Abstract:
With the carbon fiber reinforced plastic(CFRP) materials more and more widely being used in aviation, aerospace and other industries, the study of the secondary processing technology of composite materials is paid attention by scholars from home and abroad. Because the composite materials has characteristics such as high hardness, high strength, light weight, anisotropic and etc, it is easy to produce hierarchical, tearing, burrs, drawing, the collapse of block and other defects in the machining process, so it belongs to a typical difficult-to-machine materials. Firstly the type and characteristics of carbon fiber composite materials were analyzed. Basing on the basic principles of composite material machining the carbon fiber composite machining defects were analyzed, and the design and optimization suggestions of the carbon fiber composite cutting tool were put forward according to its machining characteristics. The tool solutions of the drilling problems of carbon fiber composites in different areas currently facing were explored. Under the basis of theoretical research and analysis, a new type of PCD tool was designed and developed and through comparing test the optimal edge was got. Through experimental research the tool geometry parameters and cutting parameters which were suitable for machining were analyzed, and the tool life problems were analyzed too. All these laid a foundation to realize carbon fiber composite materials cutting of high efficiency and high quality.

Abstract:
The increased use of composite materials has led to an increase in demand for facilities to machine them. There are significant differences between the machining of metals and alloys and that of composite materials, because composites are anisotropic, inhomogeneous and are mostly prepared in laminate form before undergoing the machining process. In most cases, traditional metal cutting tools and techniques are still being used. While the process of metal cutting has been well researched over the years, relatively little research has been carried out on the cutting of composite materials. This paper presents a brief review of research on the cutting of fibre reinforced polymer (FRP) composites and medium-density fibreboard (MDF). Most of the research published is concentrated on the chip formation process and cutting force prediction with unidirectional FRP materials. A review of some recent research on the prediction of cutting forces for MDF is also presented.

Abstract:
SiC/Cu composite materials were fabricated by powder metallurgy, and microstructure of composite was analyzed by means of metallographic microscope. The high speed steel tool and cemented carbide tool are used as cutters, and machining performance of SiC/Cu Composites were studied by cutting lathe and wire-electro discharge machine. The relationship between wire-electro discharge machining cutting speed and pulse interval were studied by wire-electro discharge machine. The results show that the composite cutting surface roughness increases with increasing of the content of SiC particles when the size of SiC is 40μm, while composite cutting surface roughness decreases with increasing of the content of SiC particles when the size of SiC is 20μm, the cemented carbide tolls have longer life than high-speed steel tools. The surface roughness of composite increases with the increasing of source voltage, but it decreases with increasing of pulse interval in the wire-electro discharge machining cutting conditions.

Abstract:
PurposeMetal matrix composites (MMC) has been a section which gives an overview of composite materials and owing to those exceptional physical and mechanical properties, particulate-reinforced aluminum MMCs have gained increasing interest in particular engineering applications. Owing to the toughness and abrasive quality of reinforcement components such as silicon carbide (SiC) and titanium carbide (TiC), such materials are categorized as difficult materials for machining. The work aims to develop the model for evaluating the machinability of the materials via the response surface technique by machining three distinct types of hybrid MMCs.Design/methodology/approachThe combined effects of three machining parameters, namely “cutting speed” (s), “feed rate” (f) and “depth of cut” (d), together with three separate composite materials, were evaluated with the help of three performance characteristics, i.e. material removal rate (MRR), cutting force (CF) and surface roughness (SR). Response surface methodology and analysis of variance (ANOVA) both were initially used for analyzing the machining parameters results.FindingsThe contours were developed to observe the combined process parameters along with their correlations. The process variables were concurrently configured using grey relational analysis (GRA) and the composite desirability methodology. Both the GRA and composite desirability approach obtained similar results.Practical implicationsThe results obtained in the present paper will be helpful for decision-makers in manufacturing industries, who work on metal cutting area especially composites, to select the suitable solution by implementing the Grey Taguchi and modeling techniques.Originality/valueThe originality of this research is to identify the suitability of process parameters combination based on the obtained research results. The optimization of machining parameters in turning of hybrid metal matrix composites is carried out with two different methods such as Grey Taguchi and composite desirability approach.

