“…Ultra-precision polishing technology such as fluid jet polishing, abrasive air jet polishing, and disc hydrodynamic polishing can be successfully used to suppress the occurrence of brittle fractures of optical glasses and obtain an ultra-smooth surface [6][7][8]. During these polishing processes, optical materials are removed by repeated impacts of abrasive particles in the polishing slurry [9,10]. Therefore, studying the single-particle erosion mechanism is necessary to improve our understanding of the material removal and damage control mechanism in the non-contact polishing process, as well as achieve the high-efficiency, damage-free, and ultra-smooth processing of optical glasses.…”

The study of the single-particle erosion mechanism is essential to understand the material removal mechanism in the non-contact polishing process and ultimately ensure the high-efficiency, non-damage, and ultra-smooth processing of optical glass. In this study, the theoretical model of smoothed particle hydrodynamics (SPH) is established to reveal the dynamic removal process of a single particle impacting the optical glass. The single-particle erosion mechanisms, which include ductile–brittle transition, crack initiation, and propagation, are discussed in detail through theoretical simulation. A series of particle impact experiments are designed to validate the correctness of the SPH model. The experimental data show good agreement with the simulation results in terms of the depth and width of the eroded craters. Thereafter, the SPH simulation is conducted by studying the effect of various impact parameters, such as impact speed, impact angle, and abrasive diameter, on the material removal process. With the gradual increase of impact velocity and particle size, the material removal mode changes from plastic removal to brittle removal. Although the large impact velocity and particle size increase the material removal rate, they lead to the occurrence of brittle removal and reduce the surface and sub-surface quality. When the impact angle is between 45° and 75°, the material removal rate is the largest, and the increase of the material removal rate does not cause damage to the subsurface layer of the material.

“…Li et al [119] used abrasive water jets for drilling and slitting in coal mines to improve the permeability and gas collection rate of loose coal seams and achieved good results. When it comes to difficult-to-machine composites [120][121][122], abrasive water jets are well adapted to the cold processing characteristics in the cutting of composites such as carbon fiber composites, glass-fiber-reinforced plastics, and aramid fiber, which have better cut surface quality. In the processing of multidimensional surface forming materials, multiaxis machine tool abrasive water jet processing equipment can be very good for achieving processing requirements, for example, the processing of aircraft wings, fuselages, and other large-scale curved structural parts, such as rocket shells, etc.…”

“…Increasing the machining time increases the material removal depth and also the surface roughness. When the processing time (machining time) increases, the surface profile of the machined surface was found to be smooth (Wang et al , 2016). It was seen that increasing the abrasive jet pressure will lead to an increase in machining time which in turn increases the MRR.…”

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.
