Resumen

The finishing characteristics of mechanically alloyed magnetic abrasives used in cylindrical magnetic abrasive finishing (MAF) are presented in this study. Mechanical alloying is a solid state powder processing technique, where the powder particles are subjected to impact by the balls in a high energy ball mill or attritor at room temperature. After the process, fine magnetic abrasives are obtained in which the abrasive particles are attached to the base metal matrix without any bonding material. The magnetic particle used in the magnetic abrasive production is iron powder and the abrasive is aluminium oxide. Magnetic abrasives play the role of cutting tools in MAF, which is emerging as an important non-conventional machining process. The experiments performed on stainless steel tubes examine the effects of varying the quantity of magnetic abrasives, magnetic flux density, speed of rotation of the workpiece and amount of lubricant. The surface roughness measurements demonstrate the effects of the abrasive behaviour on the surface modification. The surface roughness was analysed in terms of percentage improvement in surface finish (PISF). The obtained maximum PISF was 40 % and the minimum surface roughness was 0.63 μm Ra.

Resumen

Chromium oxide abrasive has been reported in the literature to provide efficient chemo-mechanical polishing action for silicon nitride ceramic. Since aluminum oxide and chromium oxide abrasives are nearly of the same hardness, magnetic float polishing tests were conducted on silicon nitride balls with these two abrasives to investigate mechanical versus chemo-mechanical aspects of polishing. Tests results show higher removal rates and smoother surface texture (with fewer pits) with chromium oxide abrasive compared to aluminum oxide abrasive. Formation of pits due to brittle fracture seems to be the more predominant mode of material removal with aluminum oxide abrasive than with chromium oxide abrasive. While there may be some mechanical action (abrasion) with chromium oxide abrasive initially, subsequent removal is believed to be due to chemo-mechanical action. This could be due to degeneration of the chromium oxide abrasive (both mechanical and chemical) during polishing. Various hypotheses for the material removal mechanism (both mechanical and chemo-mechanical) were considered. Based on that, the higher removal rates and smoother surface texture on the silicon nitride balls with chromium oxide abrasive in semifinish polishing is interpreted here as possibly due to chemo-mechanical action. Higher chemical stability of aluminum oxide abrasive (compared to chromium oxide abrasive) and the known role of chromium oxide as a catalyst for the oxidation of silicon nitride are some of the reasons attributed for this action.

Resumen

With the rapid development in the industry, applications of finished parts are increasing day by day. However, the surface finish of the parts fabricated by conventional processes could not readily meet the requirements of various applications. Therefore, post-processing is needed to further improve the surface quality. Magnetic abrasive machining uses a flexible magnetic abrasive brush to remove material from the workpiece surface at a controllable rate. This cutting tool sticks to the workpiece during finishing operation and exerts a small force on the surface. In magnetic abrasive machining, the cutting tool neither requires compensation nor dressing. In this paper, the internal finishing of aluminum pipes has been investigated in magnetic abrasive machining tests using silicon carbide-based glued magnetic abrasives. For evaluating the performance of these magnetic abrasives, experimental work according to the central composite design technique was carried out to finish the aluminum pipes. The results so obtained were analyzed to study the influence of process parameters like magnetic field strength, speed of workpiece, abrasive mesh size and quantity of magnetic abrasives on percentage improvement in surface finish and material removal rate. The analysis showed that magnetic field strength was the most effective parameter while finishing the aluminum pipe followed by the quantity of magnetic abrasives. The finishing at optimal condition resulted in a surface finish of 0.07 μm. Further, scanning electron microscopy of the surface before and after magnetic abrasive machining was taken to study the improvement in surface finish. HIGHLIGHTS Magnetic abrasive machining (MAM) of aluminum work specimens have been performed by SiC-based magnetic abrasives The central composite design has been used for planning and execution of experiments The surface finish and material removal rate of the machined work specimens have been analysed as a performance measure of MAM process The high value of improvement in surface finish and material removal rate at optimum machining conditions have been observed Scanning electron microscopy (SEM) has been employed to study the surface topography of machined surfaces GRAPHICAL ABSTRACT

Resumen

This study proposes a new wire magnetic abrasive finishing (WMAF) process for finishing 316L SUS wire using ecological magnetic abrasive tools. 316L SUS wire is a biomaterial that is generally used in medical applications (e.g., coronary stent, orthodontics, and implantation). In medical applications of this material, a smooth surface is commonly required. Therefore, a new WMAF process using ecological magnetic abrasive tools was developed to improve the surface quality and physical properties of this biomaterial. In this study, the WMAF process of 316L SUS wire is separated into two finishing processes: (i) WMAF with ecological magnetic abrasive tools, and (ii) WMAF with industrial magnetic abrasive tools. The ecological magnetic abrasive tools consist of cuttlefish bone abrasives, olive oil, electrolytic iron powder, and diamond abrasive paste. The finishing characteristics of the two types of abrasive tools were also explored for different input parameters (i.e., vibrating magnetic field and rotating magnetic field). The results show that ecological magnetic abrasive tools can improve the initial surface roughness of 316L SUS wire from 0.23 µm to 0.06 µm. It can be concluded that ecological magnetic abrasive tools can replace industrial magnetic abrasive tools.

