UG后处理刀补的正确输出方法

前一段时间搞ug 刀补的多刀处理问题,蛮头疼的,看到一强人Yeager给了一个方法.

S" S% D$ y( R% : m

在Cutcom On里面增加一個Custom Command.,.填入"MOM_force once D",这个

方法可以解决D号的模态省略的问题

,即在分层刀路里第二层G41/G42后没有D号的问题. 佩服啊！

在fanuc 、mazak等机床上试验过，在fanuc系统上如果G41后没有D号，可以执

行前一个模态的有效的D号，在G40后如果没有撤销刀补的直线段，刀补撤销没有问题，

在G40这一句不产生移动，在下一句G1 x y 的语句执行

。如果将G41D1 单独列一行，可以对下一个坐标点进行补偿，但是补偿点的位置有

误

在mazak系统中：G41D1单独列一行的语句运行后，立即对前一个坐标点进行补偿，

G40也是如此，也就是说补的位置不是我们要补的位置。' ~; k. M$ n. a3 |: Q- q( e

做好刀补的方法：

总结：1.在Cutcom On里面增加一個Custom Command.,.填入"MOM_force once
