5-Axis CNC Machining for Aerospace | DMG Mori DMU 40

We start with a 5 pound block of aluminum and machine a precision aerospace part on the ​⁠​⁠‪@DMGMORI‬ DMU 40. In the first setup, the part is clamped in a 5 axis dovetail fixture where we rough and finish all outer surfaces, including critical datums and tight tolerance features. We use 4 axis simultaneous roughing to remove material efficiently, swarf cutting for conical surfaces with a 50 micron profile tolerance, and 3D surfacing to finish angled geometry, all in a single setup. Once the outside is complete, we flip the part into a custom in house fixture designed to support the fragile geometry while we hollow out the core. The inside walls are cut down to just 1 millimeter using a mix of adaptive roughing, plunge finishing, and long reach tooling. We wrap up with 5 axis deburring and a final cleanup pass around the center bore. This is real hardware, built in-house and going into one of our satellites launching soon.
