The development period can be shortened by applying model-based development, which has been attracting attention in recent years, to machine tools. In this research, we will identify the necessary parameters in order to apply the model-based development to the moving table by ball screw drive system, which is indispensable for machine tools. Guide friction, friction torque, rigidity, and damping coefficient were identified using a rotary encoder, linear scale, and force gauge. Simulation is possible with the identified guide friction, starting torque, stiffness, and damping coefficient. In the future, it will be possible to estimate the cutting force and control using a disturbance observer.
