Estimation of the smooth zone maximal depth at surfaces created by Abrasive Waterjet

The paper proposes a new method for the estimation of the maximal depth of the smooth zone at surfaces created by an Abrasive Waterjet (AWJ). The new estimation is based on experimental analysis and the experimental study of stainless steel surface irregularities created by an AWJ. Surface profile parameter Ra has been obtained by means of an optical commercial profilometer MicroProf (FRT). The main emphasis is on the analysis of results for defining the process of creation of a new surface generated by the stream of an AWJ.
