Processing Requirements

Superalloy blades require shaped film cooling holes at 0.3-0.5mm diameter with ±0.5° angle precision

Technical Solution

5-axis simultaneous laser processing system with adaptive path planning and in-line inspection

Processing Results

• Angle deviation <±0.3°
• No micro-cracks on hole walls
• 15% improvement in blade fatigue life
