摘　　要：利用先进的检测设备对数控铣床热误差进行检测与分析,使用Labview搭建了数据检测与分析的平台。在研究球杆仪检测数控机床热误差的方法的基础上,对数控机床空间几何位置和主轴端热漂移误差进行了分析。通过实验测得热误差进行曲线拟合,得到变化规律曲线,实验结果证明该实验方法和检测与分析平台的实用性和有效性。By using advanced testing equipment to detect and analyse CNC milling thermalerror,we employ Labviewto set up the platform of data detection and analysis. Based on the research of detective method of CNC Machine Thermal Error on ballbars,we analyse spatial geometry of CNC machine tool spindle thermal drift and error. By experimentally measured thermal error curve fitting,we obtained curve variation. The experimental results showthat the experimental methods and the platform of detection and analysis are practicability and effective.
