摘　　要：分析数控蜗杆砂轮磨齿机结构,得出机床全部45项几何误差元素;使用球杆仪对机床平移轴及旋转轴进行误差检测,得到四组机床运动圆轨迹,对机床整体几何精度进行评估,分析得出平移轴为机床几何误差的主要来源,进一步得出影响平移轴精度的主要几何误差元素;最后基于机床几何误差特性,提出机床几何误差简化补偿策略,对快速提升机床几何精度有一定的参考意义。By studying the structure of CNC worm wheel gear grinding machine,45 geometry error elements of the machine tool were obtained. Then results of the circular test for the machine tool were gotten with the help of Ball Bar test to evaluate the geometric accuracy of the machine tools,and the main source of geometric error of the machine tool were studied based on the test results,besides the test results further indicated the main geometric error elements influencing the accuracy of the machine tool. Finally,based on the characteristics of geometric error of the machine tool,a simplified strategy of geometric error compensation of the machine tool were proposed,which is significant to quickly promote the geometric accuracy of the machine tool.
