摘要: 
熱誤差一直是工具機精度誤差的主要來源,尤其當工具機朝向高速化發展後,由於高速化所伴隨之大量熱源使熱變形之變化將更為顯著。如何改善機台熱誤差日漸受到重視與研究。熱補償是一種將預估的補償值傳入控制器後進行補償動作以提高機台精度的方式,在熱補償的方式中常見的為修改加工指令、修改伺服控制迴路與外部原點漂移。本研究以外部原點漂移的方式,設計一即時熱誤差補償系統,最後實際應用於機台上,測試此系統之可用性。
本研究針對熱補償中補償系統與控制器之交握,以單晶片為主體,開發一套即時熱誤差補償系統,其中包含單晶片模組電路、溫度感測電路、LCD顯示電路及補償資料傳輸電路…等。I.C.型溫度感測器經由單晶片計算出溫度值後,再用補償模型計算出補償值,將各溫度值與補償值顯示於LCD面板,並以LED顯示補償值以及與控制器訊號傳送的做動情形,最後修改PMC的階梯圖程式,使CNC控制器啟動外部原點漂移功能對主軸進行補償動作,可補償範圍為0~255μm。

Thermal error has been a major source of precision errors in machine tool. Particularly, when machine tool towards high-speed development. Due to large heat source with high-speed make the thermal deformation more significant. How to improve the thermal error in machine tool increasing attention and research. Thermal compensation is a way to use estimated compensation value delivering to controller to conduct compensation to improve the accuracy of machine tool. Thermal compensation in the manner common to modify the processing instructions, modified servo control loop and external machine coordinate system shift. In this study, use external machine coordinate system shift to design a real-time thermal error compensation system. The final stage, actual Application to machine tool to test the system availability.
In this study, aim for connects with thermal compensation system and controller. The basis of single chip to build a real-time thermal error compensation system. The system contains single-chip module circuit, temperature sensor, LCD display circuit and compensation data transmission circuit ... etc. After Calculated IC Temperature Sensor temperature value by the single-chip, show the temperature value and compensation value on the LCD panel. Then use LED to show the compensation value and Action case with controller. Finally, modify the PMC ladder diagram programming, the CNC controller starts to external machine coordinate system shift of the spindle motion. Compensate for the range of 0 ~ 255μm.
