The transition from manual machining to numerical control is a core theme in the latter half of the book. It introduces Computer Numerical Control (CNC) machines, discussing their structural elements, recirculating ball screws, and feedback devices. Students learn the fundamentals of CNC part programming, including G-codes and M-codes, fixed cycles, and computer-assisted programming. Non-Traditional Machining (NTM) manufacturing technology volume 2 - P.N Rao
Whether you are preparing for competitive exams like GATE or IES, or you are a design engineer trying to understand the manufacturability of a part, is a necessary resident on your bookshelf. It is more than a textbook; it is a blueprint for how the modern world is built. | Section | Key Topics Covered | |
The book establishes a strong foundation in the mechanics of machining. It details how chips form when a tool engages a workpiece. Rao explains the physics of orthogonal and oblique cutting. He uses Merchant's force analysis to help readers calculate cutting forces, power consumption, and shear angles. The text thoroughly explores tool wear mechanisms, tool life equations (such as Taylor's tool life model), and the critical role of cutting fluids in reducing heat and friction. Traditional Machine Tools | | III
The economics of manufacturing depend heavily on tool life. The book covers tool wear mechanisms (crater wear and flank wear) and utilizes Taylor’s Tool Life Equation ( ) to demonstrate how cutting speed ( ) drastically impacts tool longevity ( ) compared to feed rate and depth of cut. 3. Conventional Machine Tools and Operations
: Construction of center lathes, operations (turning, facing, threading), and special-purpose lathes. Reciprocating Machines : Shapers, planers, and slotters.
