摘　　要：本文主要针对位置度的测量,系统的解释了使用专用量具在模拟装配的情况下测量一般位置度的方法,重点探索了具有最大实体要求的位置度的测量及计算方法,通过分析计算及现场验证,使用实测数据与制图软件相结合进行判定;又结合生产现场的现状及人员状况,提供了较为方便的判定具有最大实体要求的位置度的计算方法;最后将实例得出的计算方法进行推广,得出具有最大实体要求且n处均布的位置度的计算方法,为成组被测的孔系、键系、型槽系的位置度测量提供了新思路。Aiming at the measurement of positional degree, the method of measuring general positional degree was proposed by using special measuring tools under the condition of simulated assembly. The measurement and calculation method of positional degree with maximum entity requirements was explored. It provided a convenient calculation method to determine the position degree with the maximum entity requirement. The calculation method obtained by the example was extended. The calculation method of position degree with maximum entity requirement and N uniform distribution was obtained, which provides a idea for the position degree measurement of hole system, bond system and groove system to be measured in groups.
