在N2560-N2570之间那行，U轴突然变化，这是为何？
我在后处理上给的U轴行程是-20-110，如果我改成0-110就不会出现了，

这是我的后处理，附上

這段刀路,以學理上來說,是沒有錯的!!!為何?????

因為机床的極限在U-20.當然輸出的刀軌不能越過這極限,因此后置將W轴反转,以對向的形式輸出!!!!

所以問題出在刀路的設計根本就是錯的,這机床無法完成這樣的動作,后置只是忠實的作转換而已!!!

在操做中家用户自定义控制LINTOL/ON就可以了

這是我加入Lintol之後的片段程序,似乎還沒有解決!!!
不知老師還有沒其他解法????

稍微该了一下没问题了,附件是NC程序
