臺灣博碩士論文加值系統

影響工具機的加工精度與品質不外乎機台的使用狀況以及切削條件合適與否，目前進行工具機切削量測由於工具機本身的機構剛性及製造的限制，切削中不可避免高溫的因素造成工件、機台受力的變形、刀具磨耗等因素，為了避免上述因素的影響，監控實際切削狀態顯得極為重要。
本研究開發一套無線藍芽傳輸多功感測模組，應用於五軸工具機(百德機械﹐MF400U)並架設溫度感測器於工具機主軸進行熱溫升量測，藉由K60最小開發版接收溫度訊號，以無線藍芽模組傳輸溫度資料，而刀具的熱變形量測量係使用接觸式刀具測量器波龍(Blum) Z-3D以量測刀具的長度與半徑。
可從主軸無切削負載運轉與實際切削加工時量測到的數據，獲得溫度變化量、刀具長度與其半徑變化量，以及刀具每次切削前後的磨耗量，可應用於後續熱溫升補償。

The factors that affect the machining accuracy and quality of the machine tool are nothing more than the usage of the machine and the appropriate cutting conditions. When a machine tool is utilized for cutting operation, the high temperature generated during machining will cause the overall temperature rising of the machine tool, resulting from thermal deformation of the workpiece, machine, and tool. In order to control the effects of the above conditions, it is extremely important to monitor the actual cutting state.
In this research, a wireless Bluetooth transmission multi-function sensing module is developed for thermal-shifting measurement of a five-axis machine tool. The temperature sensor was installed on the spindle of the machine tool for thermal temperature rise measurement. The K60 minimum development version was used to receive the temperature signal and transmits the temperature data via a wireless Bluetooth module. The effect of the thermal deformation of the tool on its length and radius was measured using the contact tool gauge Blum Z-3D.
From the data measured during actual machining, we can obtain the amount of temperature change, the elongation and the radial deformation of the tool, and the amount of wear before and after each cutting of the tool. These data can be applied to the subsequent spindle thermal drift compensation.
