摘　　要：为了提高数控机床的加工精度,在系统分析数控机床几何误差常用补偿方法基础上,提出了基于数控系统插补数据的几何误差补偿方法,并将误差补偿功能集成于国产数控系统中,以提高国产数控系统的综合性能。通过实验与仿真结果表明,数控系统插补数据的几何误差补偿方案能显著提高数控机床的加工精度。In order to improve the machining accuracy of CNC machine tools, the CNC system interpolated data based geometric er- ror compensation method is proposed on the basis of systematic analysis of the commonly used CNC machine tool geometric error compensation method. The error compensation function is integrated into the domestic CNC system to improve its overall perform- ance. Experiments and simulation show that the CNC system interpolated data based geometric error compensation scheme can im- prove the machining precision.
