“…Since the effects of pressure and cutting height on the kerf have not been evaluated to be statistically meaningful within the experimental conditions, abrasive consumption and cutting speed have been determined as the most effective factors for the kerf. In other studies, where different materials were cut, it is observed that the kerf decreases, when the abrasive consumption increases [12][13][14] and the kerf increases when cutting speed and cutting height increase [3,[13][14][15][16][17].…”

In this study, Inconel 718 material, which is widely used in space aircraft and defense industry and is difficult to be processed by traditional methods, has been cut off with abrasive water-jet. The effects of cutting parameters such as pressure, cutting speed, abrasive consumption and cutting height on kerf have been studied. The input levels needed to be used to obtain the minimum kerf have been determined through Taguchi analysis and the experimental test. The setup of experiment was modelled using linear regression model and an artificial neural network and the results were compared. It was seen that the artificial neural network model gives better results when compared to regression model. The results of experimental test to which the related models were applied are satisfactory.

“…More work is required to fully understand the influence of the important process parameters on surface roughness. Indeed, some techniques have been proposed for improving the surface finish and kerf quality [22,23]. The mechanism and rate of material removal during AWJC depends on the range of process parameters and the type of abrasive particles.…”

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 difference between the obtained response and the expected response is the response error, which is a nonlinear function related to entries into the system, controlled parameters and uncontrollable factors (noises) and interactions occurring [5][6] Errors that occur from one piece to another, although they are executed under the same conditions can be mitigated and managed to a minimum, thus optimizing the entire technological process.…”

Abstract. Dimensional variability arises in AWJ system from uncontrolled factors intervention or due to the variability of input signals considered fixed or due to interactions of the input signals with unexpected effects, leading to deterioration of unpredictable outcome. Number of noise factors, negatively influence the results registered, dispersion of the result values is directly proportional to the number and their effect. Stochastic influence and his unpredictable nature determine a thorough research of the hydroabrasive process. The research refers to the study of dimensional variability for different configurations of hydroabrasive liquid pressure, abrasive type and traverse velocity. This is achieved by performing the experiments statistically processed by combining of control parameters, which allow favorable conclusions on reducing variability results and on optimizing the entire process of hydroabrasive machining.
