The first concern is the delamination and formation of burrs at machined edges, and the second is the effects of aging leading to mechanical deterioration. In this study, carbon FRP (CFRP) and aramid FRP (AFRP) composites were manufactured by vacuum infusion method and aged for 2 years under natural environmental conditions. Piercing with three different clearances (1%, 5%, and 10% of sheet thickness) and speed of 4 m/s were performed. Additionally, conventional drilling was carried out at a feed rate of 0.2 m/min. The highest delamination factor difference between piercing and drilling processes was calculated as 7.3% and 13.9% for CFRP and AFRP, respectively. The highest burr amounts for AFRP and CFRP composites were obtained as 91.5% and 39% at 10% clearance for piercing process and 123% and 32.1% for drilling process, respectively. Compared with drilling, piercing generates less burr formation except for CFRP composites in the case of 10% clearance and more precise hole production. It is understood that piercing results significantly improve when smaller clearances up to 5% of the sheet thickness are utilized.

One of the most common forms of damage in machined Carbon fiber-reinforced plastic (CFRP) composites is the burr formation and irregular machined surface. This current study investigates the effect of different loading of reduced Graphene Oxide (rGO) nanoflakes in modified CFRPs on the quality indices of drilled holes, including burr formation at the exit, surface roughness, and cutting forces. The Box-Behnken experimental design (BBD) was employed to conduct the drilling investigation on rGO-modified CFRP (CF/rGO) nanocomposite. The samples were prepared at three different (0.5,1.0,1.5%) weight fractions of rGO nanofiller material, and the effect of varying parameters, like drilling speed and feed rate was investigated. Digital image processing (DIP) was utilized to examine the factors contributing to burr formation at the exit of drilled holes, as measured by the Burr area Factor (BAF). The analysis of variance (ANOVA) revealed that the rGO wt.% and feed rate is the most prominent parameter while the drilling process. The optimal parametric condition was obtained as rGO wt.% = 1.0%, Drill speed = 1800 rpm, and feed rate = 60 mm/min, while the optimum responses resulted in Thrust force = 36.716 N, Torque = 0.181 Nm, Surface Roughness = 1.120 μm, and Burr area factor = 0.108. In addition, these results demonstrated that a moderate rGO wt.% loading, a higher drill speed, and a lower feed rate could produce the minimal Thrust force, Torque, Surface Roughness, and Burr area factor simultaneously. Further, the Scanning electron microscopy (SEM) findings were used to evaluate the outcomes of the optimum setting.

Although BFRP parts require mechanical drilling operations for manufacturing holes for assembly, many challenges make the drilling process difficult. Considering that the cutting force is one of the main parameters characterising the drilling process, this study aims to analyse the influence of feed (mm/rev) and cutting speed (m/min) on the thrust force and model the thrust force in the drilling of BFRP composites through response surface methodology (RSM) and advanced statistical modelling methods. In order to determine main and interaction effects and to calculate the regression coefficients and model parameters, mechanical drilling experiments were performed, and the thrust force was recorded. The raw force data were processed using fast Fourier transformation-based low-pass filtering, and then the calculated thrust force parameters were evaluated relative to various feeds and cutting speeds. In addition, results were compared with those of carbon fibre-reinforced polymer composites. The results of the validation experiments show that both RSM and advanced statistical models accurately predict the thrust force in BFRPs of 96.74% and 95.01%, respectively. However, the advanced statistical model can describe not only the maximum values of the force but also its characteristics at a coefficient of determination of 0.68.

Drilled holes are essential for assembling composite material components. Reducing drilling-induced damage and temperature effects is crucial for improved surface quality and integrity of the drilled composite. In the present work, drilling experiments were conducted on CEC, hexagonal-boron nitride (h-BN) dispersed CEC, and molybdenum disulfide (MoS2) dispersed CEC at three different levels of spindle speed, feed, and drill diameter using solid carbide twist drills. The filler concentrations used in this study were 4, 6, and 8 wt%. Analysis of variance (ANOVA) was used to determine the significance of input factors (feed, spindle speed, drill diameter, and filler concentration) on the drilling responses such as thrust force, temperature, arithmetic mean surface roughness (Ra), and push-out delamination factor (DFexit). The average drilling temperature, Ra, and DFexit of MoS2 dispersed CEC were reduced by 24.7, 46.5, and 11.3%, respectively, when compared to neat CEC. In h-BN dispersed CEC, the average drilling temperature, Ra, and DFexit were reduced by 25.2, 40.9, and 13.2%, respectively, compared to neat CEC. The lubricating properties and high thermal conductivity of filler added to epoxy are responsible for the lower temperature and improved hole surface finish. The improved delamination resistance in filler-loaded CEC is due to the strengthening of the matrix and fiber–matrix interface. Scanning electron microscopy (SEM) was used to examine the morphology of the drilled composite surface. The spindle speed of 5500 rpm, feed of 0.03 mm.rev−1, and filler loading of 4 wt% produced the minimum Ra and DFexit. The response surface method (RSM) was applied to determine the input parameters based on multi-response optimum criteria.

