Abstract:

This paper presents a rage of variable machining factors which influence substantially friction directly or by the abrasive media wear developed in the cutting zone. Abrasive flow machining is method of machining surfaces of complex holes and curved surface. In the case of traditional stream treatment methods abrasive (AFM) it is difficult to obtain a uniform roughness radial decomposition during polishing complicated openings, which results from uneven distribution of abrasive forces. The group of direct factors include the work piece materials and abrasive media, changes in the fluid pressure, number of flow cycles, the medium flow frequency. In addition, it was proposed modifications in the amount and size of grains abrasives filling the abrasive medium to increase the value of the grain pressure force on the surface to be processed and obtained an even surface of complex holes in the process AFM processing. Special attention was paid to the abrasive media wear evolution and its pronounced effect on changes of the contact conditions. The experiment results also confirm that the rise in the medium flow frequency during the process will not affect the roughness changes work piece surface.

Abstract:

Abrasive Flow Machining (AFM) is a nontraditional finishing process that deburrs and polishes by forcing an abrasive-laden viscoelastic polymer across the workpiece surface. Current applications include improvement in air and fluid flow for cylinder heads, intake manifold runners and injector nozzles. Present manufacturing methods include a series of flow test and AFM operations which require significant material handling and operator adjustment. An effective on-line monitoring and adaptive control system for AFM is needed. This paper reports on the development of an acoustic emission (AE) based monitoring strategy and the AE characteristics of abrasive flow machining. Initial results showed AE to be a viable sensing method for determining the performance characteristics of AFM for simple extrusion passage geometries in a selected part design. The root mean square (RMS) voltage of the AE signal was mainly determined by the metal removal and related AFM process parameters. Frequency decomposition of the AE signals revealed distinct frequency bands which have been related to the different material removal modes in AFM and to the workpiece material. Research was also performed on the application of AFM to finish orifices of varying sizes. Extremely high correlations were found between the AE signal and both the orifice diameter and the volumetric flow rate. Work is continuing with the equipment manufacturer and key industrial users to apply the monitoring strategy as part of a prototype Flow Control AFM.

Abstract:

Abrasive flow machining (AFM), also known as extrude honing, is a method of smoothing and polishing internal surfaces and producing controlled radii. A one-way or two-way flow of an abrasive media is extruded through a work piece, smoothing and finishing rough surfaces. In one-way systems, we flow the media through the work piece, then it exits from the part. In two-way flow, two vertically opposed cylinders flow the abrasive media back and forth. In the paper, the various types of abrasive laden polymer media, their work piece applications as well as the compatibility with the abrasives used is explained. The properties of the polymer used in AFM are compared and the best combination of polymer, abrasive and hydrocarbon oil is selected. Apart from polymer properties, the media flow equations, abrasive wear and forces is also studied.

Abstract:

The characteristics of the products’ treatment by the abrasive flow machining (AFM) makes it an appropriate method of finishing the surface with complex geometry, e.g. holes or channels. Traditional methods of machining cause difficulties in obtaining a homogeneous roughness during finishing complicated shapes due to uneven distribution of abrasive forces. Due to the high price of abrasive media, not every user can afford for using it for processing. In the frame of the research, the novelty abrasive media has been developed to improve the surface roughness of the elements of polymer products. The use of viscoelastic polymers as a media of flow abrasive machining was discussed. Moreover, it is suggested to modify the quantity and size of abrasive grains filling the abrasive media in order to increase the value of the grain pressure force on the machined surface and to obtain an even surface of complex holes in AFM process.

