Aluminiozko zoru meheen fresaketa: erronkak, teknikak eta gidalerroak

Aluminium thin floors have many industrial uses, especially as aircraft fuselage. Their manufacturing involves many operations, and the last one is the most critical one. This operation is mechanical milling, and it entails important challenges, as reducing distortion as consequence of residual stre...