Elevation of cutting temperature may cause the matrix burning and rapid tool wear and also influences the thrust force, which is related to the delamination damage. In this work, micro-drilling induced temperature in the CFRP laminates has been investigated experimentally by taking into account the effects of cutting speed and feed. Thermocouple and infrared thermography methods have been used to measure the generated temperature during the process. Variation of thrust force was introduced as the micro-drill penetrates the CFRP laminate. The thrust force was also divided into its components, and the contribution of each component to the thrust force was explained. The effects of generated temperature on the thrust force were evaluated. It was derived from the temperature measurements that generated temperature is sensitive to both feed and spindle speed variations, but the feed is more effective on the generated temperature than the spindle speed in the selected range. It was observed that the thrust force changes significantly as the micro-drill cuts the carbon fibre intensive and epoxy intensive layers, and cutting temperature affects the highest thrust force significantly.

These new structural materials, which combine greater mechanical properties with low specific mass, are commonly assembled by riveted and bolted joints. The drilling operation, which represents the essential hole-making process used in the aerospace industry, proves particularly challenging when it comes to achieving damage-free holes with tight tolerances for CFRP/Al stacks in one-shot operations under dry conditions due to the dissimilar mechanical and thermal behavior of each constituent. Rapid and severe tool wear, heat damage, oversized drilled holes and the formation of metal burrs are among the major issues induced by the drilling of multi-material stacks. This paper provides an in-depth review of recent advancements concerning the selection of optimized strategies for high-performance drilling of multi-material stacks by focusing on the significant conclusions of experimental investigations of the effects of drilling parameters and cutting tool characteristics on the drilling performance of aerospace assemblies with CFRP/Al stacks and FML materials. The feasibility of alternative drilling processes for improving the hole quality of hybrid composite stacks is also discussed.

The experimental design was applied with the Taguchi method. The drilling experiments were performed using Minitab 19 software according to the Taguchi L-18 orthogonal array. The test results were evaluated based on the signal-to-noise (S/N) ratio. Two different drill bits (HSS and carbide), three different spindle speeds (750, 1000, 1500 rpm) and three different feed rates (0.05, 0.10, 0.15 mm/rev) were selected as the control factors. The effect levels of the control factors on Ra were found by applying analysis of variance (ANOVA). A confidence level of 95.62% was obtained with ANOVA analysis. The lowest Ra value was 1.279 mu m at the spindle speed of 1500 rpm and the feed rate of 0.05 mm/rev using a carbide drill bit. The drill bit type was obtained as the parameter with the highest effect with a rate of 61.33%.

This research was partly supported by the National Research, Development and Innovation Office (NKFIH) No. OTKA-PD20-134430 and UNKP-21-2-I-BME-237; and by the 9th Sino-Hungarian Intergovernmental Scientific and Technological Cooperation Project (grant no. 2021-07). AB - Basalt fibre-reinforced polymer (BFRP) composites probably tend to replace some carbon fibre-reinforced polymer (CFRP) applications due to their excellent specific strengths and sustainability. Despite the published early promising results concerning the material properties of BFRP, their application is not widespread, and their machinability is not supported widely by published experiences. The main aim of the present study is to experimentally investigate the drilling-induced geometrical damages of BFRP and CFRP composites. Drilling experiments were conducted at various feed and cutting speed levels using a solid carbide twist drill. The drilling-induced burr was analysed by a Mitutoyo 361–804 digital microscope, a Mitutoyo SJ400 surface tester recorded the surface roughness, and the microstructure was analysed by a Zeiss Evo MA 10 scanning electron microscope. The measured data were evaluated through digital image processing (DIP), response surface methodology (RSM), and analysis of variances (ANOVA). The experimental results show that drilling-induced burr is more severe and surface roughness is worse in BFRP than in CFRP. The composite type influenced the geometrical damages primarily, followed by the feed in the case of burrs and by the cutting speed in the case of surface roughness. The present experimental study suggests that the drilling of BFRP is even more challenging than drilling CFRP from the point of view of burr formation and micro geometrical properties.

