五轴加工案例

pzcaa也帮我看看后处理，谢了！

烦请Yeager兄看看我的后处理，也帮忙批批，我觉得有问题，就在圆上走圆弧时后处理出来的程式多140多行，如果是按道理，十行就都不用的，所以我觉得后处理还是有问题，在此谢过了。

非也!!!
若是要有圆弧的輸出,必須在G17平面吧!!您的刀路,不可能出現G2/G3的......都是走點的!!

或者,您要的是:
U30.W0.
W90.
W180.
W270.
W360.

這種類型的刀路吧?!?!?那麼,PB默認是沒有的,必須用TCL寫一些filter,過濾掉多餘的刀軌!!

列出您要的結果看看!!!

SORRY,最近有点忙,等空的时候一定看,现在有POSTBULID  3.5版本了,自己在试试!!

我用的是3。0，PB是3。2。1版本的，跟3。5版本的有什么差别吗？请指教！

Yeager兄，下面的程式是我用Mastercam做的程式，后处理已确认过的，程式可以确认是没问题，但我用UG做跟这个有很大的差别了。先附上MS做的。。

我用的是3。0，PB是3。2。1版本的，跟3。5版本的有什么差别吗？请指教！

PB的版次跟UG沒直接関係,我現在也是用NX3,但PB我就用3.5版的!!

差異在哪????一言難盡啊.........

Yeager兄，下面的程式是我用Mastercam做的程式，后处理已确认过的，程式可以确认是没问题，但我用UG做跟这个有很大的差别了。先附上MS做的。。

1.看您在PB內的設定,U轴的範圍在-20~+110間,所以U的輸出不可能有MCAM中-44....的情形的;但您又說MCAM的結果是正确的!!!!故,再确认ㄧ下机床的極限吧!!

2.U轴的角度值,都在-44.43~-44.0間反覆変化,确定這是您要的結果?????個人直覺,應該是程式設定的問題,跟后置無関!!依您的圖檔,ㄧ個正圓的圖形,刀轴又是normal to part,不應該會出現U轴一直変化的狀況,這點也要确认!!

那我的3。0装上去PB就是3。2。1版的，怎样才可以得到3。5版本的？

在这里我没跟你特别说明，我们机床老式五轴机（现在全量有新式五轴机推出市场了）的结构是U轴尽量在正方向运动，U轴最大可以达到-45，但很少去用，因为能用正方向的就尽量用正方向（明天我可以拍张结构图给你），正方向的精度太差，今天把程式放在机床上空跑了一下，基本上都行，但是还有一个问题就是我在一个50MM的半圆上走螺旋时，U轴首先在负方向-20运动，但是在一个单节突然变为正方向+20运动，我想这样工件肯定被干了/。/。。。。/帮忙！

Yeager兄这就是我们U,W的结构/
