Title: Your Go-To Guide for Metal Cutting & Machine Tools? Still P.N. Rao’s Volume 2.
In the world of manufacturing engineering, some books become timeless references. "Manufacturing Technology, Volume 2" by P.N. Rao is one of them.
While Volume 1 covers casting, forming, and joining, Volume 2 dives deep into the science of metal cutting and machine tools.
🔧 What makes this book a staple on every engineer’s shelf?
✅ Process clarity: From lathe and milling to grinding and gear cutting—Rao breaks down complex kinematics with simple line diagrams. ✅ Tool geometry: Master the ASA and ORS systems (a must for GATE & competitive exams). ✅ Cutting mechanics: Understand shear angle, cutting forces, tool life equations, and surface finish like a pro. ✅ Modern processes: Includes NC/CNC, jigs and fixtures, and non-traditional machining (EDM, USM, LBM).
Whether you're a diploma student, a practicing machinist, or prepping for an engineering interview, this book bridges the gap between theory and shop-floor reality.
📌 Favorite takeaway: The chapter on "Economics of Machining" — a perfect blend of production targets and cost optimization.

📢 Book Recommendation:
Manufacturing Technology – Volume 2
Author: P.N. Rao
Publisher: McGraw Hill Education
Best for:
- Understanding conventional & non-conventional machining
- Machine tool design basics
- Numerical problems on machining time, cutting speed, and tool wear
🆚 How it differs from Vol 1: Vol 1 = Casting, forming, welding. Vol 2 = Machining, cutting tools, CNC, and metrology (partially).
Available in paperback & e-book. Still relevant even after 20+ years.
Manufacturing Technology Volume 2: Metal Cutting and Machine Tools
by P.N. Rao is a cornerstone textbook for undergraduate mechanical and production engineering students. While Volume 1 focuses on foundry, forming, and welding, Volume 2 delves into the subtractive processes and the sophisticated machinery used to achieve high precision in modern manufacturing.

How to Study Using Manufacturing Technology Volume 2
To maximize output from this textbook, follow this strategy: Post Option 1: For LinkedIn / Professional Engineers
- Start with Chapter 1 (Theory of Metal Cutting): Do not skip the derivations. Practice drawing the Merchant’s Circle freehand until it is second nature.
- Memorize the Standard Tables: Rao provides tables for cutting speeds for different materials and tool life constants. Keep these bookmarked.
- Focus on Numerical Problems: For GATE, at least 2–3 questions come directly from Taylor’s tool life or cutting force calculation. Rao’s unsolved problems are gold.
- Use the Indexing chapter: For gear manufacturing, draw the kinematic diagrams of a hobbing machine.
4. Jigs & Fixtures
For production engineers, holding the workpiece correctly is half the battle. Rao’s treatment of Jigs and Fixtures is famous for its practical drawings.
- Principles of Location: 3-2-1 principle of location.
- Clamping Devices: Types of clamps (strap, screw, cam, hydraulic).
- Difference between Jig and Fixture: Jigs guide the tool (drill jigs); fixtures hold the work for milling or grinding.
- Indexing Mechanisms: Used for multi-sided machining.
2.2 Tool Wear and Tool Life
Tool failure is rarely a catastrophic break; it is usually a gradual wear process. The Taylor’s Tool Life Equation ($VT^n = C$) is a central concept in this volume.
- Flank Wear: Occurs on the clearance face; generally used as the criteria for tool life limits.
- Crater Wear: Occurs on the rake face where the chip rubs; common in high-speed steel machining of steel.
