Drilling is considered as one of the more challenging problems in the aerospace structures stringent tolerance required for fasteners such as rivets and bolts to join the mating parts for the final assembly. Fiber-reinforced polymers are widely used in aeronautical applications due to their superior properties. One of the major challenges lays in the machining such polymers is the poor drilled-hole quality which reduces the strength of the composite and leads to part rejection at the assembly stage. In addition, rapid tool wear due to the abrasive nature of composites requires frequent tool change which result in high tooling and machining costs. This review intended to give in-depth details on the progress of drilling of fiber-reinforced polymers with special attention given to carbon fiber reinforced polymers. The objective is to give a comprehensive understanding of the role of drilling parameters and composite properties on the drilling induced damage in machined holes. Also, the review looks into the drilling process parameters and its optimization techniques, and the effects of dust/ aerosols on human health during the machining process. This review will provide the scientific and industrial communities with their advantages and disadvantages through better drilled-hole quality inspection.

“…This is due the fact that at higher pulse frequency composite surface got sufficient time to burn properly. Thus, it has been observed that the range of better kerf quality characteristics may be found at the lower lamp current (160-180 Amp) and compressed air pressure (8-9 Kg/cm 2 ), moderate pulse frequency (25)(26)(27)(28)(29)(30), and higher pulse width (2.3-2.6 ms) cutting speed (100-200 mm/min). In the present study, the experiments have performed to single index optimization of the pulsed Nd: YAG laser parameters to obtain precise geometries of cut for a 1.35 mm thick hybrid Kevlar-29/Basalt fiber composite laminate.…”

“…They revealed that cutting speed and lamp current was the most significant factor for the top and bottom kerf deviation, respectively. Rao et al [28] have used response surface methodology (RSM) to optimize laser parameters such as laser power, beam scanning speed and assist gas flow rate to achieve higher cutting surface quality in terms of kerf width, taper percentage, and heat affected zone. They observed a remarkable improvement in cut quality characteristics.…”

In advanced machining techniques, laser beam cutting provides better control over the cut surface geometry in the cutting of fiber reinforced composites compared with conventional machining techniques due to its non-contact and localized processing. However, the performance of laser cutting for hybrid fiber reinforced polymer composites is yet to reveal. It has paved the way of present study, which reports on the pulsed Nd:YAG laser cutting of 1.35mm thick Kevlar-29 and Basalt fiber based hybrid composite sheet. The geometrical accuracy of the cut has been eveluated by the measured values of kerf width, kerf deviation, and kerf taper for 42 different combinations of five laser-cutting parameters such as lamp current, pulse width, pulse frequency, compressed air pressure and cutting speed. Moreover, an integrated approach based on Grey relational analysis and genetic algorithm (GRGA) has been used for the single index optimizations of different kerf qualities. Furthermore, parametric effects have been also discussed.

“…Additionally, numerous authors have proposed the entry and exit delamination influence factors [18], and the thrust force [19][20][21], torque [22] and surface roughness [23,24] have been discussed. Moreover, using statistical techniques such as the Taguchi method [25,26], response surface methodology (RSM) [27,28], gray relational analysis (GRA) and corresponding hybrid methods [29][30][31] were proposed by many authors to obtain high-quality holes using drilling. Although many researchers widely used statistical optimization techniques to solve multiobjective optimization problems simultaneously, the solutions provided by the statistical techniques are often discrete combinations of a predetermined level of process parameters, and sometimes, these combinations may not be optimum.…”

Among the various classifications of fiber-reinforced polymer composites, carbon fiber-reinforced plastic (CFRP) composite materials have great potential in aerospace, automobile and marine industries. Drilling is a common machining process of CFRP composites. Surface delamination, tearing, abrasion, denting, cutting of fibers, formation of voids, fiber bending and pullout, etc. are significant problems that occur in the drilling of CFRP composites, among which surface delamination is identified as a critical issue. By optimizing the drilling parameters, the effect of delamination can be minimized, resulting in good quality holes. The drilling process involves several critical process parameters. Therefore, achieving accurate holes during the process is extremely difficult. Three significant drilling process parameters were considered in the present investigation aimed at achieving an optimum drilling response: the thrust force and entry and exit delamination factors. An integrated response surface methodology-based particle swarm algorithm was used to obtain optimal drilling parameters. The obtained optimal settings for CFRP drilling are a drilling speed of 1100 rpm, a feed rate of 5 mm/rev, 5% CNTs and a 110° point angle. The high feed rate increases the thrust force and entry and exit delamination factors in the drilling of fabricated hybrid nano-CNT/CFRP composites.
