EN The paper discusses findings presenting the effect of traverse speed on the surface quality, obtained due to the procedure of processing with the use of abrasive waterjet (AWJ). The analyses of surface deviations were carried out for the samples of three different materials, i.e. steel S235JR, aluminium alloy PA6 and PE WUHD 1000, applied to sample cuttings within the range of traverse speeds from 25% up to 200% by using a 25% gradient. The traverse speed corresponding to 100% was factory-defined for each tested material. Barton garnet was used as an abrasive material; mesh 80. The study was conducted with the maintenance of constant water jet pressure and the abrasive mass flow rate of 350 MPa and 148 g/min, respectively. According to the guidelines of EN ISO 9013:2017-04 standard, the analysis of two parameters characterizing a cutting-site groove shape was made, namely thickness diminution (Δa) and deviation from perpendicularity or inclination (u). Hence, surface deviation values were found in terms of macrogeometry. Based on the conducted studies, the effect of the AWJ processing speed values on the geometry of a produced groove was defined and depicted as a trendline. Also, we have drawn conclusions on the possibilities to find an optimum machining speed for a given material, which would enable us to obtain the most favourable final geometry. The authors are therefore convinced that it is possible to obtain favourable surface finish of semi-products after the AWJ machining.
