dcterms:description
In the submitted scientific monograph, the developed method of optical detection and analysis of geometric parameters of the topography of abrasive waterjet cut wall surfaces for proposing a method of automatic quality check and control is presented. On the basis of analysis and interpretation of data obtained from the surface, a topography function Rad, which is necessary to be known for the subsequent prediction and control of abrasive waterjet cutting technology, is derived. In the framework of interpretation of measured values, relations among these parameters are systematically analysed and physico-mechanical and distributional principles governing these parameter are formulated newly. The generalization of these principles is done by means of analytically, correlationally, regressionally and empirically derived equations with a graphical representation of distribution of their functions. Based on a number of new findings beneficial to the clarification of cutting mechanism, a classification of materials according to classes of cuttability of materials using an abrasive waterjet Tcut is proposed in the submitted work. Here, a design of a closed loop control system of influencing the technology of abrasive waterjet cutting of materials depending on the continuous measurement of sound pressure level Laeq is given. By the closed loop the control of traverse speed of the cutting head vp and thus also the control of final roughness of the cut wall Rad, which is in functional relation to the traverse speed vp, is ensured. To this effect, a control loop is designed and a suitable PI controller is selected. The design is verified in Matlab-Simulink simulation environment. Results meet theoretical assumptions and requirements of present technological practice in the area of final surface topography.
