【讨论】淺談GPost(SPost)一些特殊應用

我們常常需要輸出一些特殊的G或M代碼...
有時候用MPostwin, Lpostwin...不是很好處理..是必須要用到GPost(SPost),甚至於要寫FIL..
  
其實,後處理就是一個翻譯 走刀路逕 成為 NC代碼程序 的翻譯器.. 而我們定製的機器配置文件 就是一個 翻譯的表單 字彙的集合文件..
  
每一套CAM所輸出的APT CL大部分是相似的...但是還是有一些特殊的PP Words(所謂的後處理詞彙, 字彙)是不同的
  
例如:
雖然SURFCAM與Pro-NC 都是用GPost(SPost), 但是兩各系統所輸出的APT不盡相同..
  
所以, 有些我寫的UNCX01.Pxx與UNCX01.Fxx 放到Pro-NC的系統, 不見得可以像在Surfcam系統裡, 完全轉譯輸出所要的NC代碼程序..

舉個例子來說吧..
比如說激光加工..
某激光加工機, 激光開啟:M04, 激光關閉:M05
  
激光加工 在每一段加工路逕實際開始時要有M04, 該段實際加工路逕結束要有M05 關閉激光
  
因此, 我們必須找出CAM輸出的每一段加工路逕實際開始時的APT語句, 每一段實際加工路逕結束時的APT語句..寫FIL 來讓GPost於適當的位置輸出 M04 與 M05

到 Surfcam\postlib\spost\下面有個Surfcam.vtb檔案..
用文本編輯器打開它..

那些3xxx數值大部分就是我們使用Surfcam與GPost時定義的一些PP Word位址號
例如:
PPWORD/ROW,3106  
我最常拿來使用..輸出激光開與關的代碼,我也用它
  
PPWORD/OPERTN,3111
寫車銑後處理, Surfcam輸出的APT裡就定義了何種類型的加工方式..我抓取那些定義的數值判斷 是 車 或 銑 等等 來輸出代碼..

相信Pro-NC某個目錄下面 應該也有類似的 PPword的字彙檔案 xxxxxx.vtb才對

Surfcam要怎樣才能輸出Row/Start與Row/End於APT裡呢?
  
在Opreation Manager裡選APT-CL
  
Post

會跳出一個參數盒...勾選 -B

選OK以後..產生出來的APT

PRO-NC是使用
PIERCE / ON 與 PIERCE / OFF  可以用來判別輸出 M04 與 M05

如果我在Surfcam裡使用GPost與所寫的機器配置文件..
我必須
改FIL裡的PPWord Row/Start 成 PIERCE / ON, Row/End 成PIERCE / OFF
  
另外, 在Surfcam.vtb加一項
  
PPWORD/PIERCE,3168 <------此數值不要重複到就可以