Abstract:
AbstractCarbon fiber-reinforced plastic (CFRP) composites are materials that are difficult to machine due to the anisotropic and heterogeneous properties of the material and poor surface quality, which can be seen during the machining process. The machining of these materials causes delamination and surface roughness owing to excessive cutting forces. This causes the material not to be used. The reduction of damage and surface roughness is an important aspect for product quality. Therefore, the experimental study carried out on milling of CFRP composite material is of great importance. End milling tests were performed at CNC milling vertical machining center. In the experiments, parameters considered for the end milling of CFRP were cutting speed, feed rate, and flute number of end mill. The results showed that damage, surface roughness, and cutting forces were affected by cutting parameters and flute number of end mill. The best machining conditions were achieved at low feed rate and four-flute end mill.

Abstract:

Automobile and aero industries have an increasing interestin materials with improved mechanical properties. However, manyof these new materials are classified as difficult-to-cut withconventional tools. It is obvious that tools, cutting processesand cutting models has to be devel-oped parallel to materialsscience. In this thesis rotary cutting tools are tested as analternative toexpensive diamond or cubic bore nitridetools.

Metal matrix composites mostly consist of a light metalalloy (such as aluminium or titanium) reinforced with hard andabrasive ceramic parti-cles or fibres. On machining, thereinforcement results in a high rate of tool wear. This is themain problem for the machining of MMCs. Many factors affect thelife length of a tool, i.e. matrix alloy, type, size andfraction of the reinforcement, heat treatment, cuttingconditions and tool properties.

In tests, the Al-SiC MMC formed a deformation layer duringmilling, probably affected by lack of cooling. The dominatingfactor for tool life was the cutting speed. Water jet or CO2cooling of turning did not provide dramatic increase in toollife. With PCD, cutting speeds up to 2000 m/min were usedwithout machining problems and BUE formation. Tool flank wearwas abrasive and crater wear created an "orange-peel type" wearsurface. PCD inserts did not show the typical increase in flankwear rate at the end of its lifetime.

The use of self-propelled rotary tools seems to be apromising way to increase tool life. No BUE was formed on therotary tool at high cutting data. The measurements indicatethat the rotary tool creates twice as good surface as PCDtools. The longest tool life was gained with an inclinationangle of 10 degrees. Tool costs per component will beapproximately the same, but rotary cutting tool allows higherfeeds and therefore a higher production rate and thus a lowerproduction cost.

The rotary cutting operation might have a potential toincrease productiv-ity in bar peeling. The lack of BUE withrotary cutting gives hope on higher tool life. The test resultsshow that tool wear was 27% lower with rotary cutting tools.Increase of cutting speed from 22 to 44 m/min did not affectcutting forces. This indicates that the cutting speed canincrease without significant change in tool wear rate.

Issues related to rotary cutting like cutting models,cutting processes, standards, tools and models have beendiscussed. A tool wear model with kinetic energy has beendiscussed.

