Mastering the Future of Manufacturing: The Ultimate Guide to Non Conventional Machining Process PPT
Slide 8: Electro-Chemical Process – ECM (Electrochemical Machining)
- Principle: Reverse electroplating (Anodic dissolution at ~20 V, high current).
- Faraday’s Law: Material removal follows electrolysis.
- Advantages: No tool wear, no heat, burr-free.
- Disadvantage: High energy cost, hydrogen evolution.
Presentation Guide: Non-Conventional Machining Processes
Slide 4: Laser Beam Machining (LBM) – Light as a Blade
- Working Principle: High-power density (10⁸ W/mm²) light beam melts and vaporizes material.
- Types: Nd:YAG, CO₂, Fiber lasers.
- Capabilities: Drilling holes as small as 0.005 mm, cutting complex 2D profiles.
- Use Case: Stent cutting in medical devices, cooling holes in jet engine blades.
Slide 10: Comparison – Conventional vs Non-Conventional
| Parameter | Conventional | Non-Conventional |
|-----------|--------------|------------------|
| Tool contact | Yes | No |
| Material hardness | Limiting factor | No issue |
| MRR | High | Low to moderate |
| Surface finish | Good | Excellent (except thermal) |
| Initial cost | Low | High |
