The main goal in today's production is to make as many products as possible in the shortest possible time. When machining with an abrasive water jet, this means that it is necessary to cut with the highest possible traverse speeds. Machining with a high traverse speed results in an increase in the surface roughness parameters of the surface machined with an abrasive water jet. With the increase in the thickness of the machined material, i.e. the depth of the cut, this is more and more pronounced. The aim of this work is to determine the influence of traverse speed on the roughness of the machined surface, Ra. Also, the influence of the thickness of the samples on the roughness of the processed surface, Ra, was investigated. The material of the samples was AlMg3 of different thicknesses (6, 8, 10 and 12 mm). The samples were cut with traverse speed of 200, 400, 600, 800, 1000 and 1200 mm/min. The roughness parameter of the machined surface, Ra, was measured at different depths, h and at several places along the samples. Based on the measured values of Ra, it was concluded that with the increase in traverse speed, the roughness of the machined surface increases. It was observed that the roughness parameter Ra at the same depth of measurement, h, has approximately the same values. The mathematical model, that describes the influence of traverse speed on the roughness of the machined surface was developed. This model showed satisfactory agreement with the measured values.
