救人一命胜造七级浮屠

我是名刚出道的新手!第一次遇到问题!为什么我的UG4.0后处理文件的坐标零点和我设置的零点不一样呢!有的就行,有的就不行,是不是我在编程时有问题呢?!请大哥们指点迷经!

拿个具体的事例说明一下~~

上传文档说明！

请大哥们帮忙看看！为什么会这样呢！无论我是用什么方法都没用，现在给大哥们上传截图说明是我加工的区域，用的是型腔铣Ｄ１０的刀粗铣！后处理是三轴铣床，后处理后坐标零点就不是圆的中心了，而是ＵＧ自定的一个！
请老师们帮帮我！

由于不让发送长度太长的文字，所以在程序段中截取了一段后处理文件，这是后处理后为被修改得到的坐标值，与我截图上的坐标零点是不是差太远了，为什么呢？！

不是UG的问题，是你机床设定的问题吧，G54（加工坐标系）设的对吗？

和选择机床好象没太多的问题吧,主要是坐标不对,在UG模拟中的图片,应该也可以看到坐标都是正确的,一后处理后,得出的坐标就差很多,出现了UG自设的零点问题!我在圆心处设的零点根本不被采用!师傅们可以自己试着画一画,里面的圆直径是800,大圆直径是977.6,有8个均布宽18的台阶,台阶深度为4.07,台阶长度是11.2!按图片上的地方加工,后处理以后会是什么样子,请师傅们帮忙解答!

你用的是UG自带的后处理吧！
那是英制的！

上传一个，你先用用看，没怎么用过这个！但应该可以用，好像是以前在论坛上下的，自己用的在公司电脑里！

谢谢,师傅,问题解决了,正如您所说,我把后处理文件改成公制部件,就可以了!谢谢,万分感激,激动得要哭了!在这里我给您磕一个,咚~~~~~~!谢谢!
