A numerical control machine tool comprises a rotary table, the rotary table is connected to a translation shaft, the rotary table can move along the translation shaft, and the rotary table can rotate around the axis of the rotary table. According to the method, a laser tracker or a multi-view camera is used, a target is fixed to the rotary table of the machine tool, and the rotary table moves according to a set program; the instrument tracks and measures the coordinate value of the target, the turntable error can be obtained according to the coordinate data and the calculation formula provided by the invention, and the error of the machine tool turntable can be quickly and accurately measured. 数控机床转台误差快速测量方法，所述的数控机床含有转台，转台连接在一个平动轴上，转台可以沿平动轴运动，转台可以绕其本身的轴心转动，本方法使用激光跟踪仪或多目相机、通过将靶标固定于机床转台上，转台根据设定程序运动，仪器跟踪测量靶标坐标值，根据坐标数据和本发明提供的计算公式可获得转台误差，实现机床回转台误差的快速、准确测量。
