关于同轴度与同心度的测量方法的分析

Analysis of Measuring Method of Coaxiality and Concentricity

同轴度和同心度均属于形位公差中的表现形式,二者的有效测量,是整个机械加工操作中的重点内容之一。根据以往工作经验,对同轴度的普通测量方法进行总结,并从公共轴线法、直线度法、求距法三方面,论述了同轴度与同心度的三坐标测量法,对相关工作可以起到一定帮助作用。

Coaxiality and concentricity are the manifestations of form and position tolerance. Effective measurement of them is one of the key contents in the whole machining operation. Based on previous work experience, the common measurement methods of coaxiality is summarized, and the three-coordinate measurement methods of coaxiality and concentricity are discussed from three aspects: common axis method, straightness method and distance finding method, hoping to play a certain role in the relevant work.
