“…Despite the small amount of articles studying the drilling process by AWJ technology [9,10] and the machining of hybrid titanium/graphite composite laminates [11], it is possible to find several references which have done the characterization of Ti6Al4V and CFRP materials separately [12][13][14][15][16][17][18][19]. Escobar-Palafox et al [9] and Hussein Mohammed Ali Ibraheem et al [10] developed mathematical models for predicting the quality of the hole as a function of process parameters based on statistical analysis.…”

“…Regarding the works studying the titanium and composite materials separately, Alberdi et al [16] obtained the machinability of two different CFRPs and discussed the quality of the cuts in terms of the roughness and taper angle, which are dependent on the traverse feed rate and the material thickness. Regarding the taper angle, the results were always below 3.5°.…”

In the present study, CFRP/Ti6Al4V stacks were machined with abrasive water jet using different process parameters in order evaluate the viability of AWJ industrial application as a substitute of conventional drilling. The effect of the stack configuration, the traverse feed rate, the cutting tool (combination of orifice and focusing tube diameter and abrasive mass flow rate), and the pressure over the kerf profile, taper angle, and surface roughness has been analyzed through an ANOVA analysis and related to the physical parameters of the AWJ process. As a result, a positive taper angle is observed in Ti6Al4V while a negative is observed in CFRP in almost all cutting conditions. This leads to obtain an X-type or barrel-type kerf profile depending on the stack configuration. In addition, the surface roughness can be as low as 6.5 μm in both CFRP and Ti6Al4V materials at 95 mm/min when CFRP/Ti6Al4V configuration is used.

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.

“…Further analysis of machined surface by Azmir and Ahsan [23] shows that at a jet angle of 90 ∘ glass fibers were found to be perfectly chopped. Alberdi et al [24] studied the suitability of machinability model developed for metals to use it in composite materials. The machinability index was found to vary with thickness and composition of the composite.…”

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.
