EN Coordinate measuring machines are one of the most often used measurement devices in modern industry. Keeping high level of their accuracy parameters becomes then a critical issue. In the paper, some aspects regarding CMM reverification in production conditions and periodical check were discussed. A method of periodical check was elaborated in order to obtain regular information about changes in accuracy parameters. Possible risks and consequences of lack of knowledge regarding current CMM accuracy status were indicated. The results of current research conducted on 6 CMMs with single and double column construction were shown. One common measurement program for all machines working in CNC mode was developed for repeatability. During 6 months, 106 studies were performed and 7326 points were collected. The paper presents also some extreme results of the check together with the discussion. The presented method was adapted to production conditions. Its use is associated with a small 15 min break in a working time of a coordinate measuring machine.
