摘要

近年來，為提升五軸CNC工具機之加工精度，多種研究提升精度之方式中，如何檢測工具機誤差並提高機台精度是一項重要課題，本文使用計畫開發之光學式五軸CNC檢測系統－NON-BAR，在原檢測程式中發現以下問題：(1)增益值校正不同步(2)檢測軸心偏移之準確性(3)手動取樣誤差(4)數據判讀不便(5)操作步驟繁瑣。
為改善上述問題，本文遵循ISO/CD 10791-6之檢測路徑與規範，以分頁介面設計程式，包含：(1)增益值同步校正：整合動靜態檢測，同步校正增益值；(2)靜態檢測誤差：根據ISO R1101規範-最小區域圓法(Minimum Zone Circle，MZC)，計算精確軸心偏移量；(3)連結設定：與控制器連結，自動取樣減少手動執行誤差；(4)動態檢測誤差：增加資料繪圖直接判斷數據趨勢；(5)背隙補償：與HEIDENHAIN(iTNC-530)或FANUC(18i)控制器連結，自動檢測與補償背隙誤差及(6)熱溫升檢測：檢測工具機在長時間運作因溫度變化造成數據偏移趨勢。
重新開發設計之程式介面除了能夠更人性化操作，且經過檢測與補償結果，線性軸背隙可補償至1μm以下，旋轉軸背隙可補償至0.001°以下，軸心偏移量可降至10μm以下。

The manufacturing technology of the five-axis CNC machine tools has progressed in recent year. And how to measure the error for improving the accuracy of the five-axis CNC machine tool become an important task. The original interface of the developed NON-BAR has some problems as following:(1)different of the gain value;(2)accuracy of the axial error; (3)sampling error by manual;(4)inconvenience to analysis the measurement result, and (5)complicated operation steps.
In order to improve those problems, this follows the ISO/CD 10791-6 for design the interface with diffident program pages as following:(1)setup for the gain value: integration of the dynamic and static detection to setup the gain value simultaneously;(2)static detection: according to the Minimum Zone Circle (MZC) of ISO R1101, the axial error can be calculated accurately;(3)setup for the link: to link with controller for auto-sampling and reduce the sampling error by manual;(4)dynamic detection: to add directly analysis function within data drawing program;(5)backlash detection: to link with HEIDENHAIN(iTNC-530) controller or FANUC(18i) controller for auto-measuring and compensating backlash error, and(6)temperature detection: to measure the error trend due to temperature changes for a long time of the machine tool.

In this thesis the operation of the novel developed interface become more friendly. Results show the backlash of the linear axis can be compensated less than 1μm, the backlash of the rotary axis can be compensated less than 0.001° and the shift of the axial can be compensated less than 10μm .
