摘要: 本篇論文是探討真圓度量測時,會造成誤差產生的幾種原因,有探針擺設誤差和軸誤差等,探針擺設誤差又可分為擺設位置的偏差和未對準工件圓心,軸誤差又可分為傾角誤差和平面軸誤差。本實驗利用兩個軸承對旋轉軸兩端徑向拘束,以降低轉軸傾角產生,因此僅討論探針擺設誤差和平面軸誤差,並建立量測誤差的數學模式,分析探針圓球半徑與待測圓半徑對量測誤差造成的影響,模擬其量測值的結果。 實驗的部分架設一台真圓度量測系統,使用三探針法分離平面軸誤差,並試圖找出三探針間較佳的間隔角度擺設,以降低非理想轉換函數造成之量測影響。最後實際量測一軸承工件來分離軸誤差得到輪廓數據,待濾波後利用最小平方圓求真圓度,並重覆量測數次,驗證真圓度量測儀的重覆性。
This research set up a roundness measurement machine and discuss error analysis. They have some factors to influence measurement results which are probe mounting error and spindle error. Probe mounting error includes both probe deviation and center misalignment. Spindle error can be divide into two parts. Those are tilt of the spindle and two-dimensional spindle motion. In this experiment, the tilt of spindle is reduced by constraining the spindle at its two extremities with bearings. We consider the probe mounting error and the two-dimensional spindle motion only in our approach. We present an exact geometric model while consider the radius of the probe. Finally, the simulate results are demonstrated. In the experiment, we set up a roundness measurement system and used the three-probe method to separate the two-dimensional spindle radial error motion. We arrange probes properly to reduce imperfection of the transfer function. Finally we compute the least squares roundness of a cylindrical workpiece. We measure the roundness of this cylindrical workpiece five times to verify the repeatability of our system.
