摘　　要：对PRS-XY型混联数控机床的关键结构参数误差的快速检测技术进行了研究。提出了影响机床运动精度的关键结构参数,并建立了误差计算模型,进而提出了能够反映机床运动性能的球杆仪测试方案。通过仿真计算,得到了关键结构参数误差对检测结果的影响,并通过实验进行了验证。最终建立了PRS-XY型混联数控机床关键参数误差与检测相关结果的对应关系,为快速误差诊断提供了依据。Based on the PRS-XY type hybrid CNC Machine, some researches were done on rapid test of errors of key structure parameters. Some key structure parameters that affect the motion accuracy of the machine were found, and error model was built. Test way was set. According to the results of calculation, effects of errors of key structure parameters on results of ballbar tracks were got, and were validated by examinations. The relationships between key structure parameters and results of ballbar tracks were got.