According to the prior bibliographical studies, this material adapts well to this type of prosthesis. The objective of this research is to study its microscopic structure, in order to verify the good wetting of the fibers by the resin, the good cohesion and molding by infusion. The morphological study of the facies of the parallelepiped-shaped specimens was carried out after cuts perpendicular to the axis of the fiber strands, parallel according to the width and thickness of the specimen. This study was carried out using a scanning electron microscope (SEM), in order to determine, thanks to the typical microstructure of the composite, the various degradations, which appear as a result of the effect of static tension. The laminate used is based on three layers of carbon taffeta fabric and an orthocrylic resin. Tensile tests have been carried out at a speed of 1mm/min with a Zwick/Roell machine with a load cell of 50 kN. This speed was chosen to allow a comparative study with glass fiber specimens, which have been used previously for the production of prostheses, before those made of carbon. The microscopic study allowed to identify the four types of degradation; Matrix fracture, which manifested itself as fault lines, in preferred directions of different sizes. This contributed to interlaminar delamination. The decohesion that contributes to delamination in a different way from that of matrix breakage is visible at different levels. Interlaminar delamination results from the combined effect of matrix breakdown and decohesion and manifests itself as uneven strata. Fiber breakage was manifested by shearing. This study allowed to observing a degradation of the material imposed by static traction. As for the material used in orthopaedics, it has retained good cohesion and meets the requirements of prostheses, despite the defects detected by the microscopic study.

These materials are considered hard to cut. The delamination issues frequently arise due to their anisotropy and inhomogeneity. In aircraft manufacturing, thousands of holes are required to assemble the structural parts. Hole perpendicularity issues undoubtedly might happen during manual drilling. The main purpose of this work is to study the effects of various minor slant drilling angles on thrust force generation and delamination by using a special drill reamer. From the investigation, the drilling penetration angle significantly impacted the delamination. The delamination factor for the entry and exit sides of holes relatively decreased from 1.042 and 1.087 to 1.027 and 1.049, respectively, as the thrust force declined from 114.8 N to 106.5 N from 5° to 0° drilling angle.

Conventionally, drilling the FRPCs leads to severe inter-ply damages such as delamination and fiber pull-out, which alleviates useful attributes and causes rejection during the application of FRPCs. Research efforts have strived to optimize the process parameters while conventionally drilling holes in FRPCs. Various tool geometries and advanced motion between the tool and workpiece are also employed. Therefore, the present work reviews the drilling of FRPCs and most of its related concerns. Moreover, non-traditional drilling techniques for FRPCs are also reviewed. Nontraditional drilling methods alleviated the hole damage to a larger possible extent. Microwave drilling of FRPCs can also be explored to produce good quality holes.

AB - Carbon fiber reinforced polymers (CFRPs) have been extensively used in diverse industrial fields owing to their superior properties and excellent functions. Mechanical drilling has become a compulsory operation to shape these composites to target dimensions and desired quality for assembly purposes. Cutting-induced damages are critical issues when dealing with the manufacturing of CFRPs as they adversely affect the performance and acceptance of eventually-machined composite parts. In this paper, a critical review has been conducted to offer a comprehensive understanding of drilling-associated damages for CFRPs by focusing on illustrating the damage formation mechanisms, classification, evaluation, and suppression. Recent advances addressing the damage issues in drilling CFRPs are also carefully reviewed by critically analyzing the scientific findings reported in the open literature. The fundamental effects of the fiber layup, process parameters, tool geometries/materials, cutting environments and process strategies on the formation and progression of composite damage are discussed. The article also outlines potential solutions and strategies to suppress the formation of drilling-induced damages for CFRP composites. Both researchers and manufacturers will benefit from this review article as they seek to achieve damage-free drilling of CFRP composites.

Especially in the aerospace feld, it is a preferable material to make diferent shape thin wall sheet parts, which needs to be assembled and connected with other parts through riveting or bolt. Therefore, a large number of holes need to be drilled on the CFRP. However, as CFRP is an inhomogeneity and anisotropy laminate, defects such as delamination, burrs, tear, and excessive roughness are easy to occur in the process of drilling holes. These defects will greatly reduce the service life of structural parts or even directly make them scrap. In this review, the generation mechanism and infuencing factors of drilling defects of CFRP are explored. The relevant achievements of experimental optimization, algorithm optimization and fnite element method optimization about traditional drilling process are summarized. The research progress of new drilling processes is introduced. The shortcomings of existing research and the future development direction are analyzed. This review will help researchers optimizing the CFRP drilling process, reduce the defects in the drilling process, improve the quality of drilling holes, and provide reference for drilling process of other composite materials.

