Abstract: The paper puts forward a method that the internal force greatly improves the actual accuracy of parallel machine tools, and a-2DOF redundantly actuated parallel mechanism is designed. The position and speed harmonious control conditions is studied and the force control system is devised in this paper. The experiments show that this method can greatly improve the accuracy of parallel machines. Therefore, the results provide the theoretical and experimental foundation for improving the accuracy of parallel machi…
