摘　　要：文章采用水平分割法确定误差补偿点,对3种运动指令修改算法,实现定位指令、直线插补指令和圆弧插补指令的算法修改。在FANUC Series oi-mate系统VMC-850立式加工中心上运行基于修改NC程序的误差补偿软件,进行对比验证,结果表明补偿后加工精度提高30%左右。In this paper,the horizontal division method is used to determine the error compensation point.Three motion command algorithms are modified,the algorithm modification of positioning com-mand,linear interpolation command and arc interpolation command is realized.For comparative verifi-cation,the error compensation software based on the modified NC program are run on the VMC-850 vertical machining center of FANUC Series oi mate system.The results show that the machining ac-curacy after compensation is improved by about 30%.
