“…Blind holes were wider (500 m) because of the erosion caused by the confined return flow from the bottom of the hole. More recently, Nouraei et al [9] used a positive-displacement slurry pump and pulsation damper to pressurize the abrasive slurry delivered from an open mixing tank. The evolution of cross-sectional profiles of holes and channels machined in borosilicate glass for varying lengths of time were predicted using an existing model that was originally developed for AJM.…”

“…2) at each pressure, as shown in Table 1. The orifice discharge coefficient (ratio of the actual mass flow rate at the orifice exit to that of an ideal orifice) was measured to be 0.60 ± 0.03 which reduced the actual jet diameter to 140 m [9]. Table 2 gives the measured jet flow rates and the calculated velocities used in the channel machining and single impact experiments.…”

“…Abrasive particles in the form of a slurry have also been used to fabricate the microchannels and micro-holes through the machining process termed as abrasive slurry jet machining (ASJM). It has been claimed that the width and depth of micro-channels can be produced by ASJM with a variation of 3 % along the channel length [6]. Another method that can generate the micro-channels with high aspect ratio (depth over width⋍16) is reported as laser-assisted thermochemical wet etching.…”

Micro-channels have been fabricated in nickelbased superalloy (Inconel 718) through laser beam machining (LBM). Two machining mediums are employed: dry and wet medium. Under the dry medium, laser beam passes through air prior to strike with target surface while under wet medium, the laser beam first travels through a layer of distilled water and reaches the substrate after. For both the machining environments, effects of laser power, pulse repetition rate, and laser scan speed on machined channels' width, depth, and taperness are investigated. A comparison of parametric effects on machined channels' profiles has been carried out for the said machining conditions. The results reveal that LBM under distilled water is more productive than LBM under air environment. In one step, wet machining conditions allow to generate a set of two microchannels, and dry conditions generate one micro-channel. Further, to achieve the optimum dimensions of micro-channels, the appropriate level of each of the investigated laser parameter is proposed.

“…Narayanan et al [31] developed model to predict the jet energy distribution by considering parameters such as abrasive particle size distribution and the effect of particle fracture. Nouraei et al [32] developed surface evolution model that can predict the shape features in micromachining of brittle material such as borosilicate glass. These models were found to be powerful tools to develop advanced jet path strategies on complex geometries using CAD/CAM by considering various process parameters including jet exposure time and orientation.…”

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.
