This book, volume three of the second edition of the comprehensive Handbook of Manufacturing Engineering, focuses on establishing essential communication between manufacturing and design engineers. Such communication is essential to ensure effective debugging of machinery, a critical, methodical procedure used to uncover and eliminate problems encountered in the initial startup. The book suggests efficient deductive and systematic approaches to machine debugging while providing a refresher on the principles of structural mechanics. Coverage then extends to material characteristics of metals, conventional fabrication processes, laser welding, modeling, and nontraditional machining methods.
