数控机床的单一方向定位功能也称精密定位功能，一般简称单向定位。指数控坐标轴以预先设定的一个方向完成定位，定位方向与运动方向无关，在准备功能中用Ｇ６０表示。１ 单向定位的执行过程 如图所示，如果在从Ａ点向Ｂ点定位的程序段中指令了Ｇ６０，ＣＮＣ先判别设定的
The single-directional positioning function of CNC machine tools, also known as precision positioning function, generally referred to as one-way positioning. It refers to the coordinate axis that is set in a preset direction. The positioning direction is independent of the direction of movement. It is indicated by G60 in the preparation function. 1 The execution of one-way positioning is as shown in the figure. If G60 is commanded in a block that is positioned from point A to point B, the CNC first checks the set
