UG后处理怎样把相邻的多段圆弧转换成一个圆弧

wwwzyq2008

ug后处理怎样把相邻的多段圆弧转换成一个圆弧用UG的CAVITY加工一个规则圆柱时，刀路常有很多段圆弧组成。MASTERCAM也有这个问题，但它的后处理会把相邻的多段圆弧转换成一个圆弧；UG的MDFG也有这个功能，但我发现MDFG中预设的公差太大，处理出来的程序偏差多达0。04，加工出来的工件也非常不理想，表面象老鼠啃过一样。
2 B7 D7 f5 |# a3 ]请问各位高手，UG的MDFG中该项参数在哪？先谢啦。

楼上的，我也有你这个问题的！不过我要加工的零件有１２段圆弧和１２段曲线（２维），当走圆弧时希望Ｇ０２　　走直线时　　Ｇ１，可是ＵＧ的后处理做出的却是很乱的一些圆弧，和一些直线！
后来只好该为线形输出，就是程序中没有圆弧＠

7 q( a, A- F8 d2 [这个问题好象ＵＧ好象是做不了，不过也许后处理没有搞好，

应试是你的后处理没改好!把它在节点上打断了.
你可把后处理发到我的邮箱来,我来改下.

打开TCL文件.
1 Z) d( X. l5 v4 H; {找到这行set mom_kin_arc_output_mode                   "QUADRANT"
有这行前加#
如#     set mom_kin_arc_output_mode                   "QUADRANT"
