Please provide me the PDF, I can make it more precise.
It seems you're asking for a story related to manufacturing science that involves the names Ghosh and Mallik (possibly authors of a well-known textbook) and a PDF reference.
I don't have access to external PDF files or specific documents by Ghosh and Mallik (likely referring to Manufacturing Science by Amitabha Ghosh and Asok Kumar Mallik). However, I can create a short, illustrative story based on the concepts from their book.
Here’s a fictional narrative set in a manufacturing plant, inspired by the principles of metal cutting, tool wear, and process optimization — core topics in Ghosh & Mallik's Manufacturing Science.
Let’s address the elephant in the room. Thousands of students search for a free PDF of this book. While several unauthorized copies float around on websites like Google Drive, Scribd, or Library Genesis, there are significant risks and ethical concerns.
Most engineering students fear derivations. Ghosh and Mallik's genius lies in their incremental derivations. They start with a physical phenomenon (e.g., friction in rolling), write the differential equation, solve it, and explain the physical meaning of the solution.
The publisher sells a direct digital edition. Visit the East-West Press Pvt. Ltd. website and navigate to "Manufacturing Science." They often provide a DRM-protected PDF upon purchase for a fraction of the print cost (approx. INR 300–400).
Hidden within dense paragraphs are nuggets of industrial wisdom. For example: "In practice, cutting fluids are less effective at very high cutting speeds because the fluid cannot penetrate the tool-chip interface due to the high pressure." These statements are gold for interviews.

Each chapter ends with solved examples and unsolved exercises. The numerical problems are challenging—they require modification of formulas, not just plug-and-chug.
Chapter 6: Fundamentals of Plastic Deformation Unlike machining (which removes material), forming changes shape. The authors review the stress-strain curve for ductile materials, yield criteria (Tresca and Von Mises), and flow rules.
Chapter 7: Forging From open-die to closed-die forging. The slab method analysis for forging of rectangular plates and cylinders is a highlight. The concept of friction hill in pressure distribution is unique to this text.
Chapter 8: Rolling Detailed analysis of rolling force, torque, and power. The derivation by Ghosh and Mallik regarding the neutral point (no-slip point) between the roll and the strip is considered a "must-know" for production engineers.
Chapter 9: Extrusion and Drawing Analysis of direct, indirect, and impact extrusion. The book excels in explaining redundant work and friction work in wire drawing.