Abstract:
Dans l’industrie aérospatiale, l’utilisation des matériaux hybrides CFRP/Ti montre une tendance à la hausse en raison de leurs propriétés mécaniques/physiques améliorées ainsi que des fonctions structurelles plus flexibles. En dépit de leurs nombreuses applications, l’usinage CFRP/Ti en perçage en une seule passe reste le principal défi scientifique et technologique de l’assemblage multi-matériaux. Par rapport au coût de production élevé et le temps des recherches basées sur des approches exclusivement expérimentales de l’usinage multi-matériaux, cette étude a pour objectif d’amener une meilleure compréhension de la coupe CFRP/Ti à travers une approche physique hybride qui fait dialoguer les méthodes numériques et expérimentales. Un modèle EF utilisant le concept de zone cohésive a été développé pour étudier l’usinabilité anisotrope de pièces structurales CFRP/Ti à des fins d’assemblage. L’approche numérique explicite, par des études préliminaires, les mécanismes de coupe clés qui contrôlent l’usinage CFRP/Ti. Par la suite, l’approche expérimentale a été conduite sous différentes conditions d’usinage en configuration de coupe orthogonale et de perçage. Une attention spéciale a été consacrée aux effets des stratégies des séquences de coupe CFRP/Ti sur la formation des endommagements d’interface induits. Ces études expérimentales et numériques ont permit (i) d’expliciter les mécanismes physiques activés qui contrôlent la coupe à l’interface ainsi que les endommagements induits par celle-ci, (ii) de préciser les effets des différentes stratégies d’assemblage multi-matériaux sur l’usinage CFRP/Ti, (iii) de définir la classification d’usinabilité CFRP/Ti, et (iv) d’analyser enfin les effets paramétriques géométrie/matériau d’outil régissant l’opération d’usinage CFRP/Ti
In modern aerospace industry, the use of hybrid CFRP/Ti stacks has experienced an increasing trend because of their enhanced mechanical/physical properties and flexible structural functions. In spite of their widespread applications, machining hybrid CFRP/Ti stacks in one-shot time still consists of the main scientific and technological challenge in the multi-material fastening. Compared to the high cost of pure experimental investigations on the multi-material machining, this study aims to provide an improved CFRP/Ti cutting comprehension via both numerical and experimental methodologies. To this aim, an FE model by using the cohesive zone concept was established to construct the anisotropic machinability of the bi-material structure. The numerical work aims to provide preliminary inspections of the key cutting mechanisms dominating the hybrid CFRP/Ti stack machining. Afterward, some systematic experimental work including orthogonal cutting and hole drilling was carefully performed versus different input cutting conditions. A special focus was made on the study of the effects of different cutting-sequence strategies on CFRP/Ti cutting output and induced interface damage formation. The combined numerical-experimental studies provide the key findings aiming to (i) reveal the activated mechanisms controlling interface cutting and subsequent interface damage formation, (ii) clarify the influences of different cutting-sequence strategies on hybrid CFRP/Ti stack machining, (iii) outline the machinability classification of hybrid CFRP/Ti stacks, and (iv) analyze finally the parametric effects of the material/tool geometry on cutting CFRP/Ti stacks

Abstract:
This study focuses on developing explicit analytical and numerical process models for mechanical micro-machining of heterogeneous materials. These models are used to select suitable process parameters for preparing and micro-machining of these advanced materials. The material system studied in this research is Magnesium Metal Matrix Composites (Mg-MMCs) reinforced with nano-sized and micro-sized silicon carbide (SiC) particles. This research is motivated by increasing demands of miniaturized components with high mechanical performance in various industries. Mg-MMCs become one of the best candidates due to its light weight, high strength, and high creep/wear resistance. However, the improved strength and abrasive nature of the reinforcements bring great challenges for the subsequent micro-machining process. Systematic experimental investigations on the machinability of Mg-MMCs reinforced with SiC nano-particles have been conducted. The nanocomposites containing 5 Vol.%, 10 Vol.% and 15 Vol.% reinforcements, as well as pure magnesium, are studied by using the Design of Experiment (DOE) method. Cutting forces, surface morphology and surface roughness are characterized to understand the machinability of the four materials. Based on response surface methodology (RSM) design, experimental models and related contour plots have been developed to build a connection between different materials properties and cutting parameters. Those models can be used to predict the cutting force, the surface roughness, and then optimize the machining process. An analytical cutting force model has been developed to predict cutting forces of Mg-MMCs reinforced with nano-sized SiC particles in the micro-milling process. This model is different from previous ones by encompassing the behaviors of reinforcement nanoparticles in three cutting scenarios, i.e., shearing, ploughing and elastic recovery. By using the enhanced yield strength in the cutting force model, three major strengthening factors are incorporated, including load-bearing effect, enhanced dislocation density strengthening effect and Orowan strengthening effect. In this way, the particle size and volume fraction, as significant factors affecting the cutting forces, are explicitly considered. In order to validate the model, various cutting conditions using different size end mills (100 &"181;m and 1 mm dia.) have been conducted on Mg-MMCs with volume fraction from 0 (pure magnesium) to 15 Vol.%. The simulated cutting forces show a good agreement with the experimental data. The proposed model can predict the major force amplitude variations and force profile changes as functions of the nanoparticles' volume fraction. Next, a systematic evaluation of six ductile fracture models has been conducted to identify the most suitable fracture criterion for micro-scale cutting simulations. The evaluated fracture models include constant fracture strain, Johnson-Cook, Johnson-Cook coupling criterion, Wilkins, modified Cockcroft-Latham, and Bao-Wierzbicki fracture criterion. By means of a user material subroutine (VUMAT), these fracture models are implemented into a Finite Element (FE) orthogonal cutting model in ABAQUS/Explicit platform. The local parameters (stress, strain, fracture factor, velocity fields) and global variables (chip morphology, cutting forces, temperature, shear angle, and machined surface integrity) are evaluated. Results indicate that by coupling with the damage evolution, the capability of Johnson-Cook and Bao-Wierzbicki can be further extended to predict accurate chip morphology. Bao-Wierzbiki-based coupling model provides the best simulation results in this study. The micro-cutting performance of MMCs materials has also been studied by using FE modeling method. A 2-D FE micro-cutting model has been constructed. Firstly, homogenized material properties are employed to evaluate the effect of particles' volume fraction. Secondly, micro-structures of the two-phase material are modeled in FE cutting models. The effects of the existing micro-sized and nano-sized ceramic particles on micro-cutting performance are carefully evaluated in two case studies. Results show that by using the homogenized material properties based on Johnson-Cook plasticity and fracture model with damage evolution, the micro-cutting performance of nano-reinforced Mg-MMCs can be predicted. Crack generation for SiC particle reinforced MMCs is different from their homogeneous counterparts; the effect of micro-sized particles is different from the one of nano-sized particles. In summary, through this research, a better understanding of the unique cutting mechanism for particle reinforced heterogeneous materials has been obtained. The effect of reinforcements on micro-cutting performance is obtained, which will help material engineers tailor suitable material properties for special mechanical design, associated manufacturing method and application needs. Moreover, the proposed analytical and numerical models provide a guideline to optimize process parameters for preparing and micro-machining of heterogeneous MMCs materials. This will eventually facilitate the automation of MMCs' machining process and realize high-efficiency, high-quality, and low-cost manufacturing of composite materials.

