“…The analysis and prediction of the surface roughness of processed materials with abrasive water jet were studied in [21][22][23]. By applying some empirical mathematical models, the influence of the parameters of the abrasive water jet process (average size of the abrasive particles, distance between the nozzle and the surface of the test piece and the angle of impact) on the roughness of the experimentally processed surface has been highlighted [24]. An advanced tool used in [25] for predicting surface roughness parameters in abrasive water jet cutting processing (AWJC) is neural network modeling.…”

The great advantages of abrasive water jet cutting (AWJC) led to a rapid development of technology. The necessity of studying the process for different materials with weld overlay layers appeared due to the more widespread use of the process of jet cutting. Also, weld overlay is used widely in order to increase the durability of products used in the automotive industry. The complexity of shape, surface integrity, rapid processing, easy programming, low costs, and large flexibility of AWJC technology depends on the optimization of functional parameters and correct setting of machinability of cutting materials is one of the most important. A method of optimizing the process is the correct identification of machinability of welded workpieces with different hardness in layers. This research presents the new method and the experiments that validate the theoretical modeling. Average difference between the theoretical and the experimental values of machinability is small and lead to accuracy of results and demonstrates that this method can be used in practice.

The surface preparation of shiny stainless steels is a must for applying esthetic paints, effective functional plasma spray coating, laser cladding, welding, etc., applications. The current work aims for effective surface roughening and erosion MRR of SS 304 work surface using SiC abrasive jet erosion and optimization of the process parameters. The response surface approach is used to design and conduct the studies using the Box–Behnken design method. The surface topography of the eroded surfaces is examined by a 2D profilometer, 3D profilometer, and scanning electron microscope (SEM). The abrasive grit size and working gas pressure greatly affect the surface roughness of SS 304 samples. The influence of the process parameters on the variation of these topographical features is analyzed and confirmed. The working jet pressure is seen to significantly impact erosion MRR. The lower working gas pressure shows a typical influence on Ra (surface preparation) and as pressure increases, erosion MRR rises, and the surface preparation mode shifts to the erosion metal removal/cutting zone. The quality of SS 304 surface prepared from SiC abrasive jet impact is characterized by 3D profilometry.
