“…The water-jet is regarded as an incompressible fluid. The Coupled Eulerian Lagrangian (CEL) method has been used by [12,24,23,15,17] to simulate the fluid/structure interaction and material erosion under water-jet impact. It has been also used to simulate tube forming and water-jet spot welding [6,7].…”

a b s t r a c tThe aim of this study is to develop a new numerical cutting model that includes fluid structure interaction and to take into account heat transfer between the water-jet, the workpiece and the chip. This has been achieved using a CEL (Coupled-Eulerian-Lagrangian) technique, an algorithm has been developed to ensure heat exchange between the fluid and the structure. This new model allows decoupling of the mechanical and the thermal effects of the water-jet on chip formation and fragmentation. It has been demonstrated that fragmentation of the chip is ensured by the combination of the thermal and the mechanical effects of the water-jet. Moreover, the tool rake temperature is reduced by more than 400°C, the tool/chip contact length is also decreased by about 30%.

“…Abrasive Waterjet (AWJ) Machine have been known for its versatility and widely used in the industry for multiple fabrication process and cleaning [4][5][6]. An AWJ related study was conducted by Junkar, Jurisevic, Fajdiga and Grah [7] to study the effect of erosion impact of a single particle abrasive with the target workpiece which is stainless steel (AISI 304). The research was done using LS Dyna where the crater spherity in the simulation was used to compare with the observation of experimental shapes of craters on the workpiece material.…”

Abstract. Computational Fluid Dynamics (CFD) softwares have been prevalent in Abrasive Waterjet (AWJ) Modelling for optimization and prediction. However, there are many different methods in approaching a single problem especially in predicting the erosion rate of nozzle which is critical in influencing kerf quality of AWJ cutting. In this paper, three main methods of assembly meshing for an abrasive waterjet erosion were simulated which is Quadrilateral, Cutcell and Tetrahedrons and each processing time, quality of convergence and accuracy of results are discussed. Results shows that Quadrilateral mesh prevails in the mentioned category followed by Tetrahedrons and Cutcell.

“…The effect of abrasive impact angle on machining of ceramic material was investigated by Srinivasu et al [18], using silicon carbide as abrasive. The effect of particle impact angle was also studied by Junkar et al [19], using finite element analysis. Authors found that maximum material removal occurs at jet impact angle of 90 ∘ .…”

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.
