1.點的位置度：點的位置度主要是必須注意Φt, sΦt

2、軸線的位置度：此類的位置公差一般是相對于基準給定互相垂直的兩個方向。GB中此類一般用同軸度來標注。

3.面的位置度

面的位置度：面的位置度公差帶視距離為公差值且以面的理想位置為中心對稱配置的兩平行平面之間的區域。一般來說，面的理想位置是由三基面體系的理論正確尺寸確定的。如圖所示兩平行平面的位置度要求（我國GB中一般用對稱度表示此類）

找正方法：

1.以圓柱 A 找正第 1 軸，并將軸心線置原點；

2.以圓柱 A 和鍵槽 B 連線建第 2 軸；

3.測量 45度和各孔相對基準 A、B 的位置度。

結論：不允許通過坐標系的平移或旋轉對數據進行再處理。
