Students must keep up with developments in analytical modeling of machining processes, modern cutting tool materials, and how these changes affect the economics of machining. With coverage reflecting state-of-the-art industry practice, Fundamentals of Machining and Machine Tools, This Edition emphasizes underlying concepts, analytical methods, and economic considerations, requiring only basic mathematics and physics. This book thoroughly illustrates the causes of various phenomena and their effects on machining practice. The authors include several descriptions of modern analytical methods, outlining the strengths and weaknesses of the various modeling approaches. Supplying abundant examples, illustrations, and homework problems, Fundamentals of Machining and Machine Tools, Third Edition is an ideal textbook for senior undergraduate and graduate students studying metal cutting, machining, machine tool technology, machining applications, and manufacturing processes.
Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing ,  in distinction from processes of controlled material addition, which are known as additive manufacturing. Exactly what the "controlled" part of the definition implies can vary, but it almost always implies the use of machine tools in addition to just power tools and hand tools. Machining is a part of the manufacture of many metal products, but it can also be used on materials such as wood , plastic , ceramic , and composites. A room, building, or company where machining is done is called a machine shop.
