“…In this work, the effect of the process parameters such as stand-off distance, traverse rate and abrasive mass flow rate on the R a and W a during AWJ cutting of a 100 mm thick Carrara marble plate were analyzed. From analysing the experimental data outcomes, it has been found that the influence of the process parameters on the R a and W a are in the same fashion as reported in previous studies for other materials [15]- [20].…”

Abrasive waterjet (AWJ) cutting technology has been used extensively for the cutting and processing of almost all engineering materials because of its precise cutting technique and the lack of damage caused. Currently, the use of abrasive waterjet cutting in the natural stone industry is increasing. However, the effectiveness of abrasive waterjet cutting of natural stones is dependent on the rock properties and machine operating parameters. Consequently, this paper presents the influence of abrasive waterjet machining parameters on the surface texture quality of Carrara marble. The results have shown that the abrasive waterjet cutting process offers better cut surface texture quality of Carrara marble under certain parameter conditions as well as being more environmentally-friendly. The stand-off distance shows the opposite effect on both surface roughness and waviness. With a view to reducing the machining costs, every user tries to select the traverse rate of the cutting head to be as high as possible, but results show that increasing the traverse rate always causes a corresponding increase in terms of inaccuracy, surface roughness, R a ≈ 93.7 µm, and waviness, W a ≈ 92.6 µm. The abrasive mass flow rate is not a significant parameter during the cutting process. In all investigations, it was found that the machined surface of the marble is smoother near the jet entrance, R a ≈ 4 µm, and waviness, W a ≈ 5 µm, and increasingly becomes rougher towards the jet exit. The result also shows that the micro-hardness value of the Carrara marble was in the range of 122 HV to 124 HV.

“…The reason for maximum R a in sample 1 as compared to sample 3 is the fact that a sound weld is achieved for sample 3 as compared to the other two samples. It is clear from Figs 6,7,8,9,10,11,12. and 13 that due to excessive heat generated in the case of samples 1 and 2, flash and incomplete weld penetration occurred in them.…”

“…Selvan et al studied the effects of four different process parameters, i.e. water pressure, nozzle traverse speed, abrasive mass flow rate and standoff distance on the depth of cut on cast iron while applying the AWJ process [10]. Hlavacek et al presented the results of experiments carried out on copper with commercial purity to determine the influence of grain size on the texture of surface machined by the AWJ process.…”

Nowadays, the abrasive water jet (AWJ) technology is much in use for cutting materials into complex shapes with high dimensional accuracy. The objective of the present paper is to study the topography as well as the roughness of the surfaces in friction stir welded (FSW) joints, machined by AWJ. It discusses machinability of the FSW joints by AWJ. Subsequently, this paper makes a critical analysis of the surface properties by optical profilometer. Top and bottom surfaces, created by FSW, have also been analyzed using an optical 3D measurement system to determine the morphology and topographic parameters. FSW possesses favourable joining properties and generates a minimum heat-affected zone (HAZ) because of its comparatively low temperature coalescence. Three friction stir welding samples were prepared at 500, 710 and 1000 rpm with a welding speed of 40 mm/min on AA 6101-T6. After analysis, it was found that the sample prepared at 500 rpm and with welding speed of 40 mm/min produces a surface fit for industrial applications in terms of surface roughness and dimensional accuracy. It has also been observed that unlike other conventional or non-conventional processes, no HAZ is generated during the cutting of FSW joints by using the AWJ technology.

“…In the case of the GCI, the pits in the roughened surface are a result of cracks forming and coalescing in the graphite flakes. When the pulsed waterjet pressure applies stress on the relatively brittle GCI surface, load-induced fracture occurs by crack formation and propagation in the graphite flakes [18]. For the softer and more ductile A380, the surface profile which formed during pulsed waterjet is a result of a combination of crack coalescing, surface erosion, and plastic deformation [19].…”

This study utilized the high-pressure pulsed waterjet process and paired it with the plasma transferred wire arc technology to develop a novel technique to remanufacture damaged engine cylinder bores. The objective of this research was to eliminate the need for expensive bond-coats such as Ni-Al by optimizing the surface roughness profile of the substrate to provide acceptable mechanical bonding between the coating and the substrate. In this study, a high chrome stainless steel wire (Metcoloy #2) was plasma spray coated on a wide range of pulsed waterjet roughened surface profiles generated on grey cast iron and cast aluminum A380 alloy, the two most common engine materials. The pulsed waterjet greatly increased the adhesion strength between the substrates and the Metcoloy #2 coating. The increase in adhesion strength is a result of the formation of favorable mechanical anchoring points. Optimal pulsed waterjet parameters were determined to avoid the production of a copious roughness profile which resulted in a coating that mirrored the roughened surface profile. Additionally, if the roughness profile produced by the pulsed waterjet was insignificant the coating was removed in its entirety during detachment-based failure.
