目前五軸加工的規劃流程是先決定要用來加工的機臺，並設計適當的夾治具後才開始規劃刀具路徑。路徑規劃完成後必須於軟體中匯入機臺模型進行加工模擬，確認沒有任何問題方可進行實機加工。上述的規劃流程環環相扣，機臺模擬時若產生過行程或是干涉碰撞，則須重新調整夾治具、工件位置或刀具路徑，過程中仰賴工程師的經驗以試誤法調整直到解決問題。此外，若依傳統流程先設計夾治具，將會限制刀具路徑的可能性，而刀具路徑會影響加工的動態表現、表面品質與刀具壽命。本研究的目的即提出一個新的多軸加工規劃流程，先規劃刀具路徑後，再以旋轉刀軸軸向後的各個三軸行程空間的交集計算出不產生過行程的初始夾持空間，接著再以刀具端外型計算與床臺端外型的干涉碰撞區域，最後計算初始夾持空間與干涉碰撞區域的差集，即可計算出不產生過行程與干涉碰撞的夾持空間。接下來以最短各軸移動距離及旋轉角度為目標，找到空間中最佳的工件夾持位置。根據本論文中的產業應用案例，可縮短10.15%的加工軸向移動距離，並減少8.77%的加工時間。確定了夾持位置後，再計算出不產生干涉碰撞的夾具可設計空間，並以第三方開發程式輸入CAD/CAM軟體中協助工程師設計夾治具。本研究利用數位化與視覺化的技術，將夾持空間與設計空間具體化，藉此減少經驗決策並縮短學習曲線，節省加工規劃的時間，以提升整體的作業效率。目前市面上的商業軟體並無類似功能，故此空間視覺化與最佳化程式對五軸加工業有實質的助益。

Traditionally in the multi-axis tool path programming process, the machine is selected at first. Next, engineer would design the proper fixture and jig for the workpiece. Then the tool path and tool vector are designed and generated. After that, the machine model is needed to import into CAD/CAM software to simulate the whole machining process, to ensure there is no over-travelling and collision problems. When the problems occur, we need to adjust few things to solve the problems, including the tool path, the workpiece setup position, and the design of fixture and jig. Each step is connected with one another during the programming process. The adjustment is a trial-and-error process relied on engineer’s experience. Besides, the possibility of tool path is limited by the design of fixture and jig. However, the tool path is connected to the machining dynamics, surface integrity and tool life. The objective of this research is to propose a new multi-axis tool path programming process. In addition, we develop a program to analyze the tool path and to create a visualized space for optimization and assistant. At first, the engineer plans the ideal tool path. Then the program can compute a visualized fixturing space without over-travelling and collision problems. Next, the optimal workpiece setup position is calculated to obtain the shortest axial distance. According to the case study, the axial distance can be reduced by 10.15% and the machining time can be reduced by 8.77%. After the setup position is selected, the program computes a visualized designable space for fixture and jig, to avoid the collision problem. The space is then imported into CAD/CAM software to assist the engineer. The research applied digitalization and visualization technique to realize the fixturing space and designable space, to reduce empirical decisions and to shorten the learning curve. Currently, the commercial CAD/CAM software does not have similar functions, so the space visualization and optimization program has substantial benefits for the five-axis processing industry.
