使用平面还是圆柱体? 我应当从圆柱形零件的整个表面(平面)上取点,还是应当只检查表面(使用平面上的小平面) 取决于我如何检查零件,不同的结果不断出现。 回答: 许多几何 尺寸和公差测量 (GD&T) 计算是基于特征的尺寸,因此特征尺寸对计算有着很大影响。 当没有键入特征长度时,那么软件使用所测得的点来确定计算值...
Educating our designers in GD&T will take years. In the end, it will be worth it, but todaypeople say it's not worth the schedule slip (i.e. its more trouble than its worth) forone-of-a-kind items. I can't come up with a good argument to refute the short term schedule, one...

Fortunately, the answer to these questions is often "yes." However, as tolerance specifications become tighter, more and more parts are in the borderline area between conforming and non-conforming. This paper will discuss some cases where the interpretation of the tolerance specification will ...
