“…A maximum of 0.1394 g/s MRR was obtained for the pressure of 8 bar, nozzle diameter: 5 mm and SOD of 8 mm. When Al 2 O 3 abrasive particles were used as abrasive particles, the maximum MRR obtained in this work was 10.417 mm 3 /min (Srikanth et al , 2015). Abrasive jet drilling was conducted on CFRP composites to evaluate the factors affecting the metal removal rate.…”

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.

“…Earlier studies yielded a maximum MRR of 5.856 g/min (Srikanth and Sreenivasa Rao, 2014a, 2014b), 0.0657 g/min (Dhanawade et al , 2016) and 9.366 g/min (Rao et al , 2015). Also with carbon fibre composites, 0.6 g/min (Singh et al , 2015), 7.8 g/min (Srikanth et al , 2015) and 3.9 g/min was obtained (Srikanth and Sreenivasa Rao, 2014a, 2014b). From the present investigation, in the case of an unthreaded nozzle for a minimum pressure of 2 bar, the MRR obtained was 6.73 g/min.…”

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.
