“…As a result, kerf widths decreased with increased traverse feed rate. The kerf angle, in turn, also decreased [34]. The increase in stand-off distance caused a significant increase in kerf width.…”

“…Higher jet expansion causes an increase in the top kerf width together with a higher kinetic energy loss of the jet. Thus, a higher stand-off distance value reduces the machining capacity of the jet, and the bottom kerf width decreases, while the kerf angle increases [34].…”

“…In addition, regression models were developed to predict kerf width. The results showed that the jet operating pressure significantly influenced the top kerf width, stand-off distance, and traverse feed rate [34]. The research carried out by El-Hofy et al included an experimental study and a statistical analysis on the cutting of multidirectional CFRP laminates.…”

In this study, carbon fiber-reinforced polymer (CFRP) composites with three different fiber orientation angles (M1: [0°/90°] s , M2: [+ 45°/− 45°] s , and M3: [0°/45°/90°/− 45°] s) were drilled (with and without pilot holes) on an abrasive water jet (AWJ) machine and the effect of the drilling parameters on the kerf angle (K) and roundness error (Re) of selected holes was investigated to determine quality characteristics. The first aim of the study was the single-objective optimization of drilling parameters for minimum K and Re individually. The second aim was the multi-objective optimization of drilling parameters for the simultaneous minimization of both K and Re. The Taguchi method was applied for single-objective optimization, while all steps of the Taguchi-based gray relational analysis were used for multi-objective optimization. Drilling experiments were performed using the L16 (4 4) orthogonal array. Four levels each for water pressure, stand-off distance, traverse feed rate, and hole diameter were selected as control factors. Analysis of experimental findings revealed that pilot drilling improved the kerf angle of the hole by 12.4% and the roundness error by 22.87%. Minimum kerf angle and roundness error were realized in the AWJ drilling of the M3 CFRP. The most effective parameter on kerf angle and roundness error in AWJ drilling of M1, M2, and M3 CFRP materials was water pressure (80.6%, 76.9%, and 73.8%, respectively), followed by stand-off distance (11.7%, 12.0%, and 13.5%),while other drilling parameters remained below 10%. The statistical evaluation and optimization results in this study can contribute to the evaluation of the AWJ machinability of CFRP composites.

“…Garnet produced smaller cutting width, and large taper angle compared to silicon carbide and aluminum oxide, while silicon carbide produced high cutting width and smaller taper owing to its high hardness compared to the other two abrasive particles. Dorewswamy et al [71] studied the effect of abrasive concentration on kerf taper using graphite filled GFRP composite as work material and garnet abrasive in the form of #80 mesh size. Abrasive concentration varied from 6 to 14 wt%.…”

Fiber-reinforced composites have established as a high-performance composite of modern advanced structures in various sectors such as automotive, aerospace, and marine industries. Non-conventional machining processes are preferred for the ease of manufacturing operations, which incorporates the machining of high strength and anisotropic material. Non-conventional manufacturing processes produce complicated shaped profiles and better surface characteristics. Abrasive water jet (AWJ) machining is an emerging technology that offers an excellent alternative among the various advanced machining processes due to its process capabilities and excellent machining quality. AWJ machining has fascinated immense attention in the fields of fiber-reinforced composite materials to produce intricate industrial components and attracted the researchers and production industries. It has become well-known in all key areas of researches. Over the past 30 years, lots of research work has been carried out to describe the machining performances among the studied process parameters. This paper reviews the research progresses and integrated functions of AWJ machining in terms of mechanism and machining performances, which includes aspects such as mathematical modeling and optimization. AWJ machining procedure and performance capability are reviewed and depicted in detail. Also, a comprehensive conclusion of this review, along with future perspective, is explored subsequently. The current review work will help future researchers for the proper selection of different FRP material composite compositions and AWJ machining parameters to achieve better performances. The collection of this review literature will also support the production operations in the future.

“…The Abrasive Water Jet (AWJ) machining parameters such as jet operating water pressure (WP), transverse speed (TS), Standoff Distance (SOD), and concentration of abrasive are important for controlled cutting operation [1]. The quality of machining can be improved by controlling the AWJM parameters [2]. Water jet technology at present increasingly being used in a variety of applications including mining, process, medical and for machining of difficult-to-cut materials like composites, super alloys, rocks and ceramics [3].…”

The main aim of this investigation is to study the surface roughness produced on abrasive water jet machining of the twill weaved carbon fibre reinforced epoxy composite. Abrasive water jet machining experiment was conducted as per L9 orthogonal array, by varying water pressure, transverse speed and SOD. The performance of the composite was analysed by measuring the surface roughness. Using Taguchi analysis, the influences of input parameter over the output response was analysed. It was found that the surface roughness is highly influenced by the transverse speed.
