The term quality of a product means customers satisfaction with the same product. Precisely at this measurement, it has a very important role in the production process itself. Due to increasing quality requirements it is necessary to encourage further research into measurement techniques. With the increasing number of CNC machines, demand for the device grew faster and more precisely to measure the dimensions of the work piece. A coordinated measuring device playsa major role in quality control. Apart from the high precision and accuracy, some of the advantages of the device are flexibility, lowered human impact and increased productivity. The theme of this paper is Accuracy determination of 3D measurement device, which is used in MAGOFORM d.o.o. The paper consists ofa theoretical and experimental part. The introduction briefly represent the process of measurement and metrology and their role in the production, development of measurement and measurement equipment over the years. Then, the performances of the three-coordinate measuring devices are described, the characteristics of the different measuring probes, and the ways of programming and controlling the device. In the third part, an assessment of the reproducibility, reproducibility and accuracy of the measurement system is made.
