回转轴

The method is :there are two perpendicular axes whose distance are controlled ,one is the axis of work table, the other is fixed with a microscope for aiming.

该测量方法是：两个相互垂直且间距可调的数控回转轴，一轴与工件的回转中心重合，另一轴上固定可移动的瞄准显微镜，当显微镜瞄准被测孔时，两轴的转角由各自的圆光栅测出，两轴之间的角度位置确定曲面壳体零件上小孔的孔位置，同时采用CCD摄像头，利用图象处理技术实现小孔的尺寸测量。
