Abstrakt: This paper proposed a new ballonet polishing method for the precise polishing of aspheric parts. The method is based on the integration of a MRT (Magnetorheological fluid Torque servo)-based ballonet polishing tool system and a CNC lathe. By using this method, the decoupling control of force-position-posture can be realized in polishing process. The structure and working principle of the polishing tool system were introduced. The material removal model for ballonet polishing was established according to Preston Equation. The main factors affecting the material removal were discussed, and the control model of uniform removal was put forward.
