Sažetak
In order to estimate the accuracy of coordinate measuring machines (CMM), the recommendations of the ISO 10360-2 standard is to use gauge blocks, but other reference (calibration) gauges can be used. Besides the accuracy estimation, in this way the metrological traceability of current measuring systems is maintained and measurement uncertainty is determined, but only for these measurement tasks. Due to the complex hardware, the accuracy of these measuring systems varies from the orientation and length of the calibrated gauges. This paper presents a ball bar that is used as a reference gauge and CMM that is used for analyzing the influence of number of points for defining the center of the balls. In order to test the significance of parameters, complete design of experiment (DOE) factors were used. Also, the measurement uncertainty of CMM was estimated using the ISO 15530-3 guidelines for comparing measurement errors that are considered, for this measuring task, and the associated measurement uncertainty.
