Abrasive waterjet (AWJ) cutting technology is one of the most recent developed non-traditional processes used in industry for the processing of difficult-to-cut materials which usually lead to a pronounced wear of conventional tools and generation of damaged surfaces. The efficiency and the quality of AWJ depend on many parameters, some of them precisely controllable (e.g. water jet pressure, feed rate) while others uncontrollable (e.g. focusing tube size, waterjet orifice size). The aim of current study was to analyze the influence of feed rate at low working pressures on the quality of cuts, quantified by the parameters specified in the ISO/WD/TC44 N 1770 standard.
