三軸工具機之活化與教導式銑削系統開發

在機械工業中，工具機佔有不可取代的重要地位，然而隨著自動化工業不斷的發展，對於數控工具機的需求也與日俱增，因此對於數控工具機的人材培訓更是國家永續發展的重要一環。本文可分成兩個部份，分別是活化三軸綜合切削中心機與開發一套教導式銑削加工系統(E-cutting system)。活化三軸綜合切削中心機是搭載智研PC-Based控制器M450S並介紹工具機之組成元件及作動原理，而RENISHAW公司的雷射干涉儀XL-80是用於量測補正誤差，將軸向誤差補正於10μm內，最後再以PC-Based開放式的架構建構出自動換刀系統的順序控制及人機介面。教導式銑削加工系統主要是以三軸工具機為基礎，以2.5D層銑削加工方式建立其教導式銑削加工系統，將可有效率地設定刀具參數與加工參數，並利用圖控元件與步驟式的設定方式，能快速產生一組具備最適化的NC加工路徑，如此可減少程式編寫的時間與人為編寫NC程式上的疏失。

Milling occupies an important position in the machinery industry. The demand of CNC machine tools is also increasing due to the continuous development of the automatic industry.Therefore,thehigh-level manpower training of CNC machine tools is a very important issue for sustainable development of a nation. This paper is to reconstruct a3-axis CNCmachinetool and develop a tutorial form milling system (E-cutting system). Amachine tool is equipped with the INTEK PC-based controller M450S.The main components of the mechatronic system and the actuation principlesof machine toolsareintroduced in this thesis.The RENISHAW XL-80 laser interferometer is utilized formeasuringthe amount of backlash and pitch error for compensation purpose.The positioning error of each axiscan be controlled within 10μm, then the sequence control and humanmachine interfaceof an automatic tool changer is designed by the open architecture.E-cutting system adopts 2.5D layer millingto build up its tutorialmilling system that can set tool parameters and processing parameters efficiently.End users employ the icons and step by step methodto generate the optimal NC machining path. Thus, the faults of NC programming and coding time can be reduced.
