    Abstract: 車銑複合工具機在工具機產業扮演著重要角色,具備複雜作動特性,以此特色,經常被應用來加工複雜零組件,以因應汽車、航太、醫療產業的加工產品複雜多樣化趨勢以及客製化的需求。走心式車銑複合機應用在連續生產精密的小型零件,其特色為具有多軸向以及雙系統。即便機台本身能讓加工效能提升,但操作機台的過程複雜且容易發生刀具與工件產生干涉,導致訓練新進人員時,學習時間曲線拉長,間接造成製造產業之技術人員的人力資源因資深工程師經驗不易傳承,造成技術銜接上,有斷層的現象發生。使用者如何在購買刀具後,測試合適的切削參數,大多是依靠資深工程師的加工經驗,結合刀具商手冊建議條件,逐一嘗試,需耗費不少的時間以及材料,才有可能嘗試出一組合適切削條件。但假如切削效能要提升就會因沒有測試時的條件依據而受到侷限。而要產生加工程式,工程師大多仰賴CAD/CAM軟體來進行工藝設計,其中在加工條件設定的環節,同樣需要仰賴CAD/CAM工程師經驗才能完成加工參數的設定,這也是一種造成技術傳承不易的情況。為此,本研究針對這些問題,將利用CUTPRO?軟體,結合資深工程師的加工經驗,以及執行一系列的實驗,建立一個具有顫振迴避觀念的切削參數優化建議流程,並將其模組化與實際進行切削驗證,提供使用者一套科學化的加工參數設定依據;同時利用Visual Studio 2013 C#與OpenGL為基礎的API建構虛擬3D工具機及實體切削模擬模組,並整合互動式虛擬人機介面,使用者透過操作互動式虛擬人機介面與虛擬3D工具機進行互動,協助使用者快速了解工具機的作動情形,藉以將資深工程師的經驗可視化以及科學化,建立一套走心車銑複合機教育訓練以及切削參數優化建議系統。
    Mill-turn machine plays an important role in the machine tool industry, which has complex actuation characteristics and is often used to process complex components. In response to the complex diversification of processing products in the automotive, aerospace and medical industries, and the demand for customization.Swiss-Type mill-turn machines, which are capable of multi-axis machining and controlling two independent system, are widely used in machining lots of small precision parts in turn-mill machines. However, due to the complex operations and high risk of tool-workpiece collisions, learning curve of Swiss-Type mill-turn operations is comparatively very long. Indirectly, the experience of senior engineers is very difficult to pass down, resulting in the phenomenon of technical inheritance.How can we test the appropriate cutting parameters after purchasing the tool? In general, it depends on the experience of senior engineers, combined with the suggestions of the tool manufacturer manual. It takes a lot of time and cost of materials through trial-and-error one by one. And eventually on only can get a set of cutting parameter. If one want to enhance performance of the manufacture, it will be limited. In order to produce the NC program, the engineering type mostly relies on the CAD/CAM software for process design. In the process of setting the processing conditions, it is also necessary to rely on the experience of CAD/CAM engineer to complete the setting of the processing parameters, which might also become a technical inheritance gap.In order to solve these problems, this research adopted CUTPRO? software, combined with the experience of experienced engineers, and a series of experiments to establish a cutting parameter optimization suggestion process with chatter avoidance. Real cutting experiment was conduct for the verification to provide users with a set of scientific processing parameters setting basis. At the same time, the research use Visual Studio 2013 C# and OpenGL-based API to construct virtual 3D machine tool, cutting simulation, and integrate interactive virtual human-machine interface. An interactive virtual human-machine interface has been developed to interact with the virtual 3D machine tool to help users quickly understand the working conditions of the machine tool. The experience of senior engineers can the be visualized scientifically, and a Swiss-Type mill-turn machine education training and cutting parameter optimization suggestion system has been successfully established.
