    • 自十八世紀工業革命以來，提升生產力一直是工業界創新的重點。 現階段已發展至工業 4.0 也就是在工業生產及製程上，加上物聯網以及智慧型整合感控系統， 能夠運用大數據及雲端的方法，使工具機能夠達到高度自動化，自動排除生產障礙，提升生產效率。 而台灣也在國際化的驅使下，跟進工業 4.0的腳步。在現今產線需求增加，工具機能否正常運作變得格外重要。 為了能夠提升工具機的加工精度以及正常運作 ，仰賴監控系統的 輔助 本論文利用實驗方法，監控工具機流道的流阻變化以及溫升趨勢。 使用相似性的方法建立一套循環流道 ，模擬工具機主軸內部的循環 流道，並且加裝壓力計以及流量計監控流阻變化，蒐集異常狀況並分析。 同時使用漆包線纏繞於我們所建立之 循環流道，模擬主軸因軸承以 及線圈產生的熱量，並在流道表面黏貼熱電偶，觀察流道溫度分布情形。同時，我們也利用 ANSYS進行管壁溫度分布的模擬， 並將結果 與實際業界參考指標做比較，分析 流道管壁溫度與流體 溫度之關係，判斷是否經由監控進出口水溫差，即可反映出流道管壁 溫度分布的均勻性。

    Since the industrial revolution in the eighteenth century, upgrading productivity has been the focus of innovation in industry. At this stage, it has been developed to Industrial 4.0, that is, we can combine the cyber physical system and intelligent integrated sensory control system with industrial production and manufacturing, which can use the big data and cloud to make the machine tool highly automated and automatically eliminate production obstacles. In order to improve the machining accuracy and normal operation of the machine tool, we must rely on the monitoring system. Therefore, this thesis uses the experimental method to monitor the flow resistance and temperature rise of spindle coolant. A similarity method is used to establish the cooling channel, to simulate the cooling channel inside the spindle of the machine tool. Moreover, we install a pressure gauge and a flow meter to monitor the flow resistance change, in order to monitor working conditions and analyze. At the same time, the enameled wire is wound around the circulating flow channel we established, simulating the heat generated by the bearing and the coil, and attaching the thermocouple on the surface of the flow channel to observe the temperature distribution of the flow channel. Meanwhile, we also use ANSYS to simulate the wall temperature distribution, and compare the results with the actual industry reference indicators to analyze the relationship between the wall temperature and the fluid temperature of the flow channel, and determine whether the uniformity of the temperature distribution of the pipe wall can be reflected by monitoring the inlet and outlet fluid temperature difference.
