ABSTRACT
The paper presents the experiments performed for hydraulic abrasive cutting jet. The results are presented graphically and the influence of each factor on the cutting parameters is analyzed. It was found that if the cutting water jet is performed, the material erosion is carried out in ring surfaces, in cutting and processing with abrasive jet, the material erosion is carried out from a point or a line and then on a larger area, resulting in higher efficiency. It was also found that such as cutting and abrasive jet machining is directly influenced by the pressure of the jet, the flow of water coming into contact with the surface and the nature of the material which is subject to cutting and processing. Comparing the results of this paper, it could be noted that for the case of cutting and processing of surface the data are consistent, while for volume processing, they differ, depending on the processing speed of the material. For abrasive jet cutting and processing, it can be better approximated the behavior of the material for an abrasive action of a certain geometry. It can be also accurately determined the pressure at which cutting and processing by cracking are starting, pressure values between plastic deformation occurs, in order to smooth and hardening the surface, both for water jet and abrasive water jet .
