: Unlike conventional machining, these methods often have no tool-to-workpiece contact, leading to higher accuracy and better surface finishes. RWD Tool & Machine Ltd. 2. Classification of Processes
Non-conventional (or non-traditional) machining processes remove material using mechanical, thermal, electrical, or chemical energy without direct physical contact or sharp cutting tools. Why we need it: Material Limitations: non conventional machining process ppt updated
| Process | Material Removal Rate (mm³/min) | Surface Finish (Ra, µm) | Tool Wear Ratio | Typical Tolerance (mm) | "Updated" Note | | :--- | :--- | :--- | :--- | :--- | :--- | | | 300 - 600 | 0.1 - 5.0 | 0.1 - 5% (Electrode) | ±0.005 | Dry EDM reduces environmental cost by 90% | | LBM (Femtosecond) | 10 - 100 | 0.05 - 1.0 | Zero contact (No tool) | ±0.002 | Zero HAZ – critical for medical implants | | ECM | 500 - 1500 | 0.05 - 0.8 | 0% (Cathode lasts) | ±0.01 | Pulsed ECM doubles MRR | | USM | 50 - 200 | 0.1 - 0.5 | High (Abrasive slurry) | ±0.02 | RUM reduces cracking in glass | | AJM | 10 - 50 | 0.5 - 1.5 | High (Nozzle wear) | ±0.05 | Nano-abrasives enable die cutting | : Unlike conventional machining, these methods often have
By understanding the principles and applications of non-conventional machining processes, manufacturers can expand their capabilities, improve productivity, and produce high-quality parts with complex shapes and precision finishes. manufacturers can expand their capabilities
