“…Zhang et al [66] found that cutting width and depth decreased with decrease in nozzle diameter. Madhu and Balasubramanian [67] used machined nozzles with and without internal thread to compare their effect on the SR of CFRP laminate using abrasive analysis at similar machining conditions. Threaded nozzle reduced the machining time and improved the MRR by 92% compared to without threaded nozzle.…”

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 increasing pressure will reduce the kerf taper, but machinability also increased. The experimental results showed that the minimum kerf taper of 0.029 obtained from 45° fiber orientation in CFRP laminate for maximum pressure (Madhu and Balasubramanian, 2017a, 2017b).…”

“…This might ensue to the jet being constrained to hold a heavier load at the identical pressure. With 50 mm abrasive particles delivered from the medium diameter nozzle (2.5 mm), the MRR is high (Madhu and Balasubramanian, 2017a, 2017b).…”

Purpose The purpose of this study is for solving many issues in production that includes processing of complex-shaped profile, machining of high-strength materials, good surface finish with high-level precision and minimization of waste. Among the various advanced machining processes, abrasive jet machining (AJM) is one of the non-traditional machining techniques used for various applications such as polishing, deburring and hole making. Hence, an overview of the investigations done on carbon fiber-reinforced polymer (CFRP) and glass fiber-reinforced polymer (GRFP) composites becomes important. Design/methodology/approach Discussion on various approaches to AJM, the effect of process parameters on the glass fiber and carbon fiber polymeric composites are presented. Kerf characteristics, surface roughness and various nozzle design were also discussed. Findings It was observed that abrasive jet pressure, stand-off distance, traverse rate, abrasive size, nozzle diameter, angle of attack are the significant process parameters which affect the machining time, material removal rate, top kerf, bottom kerf and kerf angle. When the particle size is maximum, the increased kinetic energy of the particle improves the penetration depth on the CFRP surface. As the abrasive jet pressure is increased, the cutting process is enabled without severe jet deflection which in turn minimizes the waviness pattern, resulting in a decrease of the surface roughness. Research limitations/implications The review is limited to glass fiber and carbon fiber polymeric composites. Practical implications In many applications, the use of composite has gained wide acceptance. Hence, machining of the composite need for the study also has gained wide acceptance. Social implications The usage of composites reduces the usage of very costly materials of high density. The cost of the material also comes down. Originality/value This paper is a comprehensive review of machining composite with abrasive jet. The paper covers in detail about machining of only GFRP and CFRP composites with various nozzle designs, unlike many studies which has focused widely on general AJM of various materials.

“…The benefits of RMA are (i) instance change of one location to another location, (ii) improving in the life of used tool, and (iii) can be used for 3D feature shapes. Madhu and Balasubramanian (2017) investigated the effect of newly designed with and without internal thread nozzles pressure, SOD, abrasive size and nozzle diameter as process parameters, while surface roughness (Ra) was response calculated experimentally on Carbon Fiber-Reinforced Polymer (CFRP) composite material. The results show that good surface finish with minimum internal threaded nozzle diameter, SOD, lower particle size and maximum Pressure.…”

In the past few decades, sophisticated machining industries are rapidly improved to attain the required shape of part within specific time and also not affecting/disturbing material properties. Accuracy of machined components is very important in every industry and geometrical accuracy of hole is vital in case of subassemblies of components. In this perspective, the researchers/experts updated their machinery time to time. In machining process, the mainly affected parameters are environment and time of machining zone, so in this case to overcome these problems encountered it is necessary to consider design of experiments which is having a great use in machining zone. This paper attempts new approach to produce hole within measurements on glass material using modified air abrasive jet machining (MAAJM) setup. Experiments were conducted on nickel material to evaluate the taper in machining. This (MAAJM) experimental work compared to stationary work table process is proven more accurate.
