高速搪孔刀組合系統在製造業中很常見。分析與最佳化是設計過程中的重要步驟。 因此，本論文的目的是針對高速搪孔刀組合系統進行分析和最佳化。
第一部分，將使用 ANSYS Workbench 與 RecurDyn 軟體針對此系統進行靜態分析以及模態分析。 這允許預測系統的變形、應力以及應變分佈。 還獲得了自然頻率與振型。 這些發現有助於判斷高速搪孔刀組合系統的設計有效性。
第二部分，經由RecurDyn/AutoDesign 針對高速搪孔刀組合系統的組件進行最佳化。 已為刀柄與動態吸振器 (Dynamic Vibration Absorb) 建立外型最佳化程序。 ProcessNet 也被納入最佳化過程，以幫助設置其他參數作為分析響應 (Analysis Response)，例如質量，第一自然頻率或變形量。 根據最佳化結果，選出最適合設計要求的最佳解。
作為本論文的結果：已得到高速搪孔刀組合系統的變形與應力； 得到並描述前六個振型， 前六個自然頻率/模態振型以及兩個軟體(ANSYS與RecurDyn)結果的比對。 最後針對四種不同目標最佳化情況，找出刀柄與動態吸振器的最佳化設計。

High Speed Boring Cutter Combination System is common in manufacturing. Analysis and Optimization are important steps in the design process. Therefore, the purpose of this thesis is to analyze and optimize the High Boring Cutter Combination System
First, Static and modal analysis of the system will be carried out using ANSYS Workbench and RecurDyn software. This allowed for the prediction of the system's deformation, stress, and strain distribution. Also obtained were natural frequency and mode shapes. These findings assist in judging the combination boring cutter system's design effectiveness.
Second, RecurDyn/AutoDesign was used to optimize the components of the boring cutter combination system. The optimization procedure has been built to optimize the shape of the taper shank and the shape of the DVA(Dynamic Vibration Absorb) block included in the damped boring bar. ProcessNet was also incorporated into the optimization process to help set additional parameters as Analysis Responses, such as the mass, first natural frequency or deformation. Based on the optimization results, the most optimized set for design requirements can be selected.
As the results of this research, the total deformation and equivalent stress of the boring cutter system are discovered; the first six mode shapes and the first six natural frequencies / mode shapes are found and described by using ANSYS Workbench software as well as RecurDyn software. Finally, the optimal design of the taper shank and damped boring bar was found for four different objective cases of optimization.
