【注意】关于ugnx1和ugnx2，ijk和r输出圆弧在fanuc……？

请将附件下载后在机床上空走试一下（要有graphic功能）。
特别注意标明有问题的指令。
除了用UGNX1和ugnx2，ijk变成r外，其他的参数在ugpost中是一样的。
有人碰到过这样的问题吗？
谢谢大家！

有人试验过吗？
我想知道是不是因为ugnx1的ugpost本身有问题？

在fauuc om控制器上i j會走一個圓弧過切　深受其害

那是因为你的后处理没做好，IJK要做为非模态指令

老大：不知道你看过程序没有（标出有问题的地方是不正确的指令，没有标有问题的地方是相同的位置用不同的后处理器（r或ijk生成的），跟ijk是否模态没关系（我已经实验过了）。你把程序上机床走走就知道了。
谢谢…………………………………………！

用nx1后处理，走圆用r，打断，正常
