| 摘 要： | 阐述尺寸公差与形位公差的关系，分析不同公差原则在设计中的适用范围，介绍形位公差在不同公差原则下的处理方法。通过实例分析计算，应根据装配关系，确定形位公差的增减性，非对称形位公差不能盲目地作为减环引入装配尺寸链中。

| Abstract: | In this paper, the relationship between dimension tolerance and geometric dimension are described, applicable ran- ges of different tolerance principles in design are analyzed, and processing methods for geometric tolerance under the different tolerance principles are introduced. By example analysis and calculation, increasing and decreasing of the geometric tolerance is determined according to assembly relationship, and asymmetric geometric tolerance can＇t blindly serve as a decreasing link to be leaded into assembly dimension chain. |

| Keywords: | geometric tolerance assembly dimension chain tolerance principle extremum method tolerance analysis |
