是的，和我的一样，就是有误差，照理像做这种凸轮Y、Z是不应该动的，PROE就不能把轴锁定，我试过把刀具直径设置的越大，那Y、Z的移动数据就会越大，是不是？想问一下，你是不是也经常做四轴加工，用的是什么机床？

2. Pro/E不會有誤差的,只要你使用的機器支援4軸同動就ok啦
  
3. 我平時用5軸的機器,有時候用5軸的機器做4軸的動作

呵呵...老兄是Mcad_cafe

我也有误差,怎么回事?求教.

Mcad_cafe 的站長是我的好朋友, 他現在正忙著寫論文, 有空大家網聚認識認識

五轴的很少啊，不知道仁兄是那里的？

楼上的程序行吗?

为什么我这里出现警告,STEP_OVER比切削半径大的警告内?
很不明白,,,