To determine an optimal setting, Taguchi coupled optimization technique has been applied with a novel approach as there is no previous work focusing on the synthesis of ultrafine silica sand taking in account the ball milling process parameters and Taguchi coupled optimization techniques. The high-grade silica was milled in planetary ball mill and the selected samples were passed through washing, crushing, dehydrating, meshing and drying operations. The samples were analyzed using Malvern Instruments for particle size distribution. The experiments were conducted as per Taguchi's L9 orthogonal array. Process parameters were analyzed using the signal-to-noise ratio based on the-smaller-the-better approach. To minimize the effect of uncontrollable variables, The ANOVA results determined the significance of the influential controllable variables so that the variability in the response is small. Optimization results confirmed that the balls to powder weight ratio were the most influential process parameter. The optimum process parameters setting concluded that balls to powder weight ratio are 20:1, the optimum ball mill working capacity is 2 L while the optimum speed of the ball mill is 105 rpm.

AB - High-strength carbon fiber-reinforced polymers have been a promising alternative to conventional fibrous composites because of their extremely high properties. Mechanical drilling is a necessary operation to create boreholes for riveting and bolting different composite structures into assemblies. However, the high-strength carbon fiber-reinforced polymers pose much more serious machining issues than the conventional ones. The present work aims to investigate the drilling performance of one type of uncoated carbide brad spur tools when applied in machining of high-strength carbon fiber-reinforced polymer laminates. The wear mechanisms of uncoated carbide brad spur drills were figured out. Additionally, the tool wear influences on the thrust force, hole dimensional accuracy, and drilling-induced delamination were quantified. The acquired results indicate that the tool wear has a significant impact on the drilling process and the quality of machined hole wall surfaces. The dominant wear mode is proved to be abrasion wear. Moreover, the uncoated brad spur drills appear to exhibit high resistance to the abrasion wear in the drilling of high-strength carbon fiber-reinforced polymer laminates.

AB - Hole making is one of the most common machining operations in fibrous composites. Holes can be produced using conventional machining technologies. However, in these cases, the size of delamination and burr appearance are often significant mostly due to the relatively large axial cutting forces. The main purpose of this research paper is to optimise and compare tilted helical milling processes in the case of carbon and glass fibre reinforced polymer (CFRP and GFRP) composites. In the scope of this research paper, numerous tilted helical milling experiments were carried out on CFRP and GFRP composites using an uncoated carbide end mill. The influences of the tilting angle and the pitch of the helical tool path on the axial cutting force were analysed and discussed based on experimental results and analytical models. In addition, machining-induced burr and microstructure were analysed using optical-digital and scanning electron microscopy, respectively. Experimental results show that both cutting force and burr are significantly influenced by pitch and tilting angle. Furthermore, the maximisation of the tilting angle is recommended in any of the cases examined in the scope of our study.

AB - Burr is one of the main macro-geometrical types of damage concerning machined features of carbon fibre reinforced polymer (CFRP) composites. Even if it does usually not weaken the strength of composite materials, it is recommended to be removed. The deburring process often leads to significantly increased operation time and cost. In both the industry and academia, digital processing of optically captured images is the most common evaluation method for burr-characterisation. Nevertheless, there is no agreement on the measures and techniques of burr-evaluation in CFRPs. Recent key papers on burr formation, measurement and evaluation in CFRPs are reviewed in an attempt to standardise and classify burr characterisation related expertise. In this paper, burr formation mechanisms, burr measurement methods and burr parameters are critically reviewed, compared and discussed. The main advantages and disadvantages of burr measures are highlighted and their possible future applications and prospects are also considered. Furthermore, burr measures reviewed are compared and discussed based on an experimental data set.

