V delu bomo obravnavali karakteristike značilne za rezanje z abrazivnim vodnim curkom (AVC). Rezanje z AVC je postopek konturnega rezanja. Karakteristike rezanja, ki vplivajo na kakovost reza so hrapavost površine, koničnost reza, napaka vogala in napaka vhoda-izhoda in so opredeljene v Švicarskem standardu SN 214001. Podatke pridobljene s pomočjo novo izrezanih vzorcev, na katerih bomo opravili meritve, bomo združili s podatki iz virov in podali komentarje, ali stroj dosega zahtevane vrednosti pri različnih kvalitetah reza. Ponovne preizkuse smo opravili na aluminiju in konstrukcijskem jeklu različnih debelin in tlaku curka. Ugotovili smo, da je hrapavost površine in koničnost reza funkcija izbrane kvalitete reza, medtem ko je napaka vogala in napaka vhoda-izhoda funkcija debeline obdelovanca.

• Title: Characteristics of cutting different materials with an abrasive waterjet on the OMAX 2652A

Abstract

In this work the characteristics typical for abrasive waterjet (AWJ) cutting are evaluated and discussed. AWJ is a contour cutting process according to the Swiss standard SN 214011, the characteristics of cutting are sourface roughness, taper error, corner error and lead-in lead-out error. Data acquired through the newly cut samples is merged with data acquired from the literature review. The tests are repeated on aluminium and mild steel of various thicknesses, and various jet pressures. The results show the surface roughness and taper error depend on the selected quality of the cut, while corner error and lead-in lead-out error depend on the thickness of the workpiece.
