标题: 【讨论】FANUC 机床报警, 后处理讨论
相同加工, 分别用旧的MDF后处理机和UG/POST处理, 结果不大一样, 新的后置多出两条圆弧插补, 导致机床报警, "Over tolerance of radius", 程序片段如下:

This is from the old postprocessor

作者: jinly 时间: 2004-1-7 09:56
this is from New Postprocessor

This is the MDFA file for old postprocessor

This is the new FANUC postprocessor

What is the reason for this error warning ?

   I asked some friends, with many different reasons......Anyway, how can I solve this problem as soon as possible?

    各位大侠, 多谢帮忙!!!

两种运算公差，好像::?

我研究发现一点: 在MDFA的GPM模块可以将CLSF中相同圆心和半径的几段圆弧插补合并成一段. 但是在TCL文件中没有..

..上面的几段圆弧插补有相同的圆心和半径.....

这里是不是有点问题? 我在TCL文件中加入一段去合并圆弧, 可是其他一些圆弧也被合并了....这里面如何控制, 我还不懂问题的关键在哪里?

请指教, 我现在连方向都搞不清了, 只想按表面现象来搞, 就是把多出的几条圆合并, 但是可能带来其它很多问题.

  关键可能还是在公差问题, 可是我改来改去, 就是不能解决问题.

对了, 忘了零件:

    啊?! 零件太大?!........老大.....加点分啊...

sorry , i can't help you. but according the warning message is the tolerance
you could check you set the arc tolerance! give you my wish!
