标题: 【求助】后置处理Nurbs插补？
请教各位大侠，
现在的很多的数控系统都有样条插补功能，
可是传统的后置处理器输出的数控程序都是直线和圆弧逼近的，
这样数控程序很大，
而Nurbs输出的数控程序很少，
有没有人知道这样的后置处理怎样编制？？？
谁有做好的后置处理有这样的处理过程？？？
传一个好吗？？？？？？

这个问题我早就提过了，关键是后处理，但是怎么修改，我的haidenhain的，至今没有一个人回答我。

我到现在都没有弄明白Nurbs插补中各个数据的数学意义。包括cls文件中的以及G代码文件中的。
如果您能够给我说明白，我会马上给你做好一个后处理程序作为补偿。呵呵

ＮＵＲＢＳ插补，１，需要机床的支持。（需要机床的联动性能跟上，目前的一些普通的机台皆无法达到这种要求。）
２。需要后置处理的支持。
３。需要在机床控制中选择nurbs输出.

可以发一段程序给我看看吗？有可能可以帮到你

这是程序的链接https://www.icax.org/viewthread. ... 3D1&page=1#pid=&h=1&bpg=7&age=0

在此基础上增加一个机床很容易

好呀!
给大家只是讲UG中的,具体机床上需按具体机床了

UG后置中如何处理NURBS信息，请指教

作者: tk_cad 时间: 2004-9-1 11:45
在操作里的machine----motion output选中nurbs,在后处理中加入Nurbs的模块就行了,NC中会出现G6.2代码.

G6.2代码是FANUC控制器的
还有西门子的呢~~

作者: zhangshu80 时间: 2004-9-11 10:56
我也不知道啊!DING

作者: qinling 时间: 2004-9-23 15:04
这是本人用自己的后处理所处理出来的代码中的一段，与大家共同探讨。

K是什么意思?权重吗?
K1.000 后怎么什么都没有?

作者: qinling 时间: 2004-9-24 08:09
k是节点

作者: lwj-zy 时间: 2004-9-24 14:53
这个要顶！！！
我只把machine----motion output选中nurbs，处理出来的不行！！！
后处理中加入Nurbs的模块，就不明白了，

作者: qinling 时间: 2004-9-24 15:27
对于NURBS插补，除后处理外，最主要的是机床支持，现在有的机床支持SUPER_NURBS，而且输入的代码为线性插补，机床自动转换。UG18带有NURBS后处理方式，NX没有了，但ug18生成的nurbs程序不是很好，各位可自己做一下比较，大家可以做自己的后处理器，灵活而且速度快

作者: sang 时间: 2004-9-24 15:44
只有高速机支持ＮＵＲＢＳ插补。

请问在UG后处理中如何写NURBS后处理文件！

作者: las1109 时间: 2004-10-16 09:33
UG使用postbuilder 可以生成NURBS程序，用mdfg就不行.
另外问一个问题，有没有兄弟对FIDIA的NURBS了解比较透彻的？
