摘　　要：以PRS-XY型混联数控机床为对象,以加工、装配精度为依据,建立该机床完整的误差模型。设计能反映机床运动精度的典型轨迹,利用该轨迹,通过对该模型的求解和分析,得出主要误差源对机床运动精度的影响。为指导该混联机床的精度设计和误差补偿提供了数据。Based on the PRS-XY type hybrid Parallel CNC machine developed, a whole error model has been built according to manufacturing and assembly. A track that can reflect the move precision of the machine was designed. Using it , calculated and analyzed the model, and got effects on the move precision that caused by main error soures. And they can provide basis of theories and practices for design and compensation.