Abstract:

Finishing operations in the metal working industry represent a critical and expensive phase of the overall production process. A new process called Abrasive Flow Machining (AFM) promises to provide the accuracy, efficiency, economy, and the possibility of effective automation needed by the manufacturing community. The AFM process is still in its infancy in many respects. The process mechanism, parametric relationships, surface integrity, process control issues have not been effectively addressed. This paper presents preliminary results of an investigation into some aspects of the AFM process performance, surface characterization, and process modeling. The effect of process input parameters (such as media viscosity, extrusion pressure, and number of cycles) on the process performance parameters (metal removal rate and surface finish) are discussed. A stochastic modeling and analysis technique called Data Dependent Systems (DDS) has been used to study AFM generated surface. The Green’s function of the AFM surface profile models provides a “characteristic shape” that is the superimposition of two exponentials. The analysis of autocovariance of the surface profile data also indicates the presence of two real roots. The pseudo-frequencies associated with these two real roots have been linked to the path of the abrasive grains and to the cutting edges of the grain. Furthermore, expressions have been proposed for estimating the abrasive grain wear and the number of grains actively involved in cutting with a view towards developing indicators of media batch life. A brief introduction to the AFM process and related research is also included in this paper.

Abstract. Abrasive flow machining (AFM) is an effective method that uses the flow of a pressurized abrasive media for removing workpiece material. It is used to deburring, polishing or radiusing, etc. In this paper, the effect that AFM process on the surface of the helical gear is investigated. Then, the distribution of the velocities, shear rates and shear forces of the abrasive flow on the helical gear surface is obtained by CFD module of the COMSOL Multiphysics software. The simulation results show that the abrasive grains near the addendum, tooth surface and tooth root can be subjected to corresponding shear stress. Experimental results indicated that the surface roughness Ra of the left tooth surface, right tooth surface and addendum before processing 1.429um, 1.108um and 2.732um dropped after processing 0.228um, 0.216um and 1.754um. All burrs at the intersection between tooth surface and end surface has been cleared, the surface quality of the helical gear has been improved. Therefore, AFM method can improve the surface quality of the helical gear effectively.

Abstract:

Abstract The surface roughness of a part is the most important parameter in view of tribological applications and it also affects the working life of the part during application. The abrasive flow machining (AFM) process is an advanced non-conventional finishing process, used to deburr, polish, and to remove the recast layer from the surface as well as at the edges of the components. In AFM viscoelastic media is used to finish the workpiece with close dimensional tolerance and precision. The viscoelastic media used in the AFM process is laden with abrasive particles. In the present work, a finite element analysis of viscoelastic abrasive media is performed considering the AFM process. A mixture of polyborosiloxane and silicon carbide is used as viscoelastic abrasive media and the AFM process is modeled using ANSYS Polyflow. In the analysis, the flow of viscoelastic abrasive media is assumed to follow the Maxwell model of viscoelastic fluid. The simulations were performed for varying the extrusion pressure for the finishing of an internal cylindrical surface. The results of the simulations were validated with the experimental observation and found in good agreement.

Wear properties of mild steel are considerably affected by the process parameters of AFM.The effect of extrusion pressure, abrasive concentration and abrasive size during AFM on wear performance were investigated using a reciprocating wear testing machine.

Abstract:

Abrasive medium plays an important role in the application of abrasive flow machining (AFM), a process that finishes complex internal and external geometries. A new abrasive medium needs to be fabricated due to a lack of literature on it. In this work, a new abrasive medium was fabricated by using styrene butadiene rubber (SBR) as carrier and DF-101S was used to study its characterization. Results showed that new abrasive medium with good fluidity and temperature stability was obtained. Processing experiments have also been carried out by using new abrasive medium and MLLD60, and ZYGO was used to study the surface characteristics of the work-piece. Experimental results indicate that the new abrasive medium is applicable to AFM process.

Abstract:

This study attempts to determine how AFM affects the polishing of complex hole to achieve a smooth surface by examining WEDM efficiency when cutting a complex hole for various degrees of surface roughness. This research showed the complex holes with the chain shape of the mold steel were cut by WEDM first, however, there were three kinds of the average roughness in the hole surface (1.3μm Ra, 0.8μm Ra and 0.4μm Ra) when three cutting processes of WEDM were used to manufacture the complex holes. Then silicon carbon (SiC) or diamond abrasive (DA) mixed with the silicone gel was utilized as abrasive medium to polish these holes, machining processes were finished when the surface roughness of the complex holes were decreased to the steady values in AFM. Finally, three surface roughness of the complex hole in the different positions would be used to judge the finishing surface was smooth or not, and machining time of the complex holes between WEDM and AFM was utilized to evaluate the efficiencies of these process when the surface of the complex holes had uniform roughness after machining. The results showed that surface roughness would not easily uniform after AFM until the cutting roughness, produced by WEDM, reduced to 0.4μm Ra when SiC was utilized as abrasive. But the surface roughness would uniform after AFM only the cutting roughness reached 0.8μm Ra when DA was used as abrasive, and the total machined time to a uniform roughness (WEDM+AFM) was the less (45 minutes) when the cutting roughness with 0.8μm Ra was utilized as original surface roughness.

