Owing to their excellent properties such as lightweight and high strength, fiber-reinforced composite materials are widely used as ideal materials for key structural components in extreme service environments (e.g., aviation, aerospace, and nuclear power). However, due to their non-uniformity and anisotropy, they have become typical difficult-to-machine materials, which are prone to cause damage during machining, thereby reducing the service life of the entire component. This review primarily summarizes the damage (including delamination, thermal damage, tool wear, and other processing damages) and suppression strategies of scholars in the process of traditional and non-traditional machining of fiber-reinforced composite materials in the past few years. Besides reviewing the research progress, the limitations of the current research were presented. From this review, it can be seen that traditional and non-traditional (e.g., laser machining) machining methods are difficult to avoid damage. Abrasive waterjet (AWJ) machining is a green and environmentally friendly machining technology. Some key issues are expected to be furtherly solved during the AWJ drilling of fiber-reinforced composite materials with low damage.

The bonding of Carbon Fibre Reinforced ThermoPlastic composites (CFRTP) and steel is of great interest nowadays. Nevertheless, the difference in machinability between dissimilar materials requires a specific machining process. Abrasive water jet machining is a flexible and environmentally friendly technology that can machine dissimilar materials at the same time with good results. However, due to the characteristics of the process and materials, geometrical defects such as taper angle can be caused by the loss of kinetic energy. In this research, the study of the final geometry in abrasive waterjet machining of a hybrid CFRTP/Steel structure. A new methodology for the evaluation of taper angle with high accuracy has been developed through image processing. In addition, the surface quality in terms of Ra and Rz has been assessed. A potential-type trend between taper and hydraulic pressure has been established for both materials. Minimum taper values between 1.5° and 5° have been obtained for both materials and stacking configurations with a combination of a hydraulic pressure of 420 MPa, an abrasive mass flow of 225 g/min and a traverse speed of 50 mm/min.

Graphene oxide (GO)-doped CFRP composites possess excellent mechanical properties for high-performance products of aircraft, defense, biomedical and chemical trades. This paper highlights a novel hybridization of the combined compromise solution-principal component analysis (CoCoSo-PCA) method to optimize multiple correlated responses during CNC milling of GO-doped epoxy/CFRP.

Taguchi [Formula: see text] orthogonal array considered for machining (milling) of composite by using Titanium aluminium nitride (TiAlN) milling cutter ([Formula: see text][Formula: see text]mm). A multivariate hybrid approach based on combined multiplication rule was utilized to evaluate the ranking of the alternatives decision process and optimize responses.

... AWJM has many advantages over other cutting methods such as high flexibility, no thermal damages, high machining adaptability with and minimum cutting forces (Wang 2010). The greatest advantages of AWJM over other cutting methods are higher material removal rate with minimal thermal defects and no hazardous slag (Ramulu et al. 2015;Mayuet et al. 2015;Kartal and Gokkaya 2013) In AWJM, due to fine abrasive particles and lesser cutting forces and deformations, good surface quality is achieved even at low thickness of material and low cutting speed. Due to demand of good surface quality for thinner components, this becomes an important factor in selecting the process and to control the manufacturing cost (Dumbhare et al. 2018;Çaydaş and Hascalık 2008;Selvakumar, Prakash, and Lenin 2018). ...

Abrasive water jet machining (AWJM) is an unconventional cutting method used in different industrial applications. The motive of this paper is to investigate the effect of traverse speed on surface roughness for a particular workpiece thickness. Three different plates of AISI 1030 steel as work-piece with thicknesses 4 mm, 6 mm and 8 mm are used to evaluate surface quality of cutting. Three response models for respective thicknesses are generated and checked on the basis of their prediction ability. It showed 8.71%, 8.11% and 7.83% error for surface roughness for three different thicknesses, respectively. Post validation, desired surface roughness values are placed in the response models for prediction of respective traverse speeds for three different thicknesses and represented in a graphical manner. This paper will help the AWJ machining operator to find out the precise cutting speed for achieving desired surface roughness.

Carbon fiber-reinforced polymer (CFRP) composites are used in aerospace applications because of their superior mechanical properties and light weight. Avoiding damage in the machining of CFRP composites is difficult using traditional methods. Abrasive water jet (AWJ) has recently become one of the preferred machining methods for CFRP composites. This study evaluated the AWJ machinability of CFRP composites having three different fiber orientation angles (M1: [0°/90°]s, M2: [+ 45°/− 45°]s, and M3: [0°/45°/90°/− 45°]s) according to the delamination factor (Df), and the average surface roughness (Ra) as quality characteristics of the drilled holes. The aim of the study was to investigate the effects of different levels of AWJ drilling parameters on the delamination factor and surface roughness and to determine the optimum drilling parameter levels that provide minimum delamination formation and surface roughness values. For this purpose, AWJ drilling experiments were carried out using the Taguchi L16 (44) orthogonal array. Water pressure (WP), stand-off distance (L), traverse feed rate (F), and hole diameter (D) were chosen as process parameters. Analysis of variance was used to determine the percentage effects of the AWJ drilling process parameters. The microscopic surface roughness and delamination formation properties of the machined surfaces were revealed using a scanning electron microscope and an optical microscope, respectively. The most effective parameters on Df and Ra in the AWJ drilling of M1, M2 and M3 CFRP materials were determined to be water pressure, and stand-off distance. Minimum Df and Ra values were obtained when AWJ drilling the M3 CFRP composite with a fiber orientation angle of [0°/45°/90°/− 45°]s. Minimum delamination formation and very good surface quality can be obtained when the optimum process parameters determined in this study are used in the planning process for the AWJ drilling of CFRP composites having different fiber orientation angles.

