Surface texture in abrasive waterjet cutting

A soft computing approach for controlling the quality of cut with abrasive waterjet cutting system experiencing orifice and focusing tube wear

“…From the mean response graph, it can be seen that the surface quality at the smooth zone has decreased with an increase in abrasive flow rate and the same is improved with an increase in traverse rate. This is in agreement with earlier studies [12][13][14]. Further, it can be noticed that the surface roughness is reduced with larger sizes of focusing tubes.…”

Experimental study and modelling of abrasive water jet cutting of aluminum alloy 2024

“…With further increase of water pressure, the quality of surface deteriorates dramatically. This was also observed by Kovacevic [25] and Ramulu et al [26] . The pressure increase leads to energy increase in jet outer rim which tends to more irregularities.…”

Predicting Surface Roughness and Delamination When Abrasive Waterjet Machining Fiber Reinforced Polymer Composites

“…Fig. 3.4 shows that the measured [49] and CFD predicted pressures are in good agreement, and the model is capable of accurately predicting the water hammer brought on by the liquid jet impact. Although the model used for validation is different than that used in the composite modeling of the present work, this result nevertheless lends confidence to the validity of the modeling approach.…”
