Popis: The paper presents the results of improving the production process using the SMED method. The process improvement was carried out in a company in the construction industry, using a machine park consisting of CNC machines. The study evaluated the current state of changeover times for selected CNC machines and proposed a reduction in changeover times for the machine park analysed. By introducing changes to the changeover process on selected CNC machines, it was possible to minimise the changeover time by more than 20% on all the machines analysed. The proposed reorganisation of the CNC operators’ workstations resulted in a time reduction of approximately 61% for machine 1, 52% for machine 2 and 12% for machine 3. The installation of barcode readers on the profiles, on the other hand, made it possible to load the machining programmes into the CNC machines more quickly and resulted in a reduction in loading time of approximately 88% on average for each of the machines analysed.
