雖然目前許多控制器的功能都已十分強大,伺服響應所引起的切削誤差都能透過控制器的內建機能克服,但這些控制器動輒數十萬,是一筆龐大開支。 無論 Heidenhain 或 Fanuc 的控制器在處理轉角誤差的問題,都是利用轉角減速的理論,因此若從變更NC碼進給率,應同樣能達成這個目標。可使傳統數控工具機,不須高昂的設備更新費用,得到更好的應用。 本文將以雷射干涉儀、BallBar及KGM量測系統,建立工具機誤差補正參數資料庫,對加工程式作二次後處理,以達到改善切削精度的目的。 At present many controllers’ functions are quite powerful and the serve’s responses can cause the cutting inaccuracy that overcomes the functions inside through controllers. But these controllers’ expenses are more than 100,000. Therefore, it’s certainly too big cost. No matter Heidenhain or Fanuc’s controllers deal with questions of the corner’s inaccuracy that make use of the corner’s deceleration both. If we alter the NC code feedrate, we also can reach the target consequently. The traditional machines don’t need the high-priced equipment to update for getting better manipulation. This text will examine the system with laser interferometer, BallBar and KGM systems, will set up Machining Center error and add and correct the parameter database, Second times to the post, in order to achieve the goal of improving the precision of cutting.
