Abstract
The paper compares the quality of machined surface of graphite and aluminium alloy by abrasive waterjet using the focusing tube with a diameter of df1 = 0.5, mm and df2 = 0.78, mm. The machining was carried out using the technology of rotating workpiece disintegration by abrasive waterjet. Abrasive tangential waterjet was used to carry out the experiment (water pressure P = 400, MPa). Workpieces were clamped in the rotating chucking appliance with rotation frequency n = 300, min−1. The change in focusing tube diameter caused the change in values of roughness parameters and also caused the change of resulting shape of workpieces. Values of roughness parameters were measured using the MicroProf FRT optic profilometer.
