When using the method of processing materials by a plasma beam it is necessary to know the specific requirements for quality and economy of cutting. Vibrations occur during this process, which can have a negative effect on lifespan of the machine. Therefore currently there is greater emphasis on exploring the effects causing these vibrations. The goal of this paper is to analyze and consider the effect of input technological factors on the occurrence and size of mechanical vibration under operational conditions. It analyzes the effect of change of the feed speed on the plasma machine under the use of four beams on the acceleration amplitude and vibration frequency. Graphic dependencies are created from measured values, which are used for comparison and evaluation of the technical condition of selected device.
