螺桿轉子壓縮機由公轉子和母轉子組成，通常在銑削中用於粗加工和磨削用於精加工。帶刀片的刀具適用於螺桿轉子銑削。由於幾何輪廓獨特，每個螺桿轉子輪廓都需要獨特的銑刀設計。需要穩健的刀具設計，包括刀體上的刀片，因為它顯著影響加工精度。因此，研究使用帶有多個刀片（標准或特殊刀片）的盤式銑刀進行銑削操作的螺桿轉子切削是必不可少的。本研究提出了刀片位置確定方法和刀具設計優化模型的解析設計。此外，研究了一種通過刀片切削軌跡法快速獲取模擬轉子輪廓和切削痕的預測模型。這項研究是通過研究螺桿轉子加工的基本概念，包括轉子幾何輪廓和銑刀特性，以一般方法完成的。分析模型包括改進的刀具坯料和刀體輪廓生成方法、刀片安裝到刀體上的新方法、CNC機床模型上的螺桿轉子切削、快速生成模擬轉子輪廓和切削痕的ICT方法以及計算方法通過推導數學方程和程序源代碼建立了轉子輪廓評估。隨後，通過執行螺桿轉子切削模擬（包括 Vericut 軟件的虛擬加工）來檢驗分析模型，並根據理論設計評估模擬結果。最後，進行了實驗測試，以驗證分析設計和模擬結果。結果表明，所有提出的分析模型都是可靠且完全可行的，因為它們成功地達到了它們的目的和功能。;Screw rotor compressor consists of male and female rotors commonly manufactured in milling for roughing and grinding for finishing. A cutter with inserts is suitably applied in screw rotor milling. Since the geometry profile is unique, each screw rotor profile requires a distinct milling cutter design. A robust cutter design, including the inserts onto the cutter body, is required since it significantly influences the machining precision. Hence, a study on screw rotor cutting by milling operation using a disk-type milling cutter with multiple inserts, either standard or special, is essential. This study proposes an analytical design for the insert position establishment method and cutter design optimization model. In addition, a prediction model for rapidly acquiring a simulated rotor profile and cutting marks by the insert cutting trajectory method is studied. The research was accomplished in a general approach by studying the basic concepts of the screw rotor machining, including the rotor geometry profile and milling cutter characteristics. The analytical model consisting of a modified method for generating cutter stock and body profiles, a novel method for inserts establishment onto cutter body, screw rotor cutting on CNC machine model, ICT method for rapidly generating simulated rotor profile and cutting marks, and calculation method for rotor profile evaluation by deriving mathematical equations and the program source codes were established. Subsequently, the analytical models were examined by performing the screw rotor cutting simulation, including the virtual machining by Vericut software, and evaluating the simulated result according to the theoretical design. Finally, an experimental test was conducted to verify the analytical design and simulated results. The results indicate that all the proposed analytical models are reliable and entirely practicable since they successfully reach their purposes and functions.
