| Research Abstract |
In this research, we developed a high-precision quick-response pneumatic pressure regulator and applied it to the rotation feedback control of an air turbine spindle. We also set a disturbance force observer in the feedback control system, in order to avoid rotation speed change caused by the disturbance force given to the air turbine spindle. By simulation and experiment, the effectiveness of the proposed method is evaluated. Then, an air turbine spindle with the proposed rotation control method is applied to aluminum cutting experiment. The effect of the proposed method on surface roughness is evaluated.
