There are more and more complex products on the market, which also affects the measurement of their properties. Measurement with the coordinate measuring technique is extremely important for the precise determination of product quality. When comparing measurements on different measuring machines, deviations can occur, which leads to the problem of distrust in a specific machine. In the final assignment, we reviewed basic metrology concepts. We examined the factors affecting the measurement uncertainty and described various measurement strategies and circle equalization procedures. Dimensional measurements were performed on two different measuring machines with manual and automatic measurement methodes, which were performed and programmed in two different measuring software. We compared the measurement process itself and the measurement results. We found that all measured dimensions are in accordance with the technical drawing. Some dimensions vary, others are very comparable. Through repeated measurements, we have shown that repeatability is worse with manual measurements on the machine.
