Quality control in production engineering requires periodic or regular monitoring and measurement of key dimensions of the (semi)product. There are several types of measuring methods, which are basically divided into touch and non-touch methods. Touch principle of measurement is mainly used to measure precisely defined piece sizes (diameters, inclinations, lengths…), while non-contact measurement methods are mostly used in 3D scanning for reverse engineering. Both methods have their advantages and limitations, which relate to the accuracy of measurement, the purpose of measurement, the surface properties of the measured piece, speed and cost of measurement. The master's thesis is intended to determine the limitations and advantages of individual measurement methods and to create a screening diagram from which anyone can decide on the best measurement technology, according to simple decision criteria. Each technology was evaluated on the measurement of the two bores of the sample piece, and using a screening diagram, we determined and applied individual measurement technologies also on pieces from industry. We found that based on the obtained data of time and accuracy of sample measurements and the choice of measurement technology for measuring five examples from industry, the created decision diagram is suitable for the selection of measurement technology.