Abstract:
The objectives for this dissertation are to push forward the current state of knowledge in the area of machining fiber-reinforced plastic (FRP). The most common machining operation performed on these materials is drilling owing to the need for component assembly in mechanical pieces and structures. Among the defects caused by drilling, delamination appears as to be of the most critical and may occur at both the entrance and exit plane. A number of theoretical and experimental studies have been made to create an analytical model of delamination in composite laminates. In this dissertation, the critical thrust force (force which initiates the delamination) is predicted using linear elastic fracture mechanics - assuming Mode I. Delamination is investigated by studying the evolution of feed force and torque applied by the tool on the workpiece. A four components piezoelectric dynamometer KISTLER 9272 with special PC-software is used for measuring and evaluating of torque and cutting forces, when drilling two different composite materials: carbon/epoxy laminate fabricated by hand lay-up technique and glass/polyester composite made by pultrusion. Wear mechanisms and location of the wear on the tool are also investigated (with respect to cutting material). The tool wear is measured with help of a common workshop microscope and recorded with scanning electron microscope PHILIPS XL30. Drilling experiments are performed to give complex technical information (i.e. cutting conditions, tool geometry, tool wear and so on) which enables efficient machining of composite materials. Delamination-free drilling is given special emphasis in the experiments. Methods of statistical analysis (DOE) are used to determine which factors have the most influence on delamination.

Les procédés de fabrication de pièces mécaniques par enlèvement de matière (tournage, fraisage, perçage, ...) connaissent une utilisation massive dans l’industrie aéronautique et l’automobile. Les pièces obtenues par ces procédés doivent satisfaire à des propriétés géométriques, métallurgiques et à des caractéristiques de qualité. Pour répondre à ces exigences, plusieurs essais expérimentaux basés sur le choix des conditions de coupe sont souvent nécessaires avant d’aboutir à une pièce satisfaisante. Actuellement, ces méthodes empiriques basées sur l’expérience des fabricants et des utilisateurs des outils coupants sont souvent très longues et coûteuses, donnent une large plage de choix des paramètres en fonction de leurs besoins. Toutefois, le coût très élevé d’un essai limite fondamentalement le nombre d’expériences, avoir une pièce respectant les caractéristiques souhaitées avec un coût acceptable devient une tâche difficile
Manufacturing processes of mechanical parts by removal of material (turning, milling, drilling ...) have extensive use in aeronautic and automobile industry. The components obtained using these methods must satisfy geometric properties, metallurgical and quality characteristics. To meet these requirements, several experimental tests based on the selection of cutting conditions are often necessary before manufacturing. Currently, these empirical methods based on the experience of manufacturers and users of cutting tools (charts, diagrams with experimental findings, ...) are often very lengthy and costly. However, the high cost of a trial limits the number of experiments, so to have a deserted component with an acceptable cost is a difficult task. The importance of cutting conditions monitored by limitations is related to the type of material to be machined, since it determines the behavior of the machining

