    Abstract: 現今市面上用於量測工具機幾何誤差之系統其只能單次量測單一個自由度誤差,且量測所耗費的時間太長,因此本研究將設計一新型非接觸式光學式誤差量測系統,將用於量測工具機線性軸六自由度之誤差,與市售光學量測系統相比,此量測系統具有同時量測六自由度誤差,及低成本之優勢,期望此量測系統可提升台灣工具機於世界的競爭性。 本文所提出的新型量測系統結合雷射干涉儀與其定位鏡組、光學元件與位置感測器,並在誤差量測系統中加入雷射誤差擾動補償裝置,提高量測系統的準確性,在提高系統精度的同時,還能一次同時量測到六個自由度的誤差,期望能讓國內工具機業在國際上更具競爭力。在本論文中,我們將分別以定性與定量上的分析來對所提出之量測系統進行可行性驗證。首先在定性上的分析即是將所提出之系統架構建構於光學模擬軟體-ZEMAX來觀察其系統特性與趨勢,接著使用數學齊次座標轉換矩陣為所提出架構建立完善的數學模型,並以歪斜光線追蹤法來追蹤雷射光線在新型量測系統內之實際光線變化情況,即以數學推導的方式為本量測系統進行定量上之分析。完成定性與定量上分析之後,將所設計之新型量測系統實際架設於光學桌進行實驗,並將實際量測的結果與上述模擬和數學推導的結果進行數據分析與比對,並與現今市售量測系統雷射干涉儀比較,確立本量測架構之可行性。
    Today on the market, the geometric error measurement system of the machine tool, only can measure a single error, and it takes too much time, In this thesis, we will design a novel non-contact optical error measurement system for machine tool. Compared with the commercial optical measurement system, this measurement system has the advantage of measuring six degrees of freedom error simultaneously and low cost, and it is expected that this measurement system will enhance Taiwan's competitiveness.In this thesis, we will qualitatively and quantitatively analyze the feasibility of the proposed measurement system to verify. Firstly, the qualitative analysis is carried out, and the system characteristics and trends are observed by using the optical simulation software-ZEMAX. Then, the mathematic homogeneous coordinate transformation matrix is used to establish the perfect mathematical model, and the skew ray tracing method is used to track the laser In the new measurement system, the mathematical approach to the quantitative measurement system for quantitative analysis. After the qualitative and quantitative analysis is completed, the nonel measurement system is actually set up in the optical table to carry out the experiment, and the actual measurement results and the simulation and mathematical results of the data analysis and comparison, and with the city Comparison of the measurement system, the feasibility of this measurement architecture is established.
