UG后处理刀补的正确输出方法

1、UG后处理刀补的正确输出方法. w/ X; - J4 f* ; Q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！关于G40的处理:.

5、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.
