The document discusses the classification of machining processes, focusing on material removal techniques. It categorizes processes into traditional (like turning and milling) and non-traditional methods (such as laser and electrical discharge machining). Key operations and the role of machine tools, specifically lathes, in shaping raw material are also highlighted.

- 3. MACHINING Machining is a processes in which a piece of raw material is cut into a desired final shape and size by a controlled material- removal process.
- 4. MACHINE TOOL • A lathe is a machine tool which rotates the work piece on its axis to perform various operations such as cutting, sanding, knurling, drilling, or deformation with tools that are applied to the work piece to create an object which has symmetry about an axis of rotation.
- 6. MACHINING PROCESSES Include the following: Safety Equipment Metal removing process Unwanted material -- chips or swarfs Raw Work piece Machine Tool Machine Shop Machinist
- 7. MATERIAL REMOVAL PROCESSES A combination of shaping operations, the common feature of which is removal of material from a work piece so the remaining part acquires the desired shape •Categories: Traditional and non traditional processes Machining – It’s a traditional material removal by a Mechanical Equipment and sharp cutting tool, e.g., turning, milling, drilling Abrasive processes –material removal by hard, abrasive particles, e.g., grinding ,sand blasting Non traditional processes - Non traditional processes-various energy forms other than sharp cutting tool to remove material, like chemicals ,laser water jet etc.

- 12. MACHINING • 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. • It requires a mechanical equipment and a sharp cutting tool to remove material • Machining Cutting action involves shear deformation of work material to form a chip • As chip is removed, a new surface is exposed
- 13. MACHINING OPERATIONS Some important machining operations: • Turning • Drilling • Milling Lathe machine Other machining operations: • Shaping and planing • Broaching and hobbing • Sawing and engraving
