The article is a response to the lack of information, especially in the area of non-destructive techniques suitable for wide practical application. The article deals with evaluation of the disintegrated material volume removed from the samples by a water jet. The study presents a quantified disintegrated material volume by means of an optical profilometer MicroProf FRT, a digital microscope VHX-5100 and X-ray computed micro-tomograph XT H 225 ST. Based on a comparison of measured data, it is possible to state that the methods of optical profilometer and a digital microscope give us very close volume values. While the values of the volume of removed material analysed by X-Ray μ-CT reach higher its values. After detailed analysis of the individual tomographic cross-sections in area of kerf surface it can be concluded that complex morphology of this surface can explain differences in the results. There are visible some re-entrant features like an overhangs and undercuts at the surface created by high pressure water jet.
