“…For this reason, the parameters R q (see Equation (2), the root mean square RMS to R a ) was observed as the amplitude parameters for more detailed machined surface evaluation since they respond more sensitively to local inequalities of the assessed machined surface [5]. They provide more precise information about the studied surface texture of Carrara marble used in this investigation.…”

This paper deals with an assessment of the machined surface created by abrasive waterjet technology regarding its cutting performance versus profile, lagging and waterjet angle assessments. The results of the experiments presented in this study are with regard to Carrara marble. The machined surfaces were measured in seven different locations across a 40 mm depth of cut by a high precision contact-type profilometer and thus assessed using the standardized amplitude parameters of the profile distribution. The lagging and waterjet angle were also evaluated by creating a digital photo of the machined surface together with a reference gauge. The existence of machining marks on the machined surface has been mostly noticeable in the bottom zone around ~20 mm depth of cut down to jet exit. This investigation leads to a conclusion that, stand-off distance and traverse rate play the roles of the utmost importance in considerations of the machined surface quality in contrast to abrasive mass flow rate. In addition, while the striation zone (rough surface) cannot be eliminated entirely, by selecting proper process parameters, a smooth cutting machined surface can be accomplished.

“…The current trends in environmental protection contribute to the development of non-conventional machining (NCM) methods, which include abrasive waterjet technology [3]. Abrasive waterjet (AWJ) technology is a material removal process [4] [5]. It is a state-of-the-art non-traditional machining (NTM) process [6] [7].…”

“…The manufacture of precision parts underlines the fact that the final quality appearance of the machining operations may account for approximately 15% of the total manufacturing costs estimation, thanks to the global economy. The AWJC technology process optimization has been accelerated because of the need for improvements in surface quality level [17]. The surface quality control is a very important part of the surface preparation in all types of technologies that are used for their creation.…”

Abstract:A long time ago, nature proved that even the hardest engineering materials change their shape and form when water is applied to them. The new shape formed by this phenomenon can be both valuable and/or attractive. In modern industry, water cutting technology is divided into two groups. Water jet cutting technology, which is cutting with pure water and abrasive water jet cutting technology, which uses water embedded with fine abrasive particles. Clean water jet cutting technology is suitable for "soft engineering materials" for instance paper, wood, textiles, food and plastic. It is extensively used technology in industries to cut almost everything from frozen chickens to one-use diapers. On the other hand, when "hard engineering materials" need to be cut, the addition of fine abrasive particles such as garnet allows one to cut almost any engineering material whether it be marble (as used in Al-Masjid Al-Haram, The Holy Mosque, in Makkah, KSA) or tool steel, and in thickness up to 200 mm. In this review paper, the primary objective is to highlight the state-of-the-art of the abrasive water jet cutting technology and the promise for micro-and nano-machining in modern industry.

“…The efficient use of the abrasive water jet cutting process involves analyzing the impact of process parameters on performance indicators such as cutting quality, productivity, and costs [6]. 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].…”

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.
