“…This design is used for experiments conducted. The maximum material removal from the workpiece occurs at jet impact angle of 90 ∘ [18] and the garnet is the best suitable abrasive for AWJ machining polymer composite [13]. In the present investigation, irregular and angular shaped garnet abrasive particles were uniformly dispersed with water in the mixing chamber and jet was expelled through the nozzle at 90 ∘ for machining.…”

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.

“…The erosion rate was found to increase considerably for particle size up to 200 m and remain constant for further increase in the particle size. Machining performance of various abrasives on glass workpiece was investigated by Khan and Haque [13]. Taper of the machined surface was found to increase with decrease in hardness of abrasive.…”

“…This process is a well-known advanced technique for cutting difficult-to machine materials. It is a technique, which machines without heat generation and the machined surface is generated without any HAZ or residual stress virtually (Khan & Haque, 2007) This process is inert towards properties of material with high versatile and flexible in machining. The main disadvantage of this technique is its vociferous and disordered working environment (Azmir & Ahsan, 2009) AWJ machining process is nonconformist yet totally a flexible process.…”

Abrasive Water Jet Machining is one of the novel nontraditional cutting processes found diverse applications in machining different kinds of difficult-to-machine materials. Process parameters play an important role in finding the economics of machining process at good quality. This research focused on the predictive models for explaining the functional relationship between input and output parameters of AWJ machining process. No single set of parametric combination of machining variables can suggest the better responses concurrently, due to its conflicting nature. Hence, an approach of Multi-objective has been attempted for the best combination of process parameters by modelling AWJM process using of ANN. It served a set of optimal process parameters to AWJ machining process, which shows a development with an enhanced productivity. Wide set of trail experiments have been considered with a broader range of machining parameters for modelling and, then, for validating. The model is capable of predicting optimized responses.

“…Nowadays, it is necessary to fi nd a compromise solution, to take into account various factors such as economic opportunities, the technology and ecology of production. It is important to examine the eff ect of machining on functional surfaces and mechanical properties of metallic materials (Wilkins and Graham, 1993;Hloch and Valíček, 2009;Fabianová, 2007;Hascalik et al, 2007;Khan and Hague, 2007;Jegaraj and Babu, 2005;Wang and Wong, 1999;Palleda, 2007;Azmir and Ahsan, 2009).…”

In this article, we deal with a progressive production technology using the water jet cutting technology with the addition of abrasives for material removal. This technology is widely used in cutting various shapes, but also for the technology of machining such as turning, milling, drilling and cutting of threads. The aim of this article was to analyse the surface of selected types of metallic materials a er abrasive machining, i.e. by assessing the impact of selected machining parameters on the surface roughness of metallic materials.
