Study on the influence of the working regime on the quality of cut in the case waterjet processing of S 235 steel

Abstract

Abstract The current paper presents the influence of different working regimes on the quality of cuts performed by abrasive water jet processing on S 235 steel. Four process parameters were varied: pressure (P), feed rate (Vf), quantity of abrasive material (Q) and distance between the cutting head and workpiece (h). Four quality parameters were analysed: width of the processed surface at the jet inlet (Li), width of the processed surface at the jet outlet (Lo), inclination angle of cut (α) and surface roughness (Ra). The analysis was done for three material thicknesses: 1mm, 6.5mm and 10mm.
