“…Figure 6 shows example photos of a bottom part of the sample of sheet metal after cutting, with the cutting edge and the visible area of deformation and local impact of the water-abrasive stream. After the cutting process of electrical steels, the magnetic properties of the product change along with the modification of the material texture in the deformation zone [ 36 , 37 , 38 ]. It is therefore necessary to minimize the width of this zone.…”

“…The deviations in the roughness profiles measured for lower cutting speeds (0.972 and 0.774 m/min) have smaller deviations in values than those obtained for higher cutting speeds (2.052 m/min, 1.854 m/min, and 1.29 m/min), for which there are more values above 20 µm, which may cause local defects in the electrical insulating coating on the surface of Figure 6 shows example photos of a bottom part of the sample of sheet metal after cutting, with the cutting edge and the visible area of deformation and local impact of the water-abrasive stream.

Electrical steels are magnetically soft materials and are widely used in the electrical industry for the construction of power transformer cores, distribution transformers, current transformers, and voltage transformers. An important parameter of electrical components, which determines the efficiency of devices, is energy loss during remagnetization. Energy losses are caused by eddy currents, hysteresis, and magnetic delay associated with the low quality of the cut edge after the cutting of steels, and material deformations and excessive stress concentration in the surrounding cutting zones. Common techniques for cutting electrical materials in industrial lines include mechanical cutting and laser cutting. Work has shown that mechanical cutting of electrical steel single layers results in the occurrence of large deformation zones, and in cutting processes with a high-pressure abrasive water jet (AWJ), significant uplifts of material and burrs at the bottom edges of sheets occur. The problem of increasing the cutting quality was solved through selecting the stream parameters for bundle cutting of electrical steels. It has been shown that in the process of cutting electrical sheet bundles, the height of burrs on the cut surface and the zone of plastic deformation are reduced. The work also presents comparison and analysis of characteristic features of the cut edge of electrical sheets obtained through high-pressure abrasive water jet and mechanical cutting processes. The influence of the type and processing parameters on the characteristic features of the material hysteresis loop was determined.

“…This design model covered three of the control parameters: pressure, traverse speed, and abrasive expenditure, which each took 3 levels. Control parameter ranges were chosen based on prior papers [ 40 , 41 ] and the works of different researcher teams: Hocheng et al, [ 42 ], Hlavacova et al [ 43 ], and Spadlo et al, [ 44 ]. The cutting process was carried out with the following range parameters: Traverse speed: 100–300 mm/min, The abrasive expenditure: 250–450 g/min, Pressure: 360–400 MPa.…”

Composites are materials with a heterogeneous structure, composed of two or more components with different properties. The properties of composites are never the sum or average of the properties of their components. There is a lot of research and many models on the different property assessments of composite materials. Composites are used as construction materials in key areas of technology, including in civil and mechanical engineering, aviation and space technology, and others. This work presents a modern composite material created with 3D-printing technology using the SLM method, and the possibility of its processing with one of the advanced manufacturing technologies, i.e., the Abrasive Water Jet (AWJ). Tests planned using DoE methods were carried out by changing control parameters such as the pressure, abrasive flow, and traverse speed. As a dependent parameter, the surface roughness parameter Sq (squared mean height) was selected and measured in different places of the cut composite. Based on the S/N ratio, the most favorable control parameters of the cutting process were also determined to achieve the lowest roughness of the cut surface. A clear effect of the controlled cutting process on the surface roughness was observed, as well as roughness variation for the metal and polymer component. In addition, the contact surface of the polymer with the metal in the cut zone was analyzed. Analysis of the contact surfaces on the microscope showed that the gap between the polymer–metal contact surfaces does not exceed 2.5 μm.

“…In another work, the same authors, Andrzej Perec et al, applied this AWJM to machine Hardox ® steel and optimized the process parameters to obtain a better kerf width, cutting depth, and roughness of the machined surface. For this optimization process, they used a multi-criteria optimization grey relational analysis method [16].…”

Abrasive Water Jet Machining (AWJM) is a popular machining method used to machine polymer matrix composites that are sensitive to temperature. This method is non-thermal, and each input parameter has a significant effect on output parameters, such as material removal rate, kerf width, surface roughness, and the potential for delamination. To ensure high-quality machining, it is crucial to set these input parameters at their optimal level. This paper proposes a simple approach to predict the optimum process parameters of water jet machining operations on jute fiber-reinforced polymer composite (JFRPC). The process parameters considered are standoff distance (SOD), traverse speed (TS), and abrasive material flow rate (MFR). Conversely, surface roughness (Ra) and delamination (Da) are the output parameters. Process parameters are set using Taguchi’s L27 array, with consideration given to three levels of each input parameter. The best value for process parameters is found using grey relational analysis (GRA), and an ANOVA on GRA illustrates the impact of each input variable. After a confirmation test, it was found that the suggested parameters guarantee the best possible results.