Predictive modeling and machining performance optimization during drilling of polymer nanocomposites reinforced by graphene oxide/carbon fiber This paper explores the parametric appraisal and machining performance optimization during drilling of polymer nanocomposites reinforced by graphene oxide/-carbon fiber. The consequences of drilling parameters like cutting velocity, feed, and weight % of graphene oxide on machining responses, namely surface roughness, thrust force, torque, delamination (In/Out) has been investigated. An integrated approach of a Combined Quality Loss concept, Weighted Principal Component Analysis (WPCA), and Taguchi theory is proposed for the evaluation of drilling efficiency. Response surface methodology was employed for drilling of samples using the titanium aluminum nitride tool. WPCA is used for aggregation of multi-response into a single objective function. Analysis of variance reveals that cutting velocity is the most influential factor trailed by feed and weight % of graphene oxide. The proposed approach predicts the outcomes of the developed model for an optimal set of parameters. It has been validated by a confirmatory test, which shows a satisfactory agreement with the actual data. The lower feed plays a vital role in surface finishing. At lower feed, the development of the defect and cracks are found less with an improved surface finish. The proposed module demonstrates the feasibility of controlling quality and productivity factors.

Fiber-reinforced polymer (FRP) composite has highly received performance characteristics of structural material. This work aims to investigate the mechanical properties and cutting quality on polymer composite designed with a multi-layer sequence of natural flax fiber interleaved with fine fly ash-reinforced vinyl ester composite by using abrasive water jet machining (AWJM). Composite laminates were made with multi-stacking of flax fiber with different fine fly ash particle filler loading (0-15 wt%) by an interleaving approach. Tensile and flexural strength of prepared laminates were measured for various fly ash filler loading conditions. Mechanical properties of laminates were limited by the agglomerated fine fly ash particles which are loading above 10 wt%. Further, enhancement of properties is attributed to the polymer chain termination by fly ash particles leading immobility of polymer link. SEM images of fracture surface revealed types of failure mode are fiber pullout, matrix cracking, and brittle failure of matrix and fiber. Analysis of surface cut quality done by varying the cutting parameters of AWJM by box Behnken design (BBD). The surface quality of the composite severely reduced with fly ash filler loading after a critical 10% loading. An increase in jet pressure intensity reduces the fiber edge pullout and damages.

Carbon fiber-reinforced thermoplastics (CFRTP) have great interest nowadays due to their excellent mechanical properties and lightness. However, in opposition to thermoset matrix composites, there is a lake in the research about machining processes of these materials. Their low glass transition temperature is a handicap when conventional machining is used. An alternative is abrasive water jet machining (AWJM) because it does not cause thermal damage. However, the surface quality produced by this process must be studied and related to the cutting parameters. This article studies the surface quality generated by water jet machining in a low melting point thermoplastic matrix composite material. The kind of thermoplastic used is a TPU (polyure-thane). The combination of a high-strength material (carbon fiber) with a low-strength material (thermoplastic matrix) makes machining difficult and can generate a poor surface finish. The influence of cutting parameters has been evaluated through an ANOVA analysis. A mathematical model that relates the surface quality with the cutting parameters has been established by means of a response surface methodology (RSM). The combination of a hydraulic pressure of 250 MPa with a traverse speed of 300 mm/min and an abrasive mass flow of 170 g/min produces the best surface quality. Finally, the main flaws when CFRTP is water jet machined have also been identified.

Carbon fiber-reinforced thermoplastics (CFRTPs) are materials of great interest in industry. Like thermosets composite materials, they have an excellent weight/mechanical properties ratio and a high degree of automation in their manufacture and recyclability. However, these materials present difficulties in their machining due to their nature. Their anisotropy, together with their low glass transition temperature, can produce important defects in their machining. A process able to machine these materials correctly by producing very small thermal defects is abrasive waterjet machining. However, the dispersion of the waterjet produces a reduction in kinetic energy, which decreases its cutting capacity. This results in an inherent defect called a kerf taper. Also, machining these materials with reduced thicknesses can increase this defect due to the formation of a damage zone at the beginning of cut due to the abrasive particles. This paper studies the influence of cutting parameters on the kerf taper generated during waterjet machining of a thin-walled thermoplastic composite material (carbon/polyurethane, C/TPU). This influence was studied by means of an ANOVA statistical analysis, and a mathematical model was obtained by means of a response surface methodology (RSM). Kerf taper defect was evaluated using a new image processing methodology, where the initial and final damage zone was separated from the kerf taper defect. Finally, a combination of a hydraulic pressure of 3400 bar with a feed rate of 100 mm/min and an abrasive mass flow of 170 g/min produces the minimum kerf taper angle.
