虛擬實境技術被廣泛應用在不同領域，包括半導體、航太、汽車等產業。利用虛擬多軸工具機能提供產品製造過程的加工驗證，評估其可製造性。
使用商用虛擬實境軟體來建構虛擬多軸工具機有擴充上的限制，函式庫並不能滿足開發者的需求。本文為了發展自身所需的函式庫功能，因此將使用OpenGL的3D繪圖函式庫作為開發虛擬環境的工具。另一方面，對於五軸虛擬工具機的一般化建構流程，利用D-H修正標記法表達工具機各軸之相對位置與運動方向，且在組裝虛擬工具機時，對各桿件上的座標系定義出符合D-H修正標記法的座標系統，使用者只需在決定工具機構型後，系統將自動判斷各軸桿件之間的座標定義，經由輸入桿件模型等程序，就能迅速精準的建構各種構型之五軸虛擬工具機。
本文以視窗程式為架構，使用OpenGL作為視窗顯示畫面。使用者以操作介面可選擇構型並組裝五軸虛擬工具機。最後以一五軸虛擬工具機對於葉片加工之工業實例呈現虛擬工具機組裝過程與模擬葉片切削時之工具機運動，並以VERICUT模擬軟體進行驗證比對。

Virtual reality technology has been applied to various industries, such as semiconductor, aerospace and automobile. A virtual multi-axis machine tool can be used to verify the machining process and evaluate manufacturability.
The virtual multi-axis machine tool based on commercial software has limitations to expand. Because the functions of library cannot meet the demands of the developer, the objective of this thesis is to develop virtual environment based on OpneGL library. Modified D-H notation is used to represent the relative position and motion direction of machine tool axes for universal assembly of five-axis virtual machine tool. In the assembly process, the system will assign the coordinate frames of machine tool axes according to Modified D-H notation. This can assist users assembling the five-axis virtual machine tool efficiently and effectively.
In this thesis, user interface is developed and the system display is based on OpenGL. With the interface, users can select configuration and assemble virtual machine tool. Finally, a five-axis machine tool was taken as an example to perform the assembly and simulate the machine tool motion. The motion simulation of machining an industrial blade was verified by VERICUT software.
