Special Issue Information

Dear Colleagues,

This Special Issue will present modern applications of high-pressure (high-energy) water jets, theoretically and in terms of research. Submitted papers should mainly concern significant research results covering the use of various types of jets, such as plain jets, pulsating jets, abrasive suspension water jets, abrasive injection water jets, cryogenic jets, etc., in machining various materials, especially structural materials (both super hard and soft) and composites, including multilayer composites, ceramic composites, food composites, etc., in technological operations of cutting, turning, milling, drilling, and others. The topics of the papers should include the behavior of the selected materials and their interaction with the working tool—a high-pressure liquid jet—in selected applications. Quality assessments, monitoring of the machining process or its control and simulation, and theoretical studies of technological processes and operations with experimental results confirming the presented conclusions will be welcomed. Articles presenting new measurement procedures, especially those concerning the surface quality obtained after machining and describing the interaction of the material with the control parameters, will also be considered.

The aim of this study was to determine the connection between oscillations in operating pressure values and the appearance of various irregularities on machined surfaces. Such oscillations are a consequence of the high water pressure generated during abrasive water jet machining. Oscillations in the operating pressure values are periodic, namely due to the cyclic operation of the intensifier and the physical characteristics of water. One of the most common means of reducing this phenomenon is installing an attenuator in the hydraulic system or a phased intensifier system. The main hypothesis of this study was that the topography of a machined surface is directly influenced by the inability of the pressure accumulator to fully absorb water pressure oscillations. In this study, we monitored changes in hydraulic oil pressure values at the intensifier entrance and their connection with irregularities on the machined surface—such as waviness—when cutting aluminum AlMg3 of different thicknesses. Experimental research was conducted in order to establish this connection. Aluminum AlMg3 of different thicknesses—from 6 mm to 12 mm—was cut with different traverse speeds while hydraulic oil pressure values were monitored. The pressure signals thus obtained were analyzed by applying the fast Fourier transform (FFT) algorithm. We identified a single-sided pressure signal amplitude spectrum. The frequency axis can be transformed by multiplying inverse frequency data with traverse speed; in this way, a single-sided amplitude spectrum can be obtained, examined against the period in which striations are expected to appear (in millimeters). In the lower zone of the analyzed samples, striations are observed at intervals determined by the dominant hydraulic oil pressure harmonics, which are transferred to the operating pressure. In other words, we demonstrate how the machined surface topography is directly induced by water jet pressure frequency characteristics. Full article
