Methods of improving machining precision are presented for the flexible-manufacturing system. Firstly, the methods of orientation precision are obtained based on the error of the flexile manufacturing system and the factors affecting precision of numerical controlled machine tool. Then, the model of numerically con- trolled machine is built up and the motionless of numerically controlled machine is analyzed. Further, some ways are presented to deduce the motionless. Finally, the solution of improving machining precision of flexible manufacturing system, and introduced the principle and methods of orientation precision error compensation.