However, the relatively high thermomechanical loads generated when drilling CFRP is considerably detrimental to the cutting tool. To address this issue, in this work, a step-change in the performance of CFRP drilling was conducted by switching the cutting model from crushing/compression fracture to the shear cutting of the composite workpiece to suppress the thermomechanical loads using a novel web thinning design. To evaluate the performance of the proposed drill bit, a comprehensive comparison was carried out between the dedicated and conventional drill bit designs from thermal, mechanical, and chip formation points of view. The results show that the dedicated drill bit outperformed the conventional drill bit in terms of thrust force, temperature elevation, burr, and exit-delamination. An in-depth observation revealed that the shear cutting became dominant in the drilling with the proposed drill bit while the crushing/compression was dominant with the conventional drill bit. The transition of the phenomena was induced by the properly designed rake angle. The mechanism of material removal in CFRP drilling using the dedicated drill bit design provides a new design direction to modifying the rake angle for improving the efficiency and quality of composite material drilling.

In this paper, the electromagnetic punching experiments were carried out to investigate hole-punching quality of carbon fiber reinforced plastic laminates with various punches. The quality evaluation such as macroscopic measurement, microstructure observation and delamination analysis was implemented. As a comparison, drilling experiments and corresponding quality tests were also accomplished. The results showed that the cutting tools had significant effects on the quality of the formed holes. For electromagnetic punched holes, the edged punch was superior to flat punch and hollow punch in term of the machining accuracy, microscopic morphology and delamination defect. Comparing with drilling process, the delamination factors of edged punched holes were lower than that of drilled holes on the basic of ultrasonic C-scan technology, implying that delamination of drilled hole was severer than edged punched holes.

Drilling ability was examined operating a drilling system with different drill bits, feed rate, and spindle speed parameters. The investigation was performed by changing the tool and composite interface. Drilling experiments were carried out under the dry condition. Thrust force and drilling temperatures were measured using dynamometer and thermal camera. Peel-up and push-out delamination were evaluated using an image analyzing tool. Results show that the tribo-mechanical behavior of the drilling operation is affected at different levels by tool coating. This behavior is related to the intrinsic friction properties of coating nature. Response surface methodology was used in the evaluation of experiment results. The feed rate of 0.13 mm/rev, spindle speed of 2425 rpm and HSS-TiN drill bit are found as an optimum drilling parameters and drill type.

This diminishes the life of the produced part under fatigue loads. Thus, the producing of proper and reliable holes in woven composites requires accurate monitoring of the cutting tool wear level to safeguard the machined parts and increase process productivity and profitability. Available tool condition monitoring (TCM) systems mainly require long development lead time and extensive experimental efforts to predict the tool wear within predefined values of cutting conditions. The changes in these values require system relearning. Therefore, developing of a smart generalized TCM system that can accurately predict tool wear based on unlearned data during drilling of woven composite plates is crucial. In this work, an attempt was presented and discussed to predict the tool wear in drilling of woven composite plates at different and wide range of cutting conditions based on the drilling forces using biased learning data. A generalized heuristic model was proposed to accurately predict tool wear value. The performance of the proposed model was benchmarked with respect to four machine learning techniques namely regression tree, support vector machine (SVM), Gaussian process regression (GPR), and artificial neural network (ANN). Extensive experimental validation tests have showed that the GPR model has offered the lowest prediction error based on a reduced biased learning dataset, which represents 50% reduction in learning efforts compared with available literature. However, the developed heuristic model showed a comparable accuracy using significantly less learning efforts.

In this industry, composite materials are used extensively, mainly, Carbon Fiber Reinforced Plastics (CFRPs), which stand out by their excellent specific mechanical properties and good fatigue and corrosion resistance. The material removal process is characterized by intermittent fracture of the fibers and oscillation of the cutting forces. Furthermore, the drill bits suffer a severe tool wear produced by the abrasiveness and hardness of the carbon fibers. On the other hand, structural elements with very demanding and complex loads are made of titanium and aluminum alloys for their superior mechanical properties. This document focuses on the analysis of Ti drilling due to its high hardness and strength, poor thermal conductivity and chemical affinity with most cutting tool materials, which result in a lower machinability. In assembly processes, components made from composite materials and Ti alloys are usually joined, producing hybrid stacks, which machining imposes an extra complexity. During drilling operations, interactions may occur between these different nature materials that may affect the quality and surface integrity of the hole. In this thesis, multiple drilling operations are analyzed, from an experimental point of view, with diamond coated carbide tools for automatic drilling processes. For CFRP drilling, it was studied the influence of the cutting parameters in tool wear mechanisms and evolution, as well as in the quality and control of the machining induced damage of the hole. This combined analysis allows to optimize cutting conditions and to determine the dependence of these variables under severe tool wear. Regarding hybrid stacks, this document focuses on the analysis of the Minimum Quantity Lubrication (MQL) level influence in tool wear mechanisms and the quality of each layer in a Ti/CFRP/Ti stack. The improvement of hybrid stacks drilling processes and the optimization of the MQL lubrication level, allows to perform more holes in a single drilling operation (One Shot Drilling, OSD) and to introduce advance assembly processes.

