摘要
从零件形位公差要素所采用的公差原则入手,讨论了在尺寸链计算中,是否应该考虑形位公差的影响以及形位公差组成环性质的判别方法,并通过实例加以说明。
The paper discusses whether geometric tolerances need to be considered and how to discriminate the consisting link of geometric tolerances is increasing link or decreasing link in calculation of dimension chain based on tolerance principle, and illuminates it by an example.
