“…It finds application to manufacture metallic and non-metallic materials. In addition, it can be considered for abrasive high-pressure water jet machining process, since it can cut high strength and hard materials by directing a high-pressured water [1,2]. The water jet process offers reduction of cost due to elimination of toxic fumes, recast layers, slag and thermal stresses that do exist in other manufacturing processes.…”

One of the most challenging tasks in machining hard materials is to achieve super high precision with excellent surface finish. The reasons can be addressed due to its properties including high work hardening and poor machinability. Abrasive water jet (AWJ) machining is a multi-operational activity which is proven technology for generating high precision components. The carried-out work mainly intended to showcase the technical parameters which are prime importance in commercial and domestic applications. There parameters include water pressure, traverse speed, abrasive feed rate. These parameters were analyzed with respect to kerf taper and surface roughness on X5CrNi18-10 steel. In the present work key parameters such as traverse speed and outlet pressure were varied from 100 -200 mm /min and 100 -200 MPa, respectively. Apart from these two parameters abrasive feed rate was also varied in the range 360 -540 g/min. Our data from experimental procedures indicate that kerf taper and surface roughness were greatly deflect by variations in the three major parameters; traverse speed, water pressure, and abrasive feed rate. To ensure better comparison of work optimization of process parameter was also carried out. In this optimization response surface methodology and central composite design method was enabled. In addition, all the needed mathematical models were enabled and set of desired contour graphs for tested surface quality are systematically represented. Finally, the kerf taper angle behaviors were also carried out using ANOVA analysis powered by MINITAB 19.

“…However, challenges associated with the AWJM process in composite machining include issues such as surface roughness ( R a ), kerf taper ( K t ), material removal rate (MRR), delamination, and other factors that impact the quality of the manufactured products 7,8 . Conventional machining processes present various difficulties, including lower precision, cracks, delamination, and increased surface roughness 9,10 . Yuvaraj's research highlighted the significance of water jet pressure as the primary parameter influencing cutting performance, followed by abrasive mass flow rate, traverse speed, and standoff distance 11 .…”

The aim of this investigation was to delve into the impact of abrasive water jet machining (AWJM) process variables on the surface roughness (Ra) and kerf angle (Ka) of hybrid fiber‐reinforced polyester composites. Utilizing both response surface methodology (RSM) and artificial neural network (ANN) prediction models, the study sought to optimize the input parameters for abrasive water jet machining, specifically in the context of paddy straw and PALF‐reinforced polyester hybrid composites. The process parameters targeted for optimization included the abrasive flow rate, traverse rate, and standoff distance during AWJM. The investigation identified an optimal combination of AWJM parameters that effectively meets the practical requirements for machining hybrid fiber‐reinforced polyester composites. According to the RSM, the suggested optimal values for the process parameters are an abrasive flow rate set at 300 g/min, traverse speed at 110 mm/min, and standoff distance at 1 mm. The ANN exhibited robust predictive capabilities, achieving high R2 scores of 0.932 and 0.962 for surface roughness and kerf angle, respectively. To enhance the performance of abrasive water jet machining and minimize surface roughness and kerf angle, the researchers conducted an optimization of the process parameters. Subsequently, confirmation experiments were executed to validate the predictive model and fine‐tune the set of process parameters for practical application.Highlights Investigated AWJM impact on Ra value and kerf angle of hybrid composites.

“…Therefore, non-conventional cutting methods have gained much attention in recent years. Abrasive water jet (AWJ) has been investigated for cutting CFRP, with most researchers nding strong links between the bre orientation [3] and jet pressure [4] with the achievable cut quality. Wire electro-discharge machining (W-EDM) is another candidate for cutting CFRP [5], however is unsuitable for GFRP due to the materials electrical insulating properties.…”

Laser cutting is well established for cutting metals, alloys, and ceramics. However, its application for cutting fibre reinforced polymer composites is constrained due to specific challenges. The distinct optical and thermal properties of the fibres and matrix often lead to excessive thermal damage. Thick-section laser cutting of composites is an especially challenging task. The water jet guided laser (WJGL), employing a hair-thin water jet to guide the laser, has proven successful for such challenging materials. Thermal damage is minimized by effective in-situ cooling of the interaction zone by the water flow. This work evaluates the feasibility of WJGL cutting glass fiber reinforced polymer (GFRP). A WJGL system, fitted with a 400 W green nanosecond laser, was used to cut 7.5 mm thick GFRP using a multi-pass strategy. Effective cutting speeds of up to 10.1 mm/min were obtained with an average wall taper of 1.91°. Improvements in taper angle were realised via reduced effective cutting speeds (0.81°, 7.5 mm/min). Defects including charring, edge chipping, and matrix discolouration were observed. These results show that while the WJGL can cut thick GFRP with minimal defects, further work is required to enhance the productivity before the technique could be viable for widespread adoption.