Abstract:
This research explores the relative merits of existing and novel ultra-hard tool materials for finish turning titanium alloys. Phase 1 of the experimental work comprised evaluating the machinability of Ti-6Al-2Sn-4Zr-6Mo when employing carbide tooling with respect to tool life, wear behaviour, workpiece surface integrity and cutting forces. The machinability of Ti-6Al-2Sn-4Zr-6Mo using PCBN tooling was evaluated in Phase 2 experiments. It was shown that even with the use of high pressure jet cooling, carbide and low content PCBN grade inserts were unsuitable for high-speed (~200 m/min) finish turning of titanium alloys. Phase 3 research evaluated the machinability of Ti-6Al-2Sn-4Zr-6Mo and Ti-6Al-4V when employing PCD tooling with respect to tool life, wear behaviour, workpiece surface integrity and cutting forces. Benchmark tests producing response surface models were developed using conventional low pressure fluid supply and were found to be suitable for the prediction of tool life, surface roughness and cutting force within the range of parameters studied. The PCD inserts significantly outperformed both carbide (by a factor > 24) and PCBN (by a factor > 12) tools in high-speed finish turning, although the performance varied depending on the PCD structure, edge geometry, period of engagement, undeformed chip thickness and jet fluid parameters.

Abstract:
Metal matrix composites due to their excellent properties of high specific strength, fracture resistance and corrosion resistance are highly sought after over their non-ferrous alloys, but these materials also present difficulty in machining. Excessive tool wear and high tooling costs of diamond tools makes the cost associated with machining of these composites very high. This paper is concerned with machining of high volume fraction long-fiber MMC’s, which has seldom been studied. The composite material considered for this study is an Al-2%Cu aluminum matrix composite reinforced with 62% by volume fraction alumina fibers (Al-2%Cu/Al2O3). Laser-machining is utilized to improve the tool life and the material removal rate while minimizing the sub-surface damage. The effectiveness of the laser-assisted machining process is studied by measuring the cutting forces, specific cutting energy, surface roughness, sub-surface damage and tool wear under various material removal temperatures. A multi-phase finite element model is developed in ABAQUS/Standard to identify and assist in selection of cutting parameters such as; tool rake angle, cutting speed and material removal temperature. The multi-phase model is also successful in predicting the damage depth on machining. The optimum material removal temperature is established as 300°C at a cutting speed of 30 m/min. LAM provides a 65% reduction in the surface roughness, specific cutting energy, the tool wear rate and minimum sub-surface damage over conventional machining using the same cutting conditions.

Abstract:
Composite materials provide distinctive advantages in manufacture of advanced products because of attractive features such as high strength and light weight, but on the other hand machining of composite materials is difficult to carry out due to the anisotropic and non-homogeneous structure of composites and to the high abrasiveness of their reinforcing constituents. This typically results in damage being introduced into the workpiece and in very rapid wear development in the cutting tool. Conventional machining process such as drilling can be applied to composite materials, provided proper tool design and operating conditions are adopted. In this paper, A genetic algorithm (GA) based optimization procedure has been developed to optimize two factors, material removal rate; and delamination factor, using multi-objective function model with a weighted approach for the productivity, and superficial quality. An a posteriori approach was used to obtain a set of optimal solutions. An application sample was developed and its results were analyzed for several different production conditions. Finally, the obtained outcomes were arranged in graphical form and analyzed to make the proper decision for different process preferences. This paper also remarks the advantages of multi-objective optimization approach over the single-objective one.

