“…In this work, maximum of 2.22 g/min, the MRR was obtained. Also, it was noted that maximum pressure and minimum SOD increased the MRR in this work (Ramesha et al , 2019). Holes were made on Nickel 233 alloy using a modified air abrasive jet machining setup.…”

Purpose The purpose of the study is to machine the composites at lower machining time with higher accuracy without causing delamination. Design/methodology/approach Abrasive jet machining is the technology appropriate for machining composite materials to obtain good dimensional accuracy without causing de-lamination. The central composite design was followed in deciding the number of experiments to be carried out. Findings The influence of abrasive jet machining process parameters on machining time, material removal rate (MRR) and kerf characteristics were investigated. The experimental results proved the newly designed internal threaded nozzle increased MRR, thereby reducing the machining time. Originality/value Machining of glass fibre reinforced polymer (GFRP) is one of the challenging tasks given its non-linear and in-homogeneous properties. In this investigation, newly developed threaded and unthreaded nozzles in machining were used for making holes on the GFRP composites.

“…But initial and zone SR were affected by SOD as well as jet pressure and AMFR due to changes in kinetic energy and sharpness of cutting particles. Ramesha et al [76] performed a comparative study using AWJ machining in free air and underwater cutting of GFRP laminates. It was found that underwater machining provided lower SR, kerf width, and MRR compared to free air machining due to less jet diameter of underwater machining.…”

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.

“…There are several important input parameters that determine the quality of AWJM, namely the nozzle or traverse speed, water pressure, abrasive flow rate, type and size of abrasive grains and standoff distance [ 18 , 40 , 41 , 42 ]. The output parameters of the AWJM cutting process are surface roughness, material removal rate, and kerf taper angle.…”

“…In the case of synthetic fiber composites, Ramesha et al [ 41 ] reported that an increase in stand-off-distance (SoD) water pressure (Wp) led to the increase in MRR, but he had an entirely different view on traverse speed, since there is an inverse relationship between MRR and traverse speed ( Ts ). Ramesha et al [ 41 ] added that abrasive concentration as input parameter, could also help to obtain a higher MRR , the study conducted on glass fiber-reinforced LY556 epoxy. Meanwhile, Mullaikodi et al [ 50 ] reported that the maximum MRR was produced at higher water pressure ( Wp ) and higher abrasive flowrate, but when the traverse speed ( Ts ) was evaluated it was found that the maximum MRR was achieved at higher traverse speed ( Ts ) and medium water pressure ( Wp ) for Kevlar-glass-reinforced epoxy.…”

Cutting Processes of Natural Fiber-Reinforced Polymer Composites

Recently, natural fiber-reinforced polymers (NFRPs) have become important materials in many engineering applications; thus, to employ these materials some final industrial processes are needed, such as cutting, trimming, and drilling. Because of the heterogeneous nature of NFRPs, which differs from homogeneous materials such as metals and polymers, several defects have emerged when processing the NFRPs through traditional cutting methods such as high surface roughness and material damage at cutting zone. In order to overcome these challenges, unconventional cutting methods were considered. Unconventional cutting methods did not take into account the effects of cutting forces, which are the main cause of cutting defects in traditional cutting processes. The most prominent unconventional cutting processes are abrasive waterjet (AWJM) and laser beam (LBM) cutting technologies, which are actually applied for cutting various NFRPs. In this study, previously significant studies on cutting NFRPs by AWJM and LBM are discussed. The surface roughness, kerf taper, and heat-affected zone (HAZ) represent the target output parameters that are influenced and controlled by the input parameters of each process. However, this topic requires further studies on widening the range of material thickness and input parameter values.
