Abstract: The paper deals with an application of a shadow method which enables monitoring and checking a state of surface geometry. The data obtained from the measurement of the surface topography are analysed and simultaneously interpreted with the view of a quality increase. Data analysis from the surface enables us to formulate our ideas on the mechanism of the surface establishment created by a hydroabrasive division. It offers as well the analysis possibilities of wider connections dealing with next technology development of materials hydroabrasive dividing. Further, it emphasised the creation of parameters database of surface geometry irregularities. The utilisation of the database leads to an objective projection and a technology control of materials hydroabrasive dividing so that this technology produces more efficient and simultaneously more quality final production. New knowledge about dividing mechanism should support abstractedly an option of cutting parameters which are optimal for a given material and for required parameters concerning the quality, power and general dividing economy.
