| Summary: | The abrasive water jet cutting technology is a new and modern technology which uses an abrasive material carried by water at high pressure to pierce and cut a desired material. It is a technology used to cut a high variety of materials, from rocks to glass, metal or even human tissue. Regarding the metal cutting using AWJ technology, the surface roughness is a very important aspect when it comes to surface quality and precision. This paper presents a series of aspects regarding the surface roughness on a C45 steel part cutted using AWJ technology, presenting the variation of the surface roughness and the aspect resulted after cutting, on the surface of the cut.
