摘　　要：螺距误差是影响数控机床定位精度的重要因素,也是验收和检测的重要指标.在分析螺距误差补偿原理的基础上,通过对VDF850型加工中心X轴进行螺距误差补偿,阐述了FANUC系统数控机床螺距误差补偿的方法:安装高精度位移检测装置;设定螺距误差补偿参数;编程序,记录并求值,形成螺距误差数据;将补偿值输入数控系统后重启.Pitch error is not only a big factor affecting the positioning accuracy of NC machines, but also one of the most important indicators for acceptance and test. Based on the analysis of pitch errors,compensation on the X axis for the VDF850 machining center, and compensation for FANUC NC machines, this study proposes that the installation of displacement detection device be extremely accurate, compensation parameters set proper,and programming recorded.
