【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:  
  
From MDF Post:

This is from the old postprocessor

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...
