Vibration measurement is a fundamental aspect of ensuring the optimal and reliable operation of machinery, with implications for production quality, economic efficiency, and safety. The monitoring of machine condition provides essential data for the early detection of damage to machine parts, thereby preventing unanticipated failure modes and disruptions in production. Accordingly, this paper focuses on the measurement and assessment of fundamental vibration parameters, with a particular emphasis on frequency and vibration acceleration amplitude that allows to optimize the production quality assessment. Experimental measurements were conducted on a technological head of production system using abrasive water jet technology (AWJ) with a varied feed rate while cutting two types of structural steel. Based on the results of these measurements, recommendations were formulated regarding suitable and inappropriate combinations of operating parameters, thereby enhancing current knowledge regarding the influence of technological parameters on the amplitudes of vibration acceleration in the operation of production systems with AWJ technology.