Abstract:

Since only uni-direction motion is produced by traditional abrasive flow machining (AFM), so the polishing effects of the inner hole is not easy to achieve uniform roughness of the whole surface after polishing. Therefore, in this study, a rotating device with a DC servo motor was set up in the AFM to increase the tangential forces on the machining surface, and therefore, improve the uniform surface roughness and polishing efficiency. The rotating device was designed by a group of transmission gear set and a DC servo motor to create a rotational finishing path for the abrasive medium. The rotational motion of an abrasive can create different tangential forces on the working surface, inducing a more complex polishing path than that of traditional AFM. In addition to rotational speed, a servo motor can also change rotation directions in one working process, causing an abrasive medium to create many irregular finishing paths in the AFM. The experimental results showed that the surface roughness of the workpiece was significantly decreased with an increase in the rotational speed. Additionally, the results also showed that the surface roughness (SR) of the inner hole decreased from 0.61 μm Ra to 0.082 μm Ra after 20 machining cycles, the surface roughness improvement rate reached 87% at 15 rpm rotational speed, by applying a 1.5:1 silicone gel/abrasive concentration ratio and #60 abrasive mesh in the experiments. This study created excellent polishing efficiency by using a servo rotational device with AFM to produce good surface quality.

Abstract:

Trends like lightweight construction and functional integration lead to more and more complex workpieces. Often, these workpieces must be finished after machining. Especially inner contours are difficult to finish. Hence, only a few manufacturing techniques are suitable for deburring, edge rounding and polishing of inner contours. An appropriate solution is abrasive flow machining (AFM), in which a highly viscous fluid with abrasive grains is used. Despite the wide usage of AFM in industry, the knowledge about the fundamentals of abrasive flow machining processes is limited. After elaborated test series new findings concerning the surface integrity are presented in this paper. This is done in terms of the regressive development of the surface roughness on the one hand and in terms of the generated edge rounding on the other hand. In this context, it is found that there is a factor of approximately 16 between the chipped material at the edge and the chipped material at the surface. This factor is nearly constant during the processing time. Finally, using the results of the studies, the correlation between the processing parameters, surface roughness, edge rounding, and material removal rate can be characterized. Moreover, these new findings can be transferred to a comprehensive process model, which is the basis for a reliable process simulation. Owing to this progress, predictions of the processing results of AFM will be possible.

Abstract:

Al/SiCp-MMC’s find their use in engineering and structural components but their machining particularly finishing is a challenge for manufacturing engineers due to their heterogonous nature having abrasive particles randomly distributed and oriented in the matrix material. An abrasive flow machining (AFM) set up has been designed and fabricated with an indigenously developed alternative media to finish the internal cylindrical surfaces of Al/SiCp- MMC components. Work-pieces were prepared by lathe operations after stir casting Al/SiC-MMC, 25 mm diameter bar of 0%, 5%, 10% and 15% SiC by weight. The influence of AFM process parameters e.g. abrasive mesh size, number of cycles, extrusion pressure, abrasive concentration and AFM media viscosity grade on average surface finish improvement, Ra and material removal, MR, mg have been analyzed. The Scanning Electron Microscopy (SEM) study also reveals the improvement in surface finish of these MMC’s.

