現代齒輪專用量測機為四軸結構，配備接觸式掃描探頭系統，有很高的量測精度。然而接觸式量測面臨幾個問題，主要有(1)量測需要比較長的時間，很難縮短工作時程，以及(2)直徑過小的探頭(小於1mm)容易斷裂，故量測小模數齒輪有所限制，因此非接觸式掃描量測成為近年研究的主要課題。
本論文主要致力於建立圓柱齒輪的線雷射輪廓感測器非接觸式掃描量測系統，利用五軸工具機上的西門子840Dsl控制器和線雷射感測器的組合規劃量測路徑，並藉由以Visual C#開發的程式計算量測路徑和圓柱齒輪精度評估。
本論文在五軸機上發展四軸量測機之線雷射掃描量測系統，建立圓柱齒輪的量測數學模式及其精度評估。根據圓柱齒輪的理論齒形可計算出線雷射感測器的量測位置，輪廓資料點(每條線有3200點)將從線雷射控制器透過乙太網路傳輸至個人電腦並建構量測齒面，而B-Spline曲線適合對量測資料點進行擬合，以建立評估齒輪精度的數學模式。實驗結果將與Klingelnberg P40齒輪量測專用機檢測報告比對，以驗證數學模式的正確性。

The modern four-axis gear measuring machine has a contact scanning probe system with high measurement accuracy. However, the contact measurement has several problems. The main ones are (1) the measurement takes a long time, it is difficult to shorten the processing time, and (2) if the diameter of the probe is too small (diameter less than 1mm) is easy to damage, so the measurement of small-sized gears is limited. Therefore, the non-contact scanning measurement gets more attention in recent years.
This research mainly focuses on establishing the line non-contact scanning measurement system of cylindrical gears using the line laser profiler. The measurement path is planned using the combination of the Siemens 840Dsl controller and the line laser sensor on a five-axis machine tool. The program developed by the Visual C# calculates the measurement positions and evaluates the cylindrical gears' accuracy.
This research develops the four-axis line laser scanning measurement system on the five-axis machine tool. The mathematical model of the cylindrical gear measurement and its accuracy evaluation is established. The measurement positions of the line laser profiler are calculated depended on the theoretical tooth profile of the cylindrical gear. The profile data points (each line has 3200 points) will be transmitted to the personal computer through an Ethernet network from the line laser sensor controller and construct the measured tooth surface. Here, the B-Spline curve is adapted to fit the measured data points to establish the mathematical model for evaluating the gear accuracy. The experimental results will be compared with the Klingelnberg P40 gear measuring machine inspection report to verify the mathematical model's correctness.