However, this material is difficult to cut, mainly due to its inhomogeneity and anisotropic features and because of the strong wear effects of its carbon fibres. In the scope of aerospace industrial uses of this material, thousands of holes have to be machined for purposes of assembly. Nevertheless, conventional drilling technology – even if special drilling tools are used – is only moderately able to manufacture good quality holes. Wobble milling is a novel advanced hole-making technology, which has been developed to minimize machining-induced geometrical defects like delamination or uncut fibres. The main objective of the present paper is to compare wobble milling, helical milling and conventional drilling technologies concerning unidirectional CFRPs. In addition, the kinematics of wobble milling technology is discussed in detail. In the scope of this paper, numerous machining experiments were conducted in unidirectional CFRPs: herein the impact of the type of cutting tool and of process parameters on the quality of machined holes are analysed and discussed (diameter of holes, circularity error and characteristics of uncut fibres). During these investigations, experimental data were evaluated with the help of digital image processing (DIP) and with the help of analysis of variance (ANOVA) techniques. Experimental results show that the amount of uncut fibres can significantly be minimized through the application of wobble milling technology.

Artificial neural network (ANN) is developed to express thrust force and delamination factor as a function of drilling parameters. Multi-objective optimization of drilling parameters is accomplished based on Non-dominated Sorting Genetic Algorithm (NSGA-II) with thrust force, delamination factor and material removal rate as optimization objectives, delamination factor also serves as a constraint. The Pareto front of drilling response variables determined by NSGA-II consists of a large number of non-dominated solutions. In order to facilitate the experimental verification of optimization results, fuzzy C-means clustering algorithm is used to narrow down the solutions on the front to several representative ones. Conformation tests are conducted and results show that the representative solutions can give satisfactory performance with achieving a trade-off among thrust force, exit-delamination and material removal rate.

Because difficult-to-cut materials are using more and more and hole diameter is becoming bigger and bigger in the new large aircraft, hole-making is more difficult to carry out, as a result, conventional drilling process is failing to meet the requirement gradually. Helical milling is a new hole-making process for aircraft assembly, in which the cutting tool rotates on a helical path and generates the borehole. Due to the changed cutting principle, helical milling has more advantages compared with conventional drilling process, such as high quality, high efficiency, low tool cost and wide applicability. For these reasons, helical milling becomes one of the research focuses currently. Firstly, the fundamental and advantages of helical milling are expounded. Secondly, the research status of helical milling is summarized from the machining mechanism and special equipment. Finally, the development trend of helical milling for aircraft assembly is analyzed. © 2020, Press of Chinese Journal of Aeronautics. All right reserved.

The Abaqus/Explicit solver was performed to establish progressive damage model of cutting force for CFRP high-speed milling, and high-speed milling experiments with different cutting parameters were carried out. Further, the impact mechanism of fiber cutting angle and cutting parameters on cutting force, stress, and material failure during milling was explored, and the material removal mechanism in high-speed milling of CFRP was revealed. The results show that the error between the experimental and simulated of cutting forces is less than 5%, which indicates that the progressive damage model is feasible. The fiber cutting angle has significant influence on cutting force and stress in cutting process, and the cutting direction has a significant influence on cutting force. In addition, cutting parameters play a critical role in cutting force, and the feed per tooth is the most significant factor affecting the cutting force. Simultaneously, the progressive damage model predicts that the shear failure of materials mainly concentrates in the cutting area and extends along the feed direction. Finally, the material removal mechanism of CFRP in high-speed milling was revealed combining cutting force experiment.

The current work aims to experimentally investigate the influence of applying ultrasonic vibration on the machining performance during helical milling of 7075 aluminum alloy. A full factorial design of experiment is first implemented. Analysis of Variance (ANOVA) is then performed to study the effect of rotational speed (n), tangential feed (Fe), helical pitch (P) and ultrasonic vibration on the process performance. The output response variables considered in this investigation are cutting forces (axial, tangential and radial), torque and hole quality in terms of out-of-roundness, hole size error and surface roughness. The results show that the best cutting conditions to minimize the cutting forces and the diameter deviation are the rotational speed of 5000 rpm, tangential feed of 100 mm/min and helical pitch of 0.1 mm/rev with the assistance of the ultrasonic vibration. The ultrasonic vibration improves the performance of helical milling by decreasing the axial cutting forces.

