Newly revised for its twelfth edition, DeGarmo’s Materials and Processes in Manufacturing, 12th Edition continues to be a market-leading text on manufacturing and manufacturing processes courses for over fifty years. Authors J T. Black and Ron Kohser have maintained the book’s long and distinguished tradition of clear presentation and practical approach, presenting mathematical models and analytical equations only when they enhance basic understanding. Updated to reflect all current practices, standards, and materials, the twelfth edition includes new coverage of additive manufacturing, lean engineering, and processes related to ceramics, polymers, and plastics.
