“…Vundavilli, P. R., et al [105] deals with identifying the depth of cut in AWJ cutting technology using the fuzzy logic (FL) system. Water pressure, abrasive mass flow rate, the diameter of focusing nozzle and jet transverse speed were proposed as dependent parameters for the depth of cut.…”

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.

“…For production industries and also for other civil and mining engineering fields this process is an assured tool due to its exceptional properties of inflexible cutting, and acceptable surface roughness, minor kerf widths, expanded tool life, trouble freeform cutting, flexible process, dust free, ergonomic working conditions, and environment. These highlights make the process an ecofriendly process compared to other conventional machining processes like sawing (circular) in raw stone cutting and figuring areas (Assarzadeh et al, 2010;Vundavilli et al, 2012;Myers et al, 2016). There are abundant parameters associated with this process. The connected parameters of AWH machining process are figured out in Fig.…”

Abrasive Water Jet Machining is one of the novel nontraditional cutting processes found diverse applications in machining different kinds of difficult-to-machine materials. Process parameters play an important role in finding the economics of machining process at good quality. This research focused on the predictive models for explaining the functional relationship between input and output parameters of AWJ machining process. No single set of parametric combination of machining variables can suggest the better responses concurrently, due to its conflicting nature. Hence, an approach of Multi-objective has been attempted for the best combination of process parameters by modelling AWJM process using of ANN. It served a set of optimal process parameters to AWJ machining process, which shows a development with an enhanced productivity. Wide set of trail experiments have been considered with a broader range of machining parameters for modelling and, then, for validating. The model is capable of predicting optimized responses.

“…Kong et al [27] developed a mathematical model to predict the jet foot prints for arbitrarily moving jets in single straight paths. Vundavilli et al [28] used fuzzy logic based expert system such as simulated annealing and genetic algorithm to optimize process parameters and develop a mathematical model to predict depth of cut. Zain et al [29] also used soft computing techniques to optimize the process parameters that produced low surface roughness.…”

In the present research work, the effect of abrasive water jet (AWJ) machining parameters such as jet operating pressure, feed rate, standoff distance (SOD), and concentration of abrasive on kerf width produced on graphite filled glass fiber reinforced epoxy composite is investigated. Experiments were conducted based on Taguchi's L 27 orthogonal arrays and the process parameters were optimized to obtain small kerf. The main as well as interaction effects of the process parameters were analyzed using the analysis of variance (ANOVA) and regression models were developed to predict kerf width. The results show that the operating pressure, the SOD, and the feed rate are found to be significantly affecting the top kerf width and their contribution to kerf width is 24.72%, 12.38%, and 52.16%, respectively. Further, morphological study is made using scanning electron microscope (SEM) on the samples that were machined at optimized process parameters. It was observed that AWJ machined surfaces were free from delamination at optimized process parameters.
