| 摘 要： | 对教材上的坐标旋转指令(G68)应用例题的程序进行仿真加工,结果发现与图纸要求的形状不相符,分析其原因是该指令没有坐标原点平移的功能。要正确使用该指令实现加工,可以先采用坐标原点平移,再旋转的方法;或采用先控制刀具运动到旋转中心,再执行旋转指令,旋转指令后的程序段都采用增量值编程的方法。对这两种方法进行编程和仿真加工,结果显示符合图纸要求。

| Abstract: | After the simulation machining of the program of the example applied in coordinate rotation com-mand （G68） in the text book ,it is discovered that the result is inconsistent with the shape required in the drawing .The reason is that there is no translation of the origin of coordinate in this order .In order to use it correctly ,two ways can be used ,translation of the origin of coordinate ,then revolving ;or controlling the tool moving to the rotating center ,then revolving .T he result of simulation machining is equal to the paper . |

| Keywords: | coordinate rotation command incremental value translation of the origin of coordinate simu-lation machining |
