测量方法是从7个任意位置分别进行一次原点复归，测定其停止位置，以读出的最大差值作为原点复归精度。

  应当指出，现有定位精度的检测是在快速、定位的情况下测量的，对某些进给系统风度不太好的数控机床，采用不同进给速度定位时，会得到不同的定位精度值。另外，定位精度的测定结果与环境温度和该坐标轴的工作状态有关，目前大部分数控机床采用半闭环系统，位置检测元件大多安装在驱动电动机上，在1m行程内产生0.01~0.02mm的误差是不奇怪的。这是热伸长产生的误差，有些机床便采用预拉伸(预紧)的方法来减少影响。

  每个坐标轴的重复定位精度是反映该轴的最基本精度指标，它反映了该轴运动精度的稳定性，不能设想精度差的机床能稳定地用于生产。目前，由于数控系统功能越来越多，对每个坐喷射器标运动精度的系统误差如螺距积累误差、反向间隙误差等都可以进行系统补偿，只有随机误差没法补偿，而重复定位精度正是反映了进给驱动机构的综合随机误差，它无法用数控系统补偿来修正，当发现它超差时，只有对进给传动链进行精调修正。因此，如果允许对机床进行选择，则应选择重复定位精度高的机床为好。