Abstract:
Abstract Hybrid composite stacks are multi-material laminates which find extensive applications in industries such as aerospace, automobile, and electronics. Most hybrid composites consist of multi-layer fiber composites, and metal sheets stacked together. These composite stacks have excellent physical and mechanical properties, including high strength, high hardness, high stiffness, excellent fatigue resistance, and low thermal expansion. Composite stacks are fabricated to near net shape; additional machining operations are often required for several applications, primarily in the aerospace industry. The most frequent machining operation is high-speed cold saw cutting of these hybrid stacks within specified tolerances. During the cutting process, the cutting fluids play a significant role by reducing the cutting temperature and cutting forces, thereby increasing the surface quality finish of the hybrid composite stack. However, most of the cutting fluids pose environmental and health risks. Recently, researchers have been exploring the possibilities of using MQL to overcome the adverse effects of traditional cutting fluids. This research investigates MQL based cutting of hybrid composite stacks using different types of nanoparticle-enhanced vegetable oils. Specifically, the nanoparticles of choice that have found extensive popularity within the booming nano industry: Al2O3, Al(s), Ni(s), and Carbon Nanotubes (SWCNTs). For this study, CFRP/Al and CFRP/Ti composite stacks are used as the substrates. The effects of critical process parameters on the quality, surface roughness, and interface delamination of the composite materials are studied. The process parameters under consideration include the type of vegetable oils utilized, namely, jojoba and castor oil, the nanoparticle-enhancement effects, and the construction of the hybrid composite stack. From the results of this study, it is found that the chemistry between the MQL of choice and the dispersion of the nanoparticles is of critical importance. The results of this study are expected to open new possibilities for eco-friendly and cost-effective methods for cold saw cutting advanced engineering materials.

Abstract:
This study examines the performance of a new class of wear-resistant but economical cutting tools produced by varying the binder composition of standard cemented carbide composites. By replacing some or all of the cobalt binder with rhenium and nickel-based superalloy, a stronger composite tool results, potentially capable of machining heat-resistant superalloys at significantly higher cutting speeds. Sample tools with alternative binder were produced and compared to standard tools bound with cobalt only. Turning experiments on Inconel 718 were run to evaluate wear resistance and tool life for several grades. The experimentation also examined the effects of varying the relative proportions of each binder constituent as well as the overall binder percentage in the composite. Results show a clear advantage of the alternative binder tools as evidenced by a 150% increase in tool life or the equivalent of an 18% increase in cutting speed. Although increasing amounts of rhenium in the binder show a positive effect on performance, the effects of superalloy and overall binder % are inconclusive.

Abstract:
Abstract Composite materials are the advanced materials which are widely used in manufacturing industries. The most commonly used composite materials are metal matrix composites. Due to the presence of abrasive reinforcing particles, traditional machining of these causes severe tool wear and hence reduces the life of cutting tool. Wire electrical discharge machining (WEDM) is quite successful for machining of metal matrix composites. Wire Electrical Discharge machining is a specialized thermal machining process capable of accurately machining parts of hard materials with complex shapes. One of the main research fields in WEDM is related to the improvement of the process productivity by avoiding wire breakage. Wire electrodes used in WEDM are the core of the system. In this study the effect of different wire electrode materials on electrode wear and surface finish for wire electrical discharge machining of metal matrix composite material were investigated. The experiments were conducted under the following process parameters viz., pulse-on time, pulse-off time, wire feed speed and current. For the experiment the aluminium 6061 alloy with 0%, 5%, and 10% of silicon carbide (SiC) reinforcement material was used. To conduct the experiment CNC wire EDM machine with two different wires viz., molybdenum and brass wire was used. Experimental results indicate that for better surface finish of Al6061 alloy, the brass wire is more suitable. The use of brass wire as electrode material leads to significant reduction in electrode wear in machining of Al-5%SiC and Al-10%SiC composite materials compare to molybdenum wire. Increasing percentage of silicon carbide in aluminium 6061 alloy increases the variation in surface finish and electrode wear. Wire wear rate of both brass and molybdenum wire is increased with increase in percentage of silicon carbide.

Abstract:
The machinability of carbon nanotube (CNT)-reinforced polymer composites is studied as a function of CNT loading, in light of the trends seen in their material properties. To this end, the thermo-mechanical properties of CNT composites with different loadings of CNTs are characterized. Micro endmilling experiments are also conducted on all the materials under investigation. Chip morphology, burr width, surface roughness and cutting forces are used as the machinability measures to compare the composites. For composites with lower loadings of CNTs (1.75% by weight), the visco-elastic/plastic deformation of the polymer phase plays a significant role during machining, whereas, at loadings ≥ 5% by weight, the CNT distribution and interface effects dictate the machining response of the composite. The ductile-to-brittle transition and reduction in fracture strength that occurs with an increase in CNT loading, results in reduced minimum chip thickness values, burr dimensions and cutting forces in the CNT composite. The increase in thermal conductivity with the increase in CNT loading, results in reduced number of adiabatic shear bands being observed on the chips and reduced thermal softening effects at high cutting velocities. Thus, overall the increase in CNT loading improves the machinability of the composite.

