Sažetak
The article deals with the impact of mass flow rate of abrasive in a water jet when penetrating into a material by using the vibration analysis. The vibrations of material were recorded by sensors placed on the experimental material. Values that were studied were amplitude and FFT (Fast Fourier Transform) spectrum of signal. The stainless steel AISI309 was used as the experimental material. Data recorded during the cutting process of the AWJ cutting were analysed by the LabVIEW programming environment. The paper outlines the course of the recorded data and the FFT spectrum of this signal. Presented here is only a part of the basic research focused on the application of vibrations as a feedback for on-line control of abrasive water jet.
