本文通过对相关原则中补偿值的分析,指出了在相关原则中,当要素给定线性尺寸公差和形位公差,要求遵守包容原则或最大实体原则时,其被测要素和基准要素偏离最大实体状态时的补偿关系,并针对特例给出一些计算办法。还指出,补偿值并不等于要素的实际尺寸与最大实体尺寸之差的绝对值,尤其是基准要素的偏离量并不能使形位公差扩大,只能使形位误差的允许值扩大。
Through the analysis of the compensation value in the relevant principles, this paper points out that in the relevant principle, when the element is given the linear dimensional tolerance and the geometric tolerance, if the principle of inclusiveness or the maximum substantive principle is required, the measured element and the reference element deviate from the largest entity State of the compensation relationship, and for some special cases given some calculation methods. It is also pointed out that the compensation value does not equal the absolute value of the difference between the actual size of the element and the maximum physical size. In particular, the deviation of the reference element does not allow the expansion of the shape tolerance but only the allowable value of the shape error.
