Thin wall machining. Aerospace skins. Lightweight CNC.
Thin-wall machining — CNC of parts with walls < 2 mm. Aerospace skins, ribs, lattice structures. Vibration management, fixturing, slow cuts.
Thin wall machining
Specialty fixturing, slower speeds, multi-pass cutting, vibration management. 2-3× standard CNC time.
Key principles.
Critical
Thin walls vibrate during cutting. Vibration causes chatter, poor finish, dimensional issues.
Internal
Internal supports during machining. Removed after.
Slow, light
Slow speeds, light depths of cut, fine pitches. Multiple passes.
Sharp, small
Small-diameter, sharp tools. Reduce cutting forces.
During & after
Stress in material released during machining. Plan for distortion.
Skins, ribs
F-22 skins, satellite structures, drone components.
FAQ
Aluminum 0.5-0.8 mm achievable. Steel 0.8-1 mm. Practical limit varies.
Specialty fixturing, slower speeds, multi-pass cutting, vibration management. 2-3× standard CNC time.
Chatter (poor finish), distortion (wall warping), breakage (handling damage).
Pre-machining stress relief. Multi-stage machining (rough, stress relief, finish).
±0.025 mm achievable on thin-wall parts with proper process control.
Aluminum 6061/7075. Titanium grade 2/5. Stainless 17-4 PH. Each per application.