Abstract:

Surface finish and Manufacturing process has a prominent role in the fatigue life of a machine component. Fatigue strength of a material generally increases with the surface finish. But the super finishing process like electro polishing reduces the fatigue strength of the material. In Abrasive flow machining it is found that surface finish and fatigue strength always increasing. In Abrasive flow machining the fatigue strength is mainly governed by the process variables extrusion pressure, abrasive concentration and mesh size. This research studies the influence of the process variables on the fatigue strength of the material. In this study an approximate surface finish of 4μm is obtained after AFM. The effect of three process variables on the response function selected, fatigue strength, were studied. A statistical 23full factorial experimental technique is used to find out the main effect, interaction effect and contribution of each variable on fatigue strength. The instron machine is used to find out the number of cycles to failure of the material. The fatigue strength is obtained with S-N curve analysis.

Abstract:

In order to reduce the cost, improve the surface of workpiece machined by AFM and make out reasonable technological parameters of AFM, AFM theory model has been developed in the present work. The process parameters such as pressure, piston velocity, temperature and viscosity impacting on the workpiece surface quality have been researched. Firstly, the properties parameters of abrasive media such as viscous have been figured out with formulas based on the characters of abrasive media. And then the force between abrasive near to the workpiece surface and workpiece has been modeled with fluidics equations and dynamics equations. However, different parameter value leads to different force and different force has different surface quality (Ra) of workpiece. The calculation result is similar to the experiment result to some extent. Obviously, this model is helpful to establish the reasonable process parameters.

Abstract:

Abrasive flow machining (AFM) is one of the most promising technologies for internal finishing and de-burring for features with complex geometry. This study investigates the effect of media degradation on finishing characteristics achieved using the AFM process. A total of 50 experiments, using Inconel 718 cylindrical coupons machined by Wire-Electron Discharge Machining (WEDM), were conducted employing the same process conditions while using a single batch of AFM media. Experimental results indicate that media degradation has minor influence on surface roughness, but more significant influence on material removal and media flow rate. Material removal decreases exponentially with increasing cumulative media flow volume despite media flow rate increasing. There is a linear correlation between material removal and media flow rate. As a result, material removal can be estimated from media flow rate which can be monitored easily.

Abstract:

Abrasive flow machining (AFM) is considered as one of the best-suited techniques for surface finishing of laser powder bed fused (LPBF) parts. In order to determine the AFM-related allowances to be applied during the design of LPBF parts, a numerical tool allowing to predict the material removal and the surface roughness of these parts as a function of the AFM conditions is developed. This numerical tool is based on the use of a simplified viscoelastic non-Newtonian medium flow model and calibrated using specially designed artifacts containing four planar surfaces with different surface roughnesses to account for the build orientation dependence of the surface finish of LPBF parts. The model calibration allows the determination of the abrasive medium-polished part slip coefficient, the fluid relaxation time and the abrading (Preston) coefficient, as well as of the surface roughness evolution as a function of the material removal. For model validation, LPBF parts printed from the same material as the calibration artifacts, but having a relatively complex tubular geometry, were polished using the same abrasive medium. The average discrepancy between the calculated and experimental material removal and surface roughness values did not exceed 25%, which is deemed acceptable for real-case applications. A practical application of the numerical tool developed was demonstrated using the predicted AFM allowances for the generation of a compensated computer-aided design (CAD) model of the part to be printed.

Abstract:

In this paper we discuss the temperature dependence and its effect on surface roughness. In abrasive flow machining (AFM) process the temperature of media rises drastically due to procedure of being sheared. To examine the effect of media temperature on surface roughness, an experiment system with the functions of controlling, measuring and recording temperature is set up. The variable trend of media temperature is revealed during AFM. Experiments are performed at different temperatures. Experimental results show that the media at high temperature results in less improvement in surface roughness. Therefore the media can have good machining performance in the first few cycles and the media temperature rise rapidly. Finally we conclude that the best workable temperature should be below 25 °C during the AFM.

