The Study is focused on machining of complex components in one clamping. Two methods of machining are discussed herein, with conventional machines and a multifunctional machine. The study compares the design solution of both machines as well as elements with the potential to improve the efficiency of production. Machining using conventional machines is very time-demanding, not only with regard to the machining but also preparation and transport times. With multifunctional machines we reduce the time significantly. The study includes an experiment on a selected production component. The result is more efficient production using the multi-functional machine tool and correct selection of the machines for production.
