This paper presents a multi-step design optimization for 5-axes multi-tasking machine using a genetic algorithm. The design problem is to find out thickness of structural members which minimize vibrations, the static compliance, dynamic compliance and weights of the machine structure simultaneously under several constraints such as dimensional constraints, maximum deflection limit, safety criterion and maximum vibration amplitude limit. Optimization results showed a little reduction in compliance and vibration amplitude at the spindle nose of the 5-axes multi-tasking machine in spite of being decreased machine weight.
