System of controlling the calibration of the coordinate measuring machine




сoordinate measuring machines, system error, uncertainty, calibration uncertainty


The scientific article solves important scientific and technological problems of increasing the efficiency of the use of coordinate measuring machines and ensuring measurement accuracy. In the course of the work, a mathematical model of the system was presented, which makes it possible to assess the accuracy of contact measurements of complex curved surfaces by coordinate measuring machines and to determine evaluations of measurement results based on uncertainty. It has been shown that the actual measurement error can be much larger than the certified measurement error due to uncertainties.
