对91年第1期《计算技术》刊出的《端面跳动的测量与计算》一文(下称《端》文),本人有不同看法。现对文中形位公差的标注、相关原则的应用及补偿值的计算等问题进行商榷。 1.图中标有形位公差框格(?)0.03MA,其含义为该平面的端面圆跳动公差与被测要素的尺寸公差关系采用最大实体原则。但端面跳动的公差带是定向公差带,其位置随着端面的实际位置而浮动,所以其跳动公差无法从尺寸
I have a different opinion on the article entitled “Measurement and Calculation of End Bounce” published in “Computing Technology”, No. 1, 1991. Now the text of the tolerances of the position of the label, the application of the relevant principles and the calculation of compensation values and other issues for discussion. 1. The marked tolerance box (?) 0.03MA, the meaning of the plane of the surface circularity tolerance and the measured element size tolerance using the principle of the largest entities. However, the beating tolerance zone is a directional tolerance zone whose position fluctuates with the actual position of the end face, so that its runout tolerance can not be varied from the size