Foams derived from renewable sources are a requirement of the modern world due to the increasing concern about the environment and various issues related to petroleum based foams. Much research has been conducted recently to produce foams using renewable sources; however, low mechanical strength, high flammability and low thermal stability are the matters of concern when using these foams on a commercial scale. Various approaches have been used in past to overcome these problems; including the modification of raw material or the incorporation of propertyenhancing fillers, with or without a surface treatment. In this research, different fillers (carbon fibre powder, zirconia powder, alumina powder, feldspar, kaolinite clay, copper powder and calcium carbonate nanoparticles) have been used as reinforcement to enhance the mechanical, thermal and flame retardant properties of the bio-based rigid polyurethane foams. It was observed that the addition of ceramic filler showed the improved mechanical and thermal properties. The best properties were shown by 6% zirconia with a compressive strength of 6.61 MPa and the flexural strength of 5.72 MPa. Zirconia also demonstrated an increase in T5% up to 260°C. It is also revealed that the foams with 8% carbon fibre concentration showed up to 288% increase in compressive strength. Furthermore, up to 28% decrease in the peak of heat release rate (PHRR) was observed on the incorporation of carbon fibre powder. The foams with 8% and 10% carbon fibre concentration show conductivity of 1.9 x 10-4 and 7.1 x 10-4 S/m respectively. Also, the foams incorporated with mineral filler demonstrated up to 182% increase in compressive strength and 351% increase in flexural strength. Thermal stability of these composite foams was also found to be enhanced on the incorporation of kaolinite clay filler, with an increase in 5% weight loss temperature (T5%) from 192°C to 260°C. Furthermore, the total heat release (THR), the smoke production rate (SPR) and the total smoke release (TSR) were also found to decreased remarkably on the incorporation of different fillers used in this study. Present study also investigated the impact of drilling on the residual compressive strength of bio-based rigid polyurethane foam (RPUF) composites. RPUFs have been prepared by the incorporation of copper powder in castor oil-based foams. The formulation of the samples employed for the drilling experiments was optimized by performing compressive strength, thermo-gravimetric analysis (TGA) and flammability experiments. The effect of various drilling parameters (density, feed rate, spindle speed and drill diameter) on the thrust force, delamination and, residual compressive strength has been investigated. The polynomial mathematical model reliant on the Response Surface Method (RSM) employing central composite design has been developed. It was concluded that the density is the most influential factor for maximizing the residual compressive strength, Additionally, the enhancement in residual compressive strength was observed on increasing the spindle speed, while, the feed rate shows a negligible effect on the residual compressive strength. The optimized process parameters for maximizing residual compressive strength were attained as high spindle speed and low feed rate. Furthermore, the equations designated as the coded factors are also presented to identify the relative impact of the various drilling parameters.

However, these materials are prone to delaminate during the process and the presence of these defects can be a cause of rejection of these components. Therefore, this paper aims on the study of alternative drilling strategies such as: the orbital and a new drilling strategy (called circular drilling) to reduce the delaminations extension. Holes 8 mm in diameter were obtained by using different drilling strategies and cutting conditions and their influence on the cutting forces and delamination factor was studied. (C) 2019 The Authors.

Delamination is concerning the strength of the structure and must be avoided. One of the methods which is used as a preventive measure is utilization of the support plates. In this study, wear of the micro drill was investigated by taken into account the effects of support plates. Experiments with three levels of the spindle speed and feed were performed to provide the comparison between the supported and unsupported cases. Flank wear areas of the worn micro drills were used for the evaluation. It was revealed that feed was more effective on flank wear than spindle speed for both unsupported and supported cases, materials of the support plates had an influence on the flank wear, and cutting parameters were more effective on flank wear for the supported cases.

Due to both the growing application area of composites, and the advanced construction requirements, the used thickness of the CFRP plates increases, and the necessity of drilling holes on the sides of the plates (normal II direction) becomes even more important. Many researchers studied the machinability of UD-CFRP using numerous drilling experiments at the normal I direction. However, drilling experiments at normal II and axial directions were not published yet. The main objective of the present study is to analyse and discuss the influence of a non-conventional drilling direction on hole-quality parameters and on the thrust force. Drilling experiments were carried out in unidirectional CFRP at non-conventional drilling direction, based on central composite inscribed design. Influences of feed rate and cutting speed were analysed using response surface methodology (RSM) and analysis of variance (ANOVA) techniques. Characteristics of uncut fibres were analysed using digital image processing (DIP). The results have proved that the effect of the cutting speed is more significant when drilling UD-CFRP at the non-conventional drilling direction than at the conventional one. Furthermore, the specific feed force (k(f)) in the case of the non-conventional drilling direction was more than three times higher than the k(f) in the case of the conventional one.