Abstract:

Considering the demand of precision in mould structural surface polishing method, a new method based on soft abrasive flow machining(SAFM) was proposed, which was supposed to achieve polydirectional and multi-angle cutting acting on the surface of the workpiece by utilizing the irregular motion of both wear particles and the media in turbulence flow. Thus as the monodirectional marks on the machined surfaces was eliminated, the disadvantage in machining precision in conventional abrasive flow machining(AFM) method would be overcome. According to the particle distribution characteristics of SAFM, a two-phase dynamic model of abrasive flow oriented to SAFM combined with Discrete Phase Model(DPM) was built to analog simulation with the software Fluent. Sequently the mechanism of ultraprecision machining towards mould structural surface was analyzed briefly. Simulation results show that the abrasive efficiency along the flow passage can be influenced by the development of turbulence and the distribution of dispersed phase. Thus there a specific region can be obtained in the passage in which the abrasive efficiency is relatively stable.

Numerical investigations of the abrasive influence on material removal efficiency of the micro-hole for AFM process is conducted in this paper. A three-dimensional model is constructed for this process. The abrasive with various particles volume fraction and different micro-holes with various diameters are selected in this study. The simulation results show that the lower particle volume fraction may be in favour of the metal removal uniformity, but the processing time will be too long if too low fraction is selected.

Abstract:

Abrasive flow machining (AFM) is a simple and efficient method to remove recasting layers making by wire electrical discharge machining (WEDM). However, conventional AFM methods have difficulty achieving uniform roughness of an axial distribution in circular hole polishing due to limited unitary axial motion of abrasive media. Therefore, this work develops mechanism designs for different passageways to obtain multiple flowing paths of abrasive medium, whose flowing behavior enhances polishing effectiveness by increasing the abrasive surface area and radial shear forces. The motion of the abrasive medium is studied by utilizing different mold cores, which mold shapes include the circular, hollow and helical passageway. The optimum design of the passageways is then verified using CFD-ACE+ software, numerical results indicate that passageway with six helices performed better in the uniform surface roughness than others’ do. Experimental results show that roughness deviation of six helices passageway of approximately 0.100 m Ra is significantly better than those on a circular passageway of around 0.1760 m Ra. Additionally, the six helices passageway is also superior to circular passageway in reducing roughness improvement rate (RIR) by roughly 87% compared with RIR 67.7% for the circular passageway.

Abstract:

The abrasive flow machining (AFM) processes are ultra-precise finishing techniques widely used as finishing solutions for micro/nano finishing of inaccessible contours on difficult to machine components. The AFM processes use highly visco-elastic properties of the abrasive laden medium as a cutting tool for deburring, edge rounding and polishing the surface. Due to the design of workpiece holder and hybridization of basic AFM, the complex shear modulus of the abrasive laden medium can locally be influenced and thus a targeted removal of material from workpiece can be achieved, as a result, there was improved performance, productivity, surface integrity, and texture. This article addresses the detailed classification of AFM processes based on the use of different energy and tooling and highlights the critical outcomes in each category. The objective of this article is to review and summarize various process parameters of AFM processes like extrusion pressure, medium flow volume, medium flow rate, number of cycle, viscosity, workpiece geometry, etc. and their effects on roughness value and material removal rate. Key capabilities and noted findings concerning various AFM processes in addition to their applications and future challenges are also discussed in this paper.

Abstract:

Abrasive flow machining is a suitable technique for surface polishing due to its rheological characteristics, however, it's difficult to achieve uniform roughness for polished surfaces as the material removal mechanism is still ambiguous. In this paper the viscoelastic properties of abrasive flow media are incorporated to explore the phenomena of inconsistent material removal in the AFM polishing process, where the material removal near the edges is obviously higher than that in the middle along the flow direction. The rheological parameters of the viscoelastic constitutive model adopted are varied to study the polishing effectiveness under different process conditions. The results of numerical analysis reveal that there exist distinct differences of viscoelastic stress fields between the edges and the middle regions, which leads to the material removal near the edges is higher than that in the middle. It could be concluded that the viscoelastic properties of abrasive media play the dominant role for the inconsistent material removal in abrasive flow machining process.

