Non-Conventional Machining Processes: Beyond the Cutting Tool
4. Industrial Case Study: Turbine Blade Cooling Holes A nickel-based superalloy turbine blade requires 50-80 angled cooling holes (<0.5 mm diameter). Conventional drilling fails due to tool breakage. Laser Beam Machining (LBM) drills holes in 0.2 seconds per hole but leaves a recast layer requiring secondary polishing. EDM provides a cleaner hole but takes 15 seconds per hole. The industry trend is "Laser roughing + ECM finishing." Non Conventional Machining Process Ppt
Slide 11: Comparison – Conventional vs Non-Conventional
| Parameter | Conventional | Non-Conventional | |---------------|------------------|----------------------| | Tool contact | Yes | No (or minimal) | | Material hardness limit | Soft to medium | Any hardness | | Heat generation | High | Low to none (except thermal methods) | | Surface finish | Moderate | Good to excellent | | Complexity | Simple shapes | Intricate, micro features | | Cost | Low to moderate | High equipment cost | Working Principle : High-pressure water (up to 6,000
This report outlines the essential structure and content for a presentation on Non-Conventional Machining Processes (NCMP), also known as Unconventional or Modern Machining. These processes are critical for manufacturing complex shapes in advanced materials that are too hard or brittle for traditional tools. 1.

Slide 6: Abrasive Water Jet Machining (AWJM) – Cold Cutting
- Working Principle: High-pressure water (up to 6,000 bar) mixed with garnet abrasives cuts through materials.
- Unique Selling Point: No heat-affected zone (cold cutting process). Can cut 10-inch thick titanium.
- Also Cuts: Composites, stone, glass, rubber, food (water-only).