Usually, mechanical drilling is an important final manufacturing process for composite laminates, whereas drilling of high-strength composite laminates is very challenging and difficult. As the most undesirable damage and challenging failure mode, drilling-induced delamination for fiber reinforced composite laminates is a hot research area of immerse engineering importance. A review on the path towards delamination-free drilling for composite laminates can significantly help researchers improve currently-available cost-effective drilling process and develop high performance drilling process. This review paper summarizes an up-to-date progress in drilling-induced delamination for composite laminates reported in the literature. It covers delamination formation mechanism, delamination quantification methodologies and measurement technologies, delamination suppression strategies (including tool design optimization, drilling conditions optimization and high performance drilling methods). This general review of drilling-induced delamination for composite laminates can be referenced as not only a summary of the current results from literature survey but also future work possibilities, giving the researchers the opportunity to deepen specific aspects and explore new aspects for reaching delamination-free drilling for composite laminates.

Design/methodology/approach CFRP composite material had been fabricated having fiber orientations frequently used in the aerospace industry (0 degrees/45 degrees/90 degrees/-45 degrees). Three different stand-off distances (1, 2 and 3 mm), three different water pressures (1,800, 2,800 and 3,800 bar) and three different hole diameters (4, 8 and 12 mm) were selected as processing parameters. The average surface roughness values were obtained, and delamination damage was then analyzed using Taguchi optimization. Drilling experiments were performed using the Taguchi L-27 orthogonal array via Minitab 17 software. The signal/noise ratio was taken into account in the evaluation of the test results. Using the Taguchi method, the control factors giving the mean surface roughness values were determined. Analysis of variance was performed using the experimental results, and the effect levels of the control factors on the average surface roughness were found. Findings It was found that water pressure and hole diameter had a higher effect on average surface roughness, while water pressure and stand-off distance were effective on delamination. Originality/value The novel approach is to reduce cost and spent time using Taguchi optimization as a result of AWJ drilling the material in this fiber orientation ([0 degrees/45 degrees/90 degrees/-45 degrees](s), which is often used in the aerospace industry).

Because of the poor machinability and extreme abrasiveness of CFRP, tool wear cannot be neglected. Focusing on the CFRP drilling and countersinking thrust force of stacks, this paper provided a novel insight into the modeling of the influence of tool wear on thrust force through both experiments and theoretical analysis. The experimental exploration is first presented in this study, and the flank wear was observed and it is the primary abrasion type. Then a method of infinitesimal elements with substitution has been used to develop the theoretical model of thrust force based on the mathematical abstraction of flank wear size and morphology, and the forces of the deformation region under the wear land in the element are the increscent component which contributes a lot to the variation of the total thrust force. Finally the theoretical model is verified by the multivariate experiments, and the results show that proposed model can work well. The work in this paper enables us to understand the influence of flank wear on thrust forces through the fundamental insight of CFRP cutting process.

An understanding of cutting temperatures is rather important when dealing with high-strength CFRPs, since machining defects are likely to occur because of high temperatures (especially in the semi-closed drilling process). The friction behavior at the flank tool-workpiece interface when drilling CFRPs plays a vital role in the heat generation, which still remains poorly understood. The aim of this paper is to address the friction-induced heat based on two specially-designed tribometers to simulate different sliding velocities, similar to those occurring along the flank tool-work interface in drilling. The elastic recovery effect during the drilling process was considered during the tribo-drilling experiments. The drilling temperatures were calculated by the analytical model and verified by the in-situ experimental results gained using the embedded thermocouples into the drills. The results indicate that the magnitudes of the interfacial friction coefficients between the cemented carbide tool and the CFRP specimen are within the range between 0.135–0.168 under the examined conditions. Additionally, the friction caused by the plastic deformation and elastic recovery effects plays a dominant role when the sliding velocity increases. The findings in this paper point out the impact of the friction-induced heat and cutting parameters on the overall drilling temperature. LA - English DB - MTMT ER -
