如何处理生成的程序头！

我用MasterCAM来做程序但有很大的程序头，我想知道工厂是怎么用
自动编出来的程序的！是直接用还是有其他的方法

说清楚，什么样子的程序头。你需要什么样的。

粘一个pst文件和nc样本上来

nc的格式完全是由mastercam在后处理时所用的 .pst 文件来控制的

很简单，如FUNAC系统，在MASTERCAM9.0中，先打开MACM-MILL-POSTS，找到MPFAN.PST文件，用记事本打开它，并找到#Start of file for non-zero tool number              
      pcuttype
      toolchng = one  
      if ntools = one,
        [
        #skip single tool outputs, stagetool must be on
        stagetool = m_one  
        !next_tool
        ]
      "%", e
      *progno, e
      "(PROGRAM NAME - ", sprogname, ")", e
      "(DATE=DD-MM-YY - ", date, " TIME=HH:MM - ", time, ")", e
      pbld, n, *smetric, e        
      pbld, n, *sgcode, *sgplane, "G40", "G49", "G80", *sgabsinc, e
      sav_absinc = absinc        
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if mi1 <= one, #Work coordinate system
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;[
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;absinc = one

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;pfbld, n, "G92", *xh, *yh, *zh, e
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;absinc = sav_absinc
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;]
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;pcom_moveb

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;pindex
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if mi1 > one, absinc = zero