Abstract:
A multi-phase and a continuum based finite element model using the commercial finite element package ABAQUS is developed for simulating the orthogonal machining of composite materials. The materials considered for this study are a glass fiber reinforced epoxy composite and a ceramic matrix composite. The effect of varying the fiber orientation and tool rake angle on the cutting force, temperature distribution and damage during machining are considered. In the multi-phase approach the fiber and matrix are modeled as continuum elements with isotropic properties separated by an interfacial layer while the tool is modeled as a rigid body. The cohesive zone modeling approach is used for the interfacial layer. Bulk deformation and shear failure is considered in the fiber and matrix while the traction separation in the cohesive zone is used to ascertain the extent of delamination below the work surface. For validation purposes simulation results of the multi-phase approach are compared with experimental measurements. Parametric studies are conducted utilizing the equivalent homogenous (EHM) material model. The EHM simplifies the composite material into an anisotropic but locally homogenous material. External heating effect on the workpiece is considered in the EHM model to include preliminary results on Laser Assisted Machining. The model is successful in predicting cutting forces, temperature distribution entry and exit damage with respect to the fiber orientation.

Abstract:
Metal matrix composites (MMC) are difficult to cut materials, and yet only diamond tools have been successfully utilized for such machining applications. Wear of diamond-coated tools is characterized by catastrophic coating failure (peeling off) due to the adhered work materials at the flank wear-land surface and the high stress developed at the coating-substrate interface, associated with high temperatures, because of very different thermal expansion coefficients. Temperature reductions, therefore, may delay the onset of the coating failure and offer tool life extension. A passive heat-dissipation device, heat-pipe, has been tested for cutting temperature reductions in MMC machining. Though it is intuitive that heat pipes may enhance heat transfer and plausibly reduce the tool temperatures, heat pipes may also increase heat partitioning into the tool, and complicate its effects on the heat removal and temperature reduction efficiency. This paper reports aluminum composite machining by diamond-coated tools and investigates the heat-pipe effects on tool temperature reductions. Numerical simulation of heat conduction in the cutting tool system was performed to evaluate cutting tool temperatures without and with a heat-pipe. A 3-D thermal model of the cutting tool system including coating, insert substrate, and tool holder was established. The heat source was characterized as a heat flux, a portion of the frictional heat flux at the rake face, over the chip-tool contact area. To determine the heat-partition coefficient, a separate 2-D chip model was established with a heat flux, balanced the total rake-face heat flux, over the contact and moving with the chip speed. With the tool and chip thermal models and by matching the average temperature at the tool-chip contact of the two models, the heat partition coefficient can be numerically determined. The model has been used to evaluate how the heat-pipe modifies the cutting tool temperatures. Applying heat-pipe cooling inevitably increases the heat partition into the tool despite the enhanced heat dissipation. However, the heat pipe still effectively reduces the tool-chip contact temperatures, depending upon machining conditions. Cutting tool temperatures have also been measured in machining using thermocouples. The simulation results reasonably agree with the experimental measurements.

Abstract:
On this Phase I SBIR project, Creare’s overall objective was to develop and transition a technology that will increase cutting tool life and reduce overall production costs of machining ceramic matrix composite (CMC) materials. We successfully demonstrated the feasibility of machining CMC materials using the Laser-Assisted Machining (LAM) approach, which utilizes a laser to preheat a thin layer of the CMC material prior to its removal using conventional machine tools. In particular, we demonstrated that the cutting forces were reduced by as much as 40% compared to conventional machining processes. This reduction enables increased processing speeds which decrease cycle times and overall processing costs. Additionally, we developed and validated a comprehensive thermal model for the edge machining of CMCs. When combined with the experimental results, the temperatures near the material removal interface for the optimal LAM condition were predicted.