Abstract:

In order to grasp the microcosmic mechanism of abrasive flow machining (AFM), find out the real law of grain cutting workpiece surface, make out a reasonable process parameters and improve the abrasive flow processing efficiency. The process of grain (near to workpiece surface, called as active grains) cutting workpieces material has been analyzed and the cutting force model has been established in present work. Firstly, at the beginning of the present work, the general process of grain cutting, wearing or deburring workpiece surface has been researched. Theoretical analysis shows that the cutting force not only derives from static force, such as abrasive medium viscoelasticity and grain squeezing, but also dynamic force, such as grain impacting load on the workpiece surface. In ordering to prove the dynamic force exists, one or two main dynamic process parameters (such as abrasive viscosity, extrusion pressure, piston velocity) are chosen, dynamic force is most sensitive to the variation of which, meantime, static force is not, and then the effects of main dynamic process parameters on cutting force value have been compared with the effects of others process parameters by several experiments in the present work. The experimental results show that with the same proportion of variation of process parameters, the change in cutting force (mainly axial cutting force) consists with theoretical results very well in some degree.

Abstract:

Burrs form due to the plastic deformation of materials during machining processes, such as milling and drilling. Deburring can be very difficult when the burrs are not easily accessible for removal. In this study, abrasive flow machining (AFM) was adopted for deburring the edges of milling specimens. Based on the experimental observations on AL6061 specimens, the deburring performance was characterized in terms of flow speed, the local curvature of the streamline near the burr edge, and shear stress. A new objective function that can predict the extent of deburring is proposed based on these characteristics and validated through milling burr edge erosion tests by abrasive flow. Based on the assumption that the flow component is tangential to the burr edge has relatively little contribution to the edge erosion, an attempt was made for the application of the new objective function to the three-dimensional burr edge formed by two intersecting holes drilled with offset. The deburring test results and predictions from three-dimensional computational fluid dynamics’ (CFD) simulations were in reasonable agreement.

Implementing non-conventional finishing methods in the aircraft industry by the abrasive flow machining (AFM) process depends on the production quality at optimal conditions. The optimal set of the process variables in metal-matrix-composite (MMC) for a varying reinforcement percentage removes the obstructions and errors in the AFM process. In order to achieve this objective, the resultant output functions of the overall process using every clustering level of variables in a model are configured by using genetic programming (GP). These functions forecast the data to vary the percent of silicon carbide particles (particles without experimentation obtaining the output functions for material removing rates and surface roughness changes of Al-MMCs machined with the AFM process by using GP. The obtained genetic optimal global models are simulated and, the results show a higher degree of accuracy up to 99.97% as compared to the other modeling techniques.

Abstract:

Abrasive flow machining (AFM) is a non-traditional machining process used since the mid-1960s, which utilizes a mixture of polyborosiloxane and abrasive grit additions extruded across surfaces and edges and through component cavities. The machining mechanism of this process is still only partially understood due to its complex nature, and the present work undertook to investigate the relationship between the rheological characteristics of several mixtures and their associated machining parameters. This paper addresses those rheological characteristics of the various mixtures used in the present work. Experiments were conducted using low viscosity (LV), medium viscosity (MV) and high viscosity (HV) polyborosiloxane base media, in conjunction with silicon carbide abrasive grit of 60 and 100 mesh size, the ratios of the grit to base polymer used being 0, 1 and 2. The test pieces used were mild steel dies and the equipment used to conduct the experiments was an Extrude Hone mark 7 A machine. The results have shown that progression from low to high viscosity base medium produces a reduction in the temperature rise (for example from 32 to 10°C over 30 cycles) as well as an increase in both the average pressure drop across the die (for example from 1700 to 2674 kPa over 30 cycles) and the processing time (for example from 28 to 406 s over 30 cycles). In addition, the temperature of the medium is seen to be an important variable in the AFM process due to its effects on viscosity. Furthermore, as the usage of a medium increases the viscosity and pressure drop across the die increase.

