The influence of vibrations on the quality of the processed surface is an important problem applying an industrial robot for machining prototypes. The intrinsic frequency of individual pieces of the robot may cause resonance due to vibration that appear in the machining process. The conducted experiment has investigated the activity of vibration along the process of milling wood, polypropylene and extruded polystyrene in the three-axe system. According to the influence of induced vibrations in the cutting process and considering surface roughness, feed rates for cutting taking into account every material have been chosen. Keywords: prototype machining, industrial robot, machining optimization, research on vibrational activity. Santrauka. Atliekant prototipu mechanini apdirbima pramoniniu robotu, svarbi problema yra vibracijos poveikis apdirbamo pavirsiaus kokybei. Del atskiru sujungto roboto daliu savojo daznio rezonansas gali atsirasti del apdirbimo proceso vibraciju. Atliktas eksperimentas, kurio metu istirtas roboto vibracinis aktyvumas frezuojant mediena, polipropilena ir ekstruzini polistirena triju asiu sistemoje. Kiekvienai medziagai parinktos pjovimo pastumos, atsizvelgiant i pjovimo proceso sukeliamu vibraciju itaka pavirsiaus siurkstumui. Reiksminiai zodziai: prototipu mechaninis apdirbimas, pramoninis robotas, apdirbimo optimizavimas, vibracinio aktyvumo tyrimai.
