或者测量两边的距离在计算差值,

谢谢三楼回复 同时请帮忙看下第二个问题，评价第三个位置度的方法正确不

建议用位置度测量。。。。。。。。

建议版主提高发贴的容量，真要认真发个贴却发现上图也太大，贴子又太长折腾了好久，呵呵

[attachimg]2402[/attachimg] 1.图中位置度1与同心度一样吗； 2. 用0.682上边平面做Z平面, 0.622的一边做X轴,0.4993所在平面取点做X轴原点,Y轴原点取X轴上建立坐标系 3. 评价图示位置度3: 先在.622另一边测一个平面,测内圆柱.4993设为基准A,在输入Y轴标称值时是应当输入-0.311还是-0.622? 请问大家我的测量有问题没有,附图为评价位置度3的截图,谢谢了 [attachimg]2404[/attachimg]
