software tools
• Coverage of new materials including nano, smart, and shape-memory alloys, in steels, glass, plastics, and composites
• Supplemental content includes tolerance charts, graphs, curriculum guides, certification practice, and videos