Abstract:

Purpose Internal channels produced by selective laser melting (SLM) have rough surfaces that require post-processing. The purpose of this paper is to develop an empirical model for predicting the material removal and surface roughness (SR) of SLM-manufactured channels owing to abrasive flow machining (AFM). Design/methodology/approach A rheological model was developed to simulate the viscosity and power-law index of an AFM medium. To simulate the pressure distribution and velocity in the SLM channels, the fluid behavior and SR in the channels were simulated by using computational fluid dynamics. The results of this simulation were then applied to create an empirical model that can be used to predict the SR and material removal thickness. To verify this empirical model, it was applied to an actual part fabricated by SLM. The results were compared with the measurements of the SR and channel diameter subsequent to AFM. Findings The proposed model exhibits maximum deviation between the model and the measurement of −1.1% for the down-skin SR, −0.2% for the up-skin SR and −0.1% for material removal thickness. Practical implications The results of this study show that the proposed model can avoid expensive iterative tests to determine whether a given channel design leads to the desired SR after smoothing by AFM. Therefore, this model helps to design an AFM-ready channel geometry. Originality/value In this paper, a quantitatively validated AFM model was proposed for complex SLM channels with varying orientation angles.

Abstract:

A crucial and costly step in the whole manufacturing process is the precision and super finishing procedure. A step of final finishing is involved in the production of precision components. It accounts for a respectable portion of the cost of production overall, is mostly uncontrolled, and requires a lot of manpower. Abrasive finish methods are being developed to address issues including high direct costs and the production of precision components with particular characteristics for finishing inaccessible places. A vast number of cutting blades with arbitrary orientation and shape are used in the abrasive finishing process. Due to their ability to complete a variety of form geometries with the appropriate dimensional accuracy and surface polish, abrasive fine procedures are often used. The unconventional finishing method known as AFM (abrasive flow machining) presses abrasive viscoelastic polymer on the surface of work piece. Al7075/SiC NMMCs’ internal rounded and hollow surfaces are completed using an AFM trial procedure that is constructed and designed in conjunction with specially produced medium. Workpieces are created using a lathe shortly after stir casting metal matrix nano composites with cross sections of 25 mm in diameter and containing 1 percent,1 ,2,3,4 nano-Sic (50 nm) by weight. Extrusion pressure abrasive particle grain size number of cycles were evaluated for their surface roughness (Ra) than material removal (MR), respectively. The evaluation of the material’s qualities, such as density, hardness, and tensile strength The improvement in the surface completeness of these NMMCs is further shown by the scanning Microscopy OM, EDS SEM, and XED analyses.

Abstract:

Recent advances in technology and refinement of available computational resources paved the way for the extensive use of computers to model and simulate complex real-world problems difficult to solve analytically. The appeal of simulations lies in the ability to predict the significance of a change to the system under study. The simulated results can be of great benefit in predicting various behaviors, such as the wind pattern in a particular region, the ability of a material to withstand a dynamic load, or even the behavior of a workpiece under a particular type of machining. This paper deals with the mathematical modeling and simulation techniques used in abrasive-based machining processes such as abrasive flow machining (AFM), magnetic-based finishing processes, i.e., magnetic abrasive finishing (MAF) process, magnetorheological finishing (MRF) process, and ball-end type magnetorheological finishing process (BEMRF). The paper also aims to highlight the advances and obstacles associated with these techniques and their applications in flow machining. This study contributes the better understanding by examining the available modeling and simulation techniques such as Molecular Dynamic Simulation (MDS), Computational Fluid Dynamics (CFD), Finite Element Method (FEM), Discrete Element Method (DEM), Multivariable Regression Analysis (MVRA), Artificial Neural Network (ANN), Response Surface Analysis (RSA), Stochastic Modeling and Simulation by Data Dependent System (DDS). Among these methods, CFD and FEM can be performed with the available commercial software, while DEM and MDS performed using the computer programming-based platform, i.e., “LAMMPS Molecular Dynamics Simulator,” or C, C++, or Python programming, and these methods seem more promising techniques for modeling and simulation of loose abrasive-based machining processes. The other four methods (MVRA, ANN, RSA, and DDS) are experimental and based on statistical approaches that can be used for mathematical modeling of loose abrasive-based machining processes. Additionally, it suggests areas for further investigation and offers a priceless bibliography of earlier studies on the modeling and simulation techniques for abrasive-based machining processes. Researchers studying mathematical modeling of various micro- and nanofinishing techniques for different applications may find this review article to be of great help.