Resumen

Titanium alloys are widely used in aerospace, the military industry, electronics, automotive fields, etc., due to their excellent properties such as low density, high strength, high-temperature resistance, and corrosion resistance. Many components need to be finished precisely after being cut in these applications. In order to achieve high-quality and high-efficiency finishing of titanium alloys, ultrasonic-assisted magnetic abrasive finishing (UAMAF) was introduced in this research. The machining performance for UAMAF of a titanium alloy was studied by experimentally comparing UAMAF and magnetic abrasive finishing (MAF). The results show that the cutting force of UAMAF can reach 2 to 4 times that of MAF, and it decreases rapidly with the increase in the machining gap due to the energy loss of ultrasonic impact in the transmission between magnetic abrasives. The surface roughness of UAMAF can reach about Ra 0.075 μm, which is reduced by about 59% compared with MAF. The main wear type of the magnetic abrasive is that the diamond grits fell off the magnetic abrasive in both UAMAF and MAF. The uniform wear of the magnetic abrasive is realized, and the utilization ratio of the magnetic abrasive is obviously improved in UAMAF.

Resumen

Due to the low efficiency of magnetic abrasive finishing and the difficulty in the making of magnetic abrasive grain, this article compares three different ways of its making, i.e. hot pressed sintering, spark plasma sintering (SPS) and ab-adhesive bonding sintering. SPS is found to have a higher cost, but it makes up the deficiency in magnetic abrasive grain made either by hot pressed sintering or by felt, with high abrasion resistance, processing efficiency and better processing performance.

Abstract Magnetic abrasive finishing (MAF) is a precise polishing method that the cutting tool is a group of magnetic abrasives, which the abrasion pressure is controlled by a magnetic filed. A limited amount of material will be removed by conducting a relative motion between the work surface and the abrasives, so as to obtain a mirrorlike finished surface. Owing to the magnetic field, the magnetic abrasives will gather to form a flexible magnetic brush. Thus the magnetic abrasives can move and polish along the profile of a complex surface, so the surface with complex shapes can be finished. Furthermore, the disturbances from the structure due to vibration or chatter will not affect the quality of the finished surface. The unbonded magnetic abrasive (UMA) used in this study is a mechanical mixture of ferromagnetic particles and abrasives. The finishing characteristics of UMA in cylindrical MAF are investigated, and then an application on improving the electrical discharge machined surfaces is performed. Experimental results demonstrate that the finishing characteristics of UMA are as good as those of sintered magnetic abrasives, which is much more expensive than UMA. The surface roughness of the SKD11 workpiece with HRC55 hardness can be improved from 0.25mm Ra to 0.042mm Ra after a few minutes of finishing. An improved MAF, which transfers the abrasion pressure to the abrasives through a sheet of unwoven cloth, can further improve the surface roughness of the workpiece to a level of 0.017mm Ra. Concerning the peripheral electrical discharge machined surfaces, MAF can remove the recast layer and the micro cracks easily, and a refined surface of 0.04mm Ra will be obtained. To elevate the finishing performance, an electrolytic magnetic abrasive finishing (EMAF), which is a compound polishing process by involving the traditional MAF and electrolysis, is developed. The passive film, whose hardness is lower than that of the original metal surface, is produced on the work surface, and is then removed by MAF during processing of EMAF. The finishing characteristics of EMAF are investigated, and then the results are compared with those of MAF concerning the cylindrical finishing of the SKD11 workpiece and the internal finishing of a circular pipe with AISI 304 stainless steel. Experimental results show that the finishing characteristics of EMAF are better than that of MAF. Despite what kind of surface is finished, EMAF yields a better surface roughness and higher material removal than MAF did. Especially in the case of the cylindrical finishing of SKD11, a mirrorlike finished surface of 0.017mm Ra can be produced from 0.178mm Ra after 5 minutes of finishing using EMAF. This study describes the principles of the process of MAF and EMAF, the finishing characteristics of surface roughness and material removal, and the associated mechanisms. Additionally, the theory, that the path of the electrolytic ions toward the anode surface is changed into a cycloid curve under the effect of the Lorentz force, and the forms of the passive film that is produced on the work surface in EMAF, are also described in detail. Some experiments on the only electrolytic process without MAF are performed to analyze the synergistic effect between MAF and electrolysis. Experimental results show that EMAF will produce rather large amount of extra material removal under proper process conditions due to the synergism of them. To determine the optimum process conditions for improving the surface finish and increasing the material removal in cylindrical EMAF, experiments using the Taguchi method and L18 orthogonal array are performed. Further, the significances of the control factors are identified with the assistance of analysis of variance (ANOVA).

Some stainless steel tube and aluminum alloy tube have many small holes, which are so slender that a conventional grinding tool is hardly inserted into the tube deeply, being impossible to machine down. A new high-efficiency technology of polishing method is created name magnetic abrasive polishing in which the suitable concentrative magnetic flux is performed in the inner working region of tube by N-S magnetic poles set in the outer side so that magnetic force as machining pressure acts upon magnetic abrasive particles to the internal surface. It is finishing performance using magnetic abrasives made of both iron and alumna. The iron particles generate finishing pressure by the magnetic field and magnetic abrasive also have a finishing effect on the inner surface of tubing. Magnetic abrasive finishing process is thought as one of possible methods for the automation of 3D mold surface finish in which is modified for applying to 2D free form surface and 3D curved surface. Magnetic abrasive polishing is used simple equipment and a few of workers and the possibility of precision edge finishing is confirmed. In the experiments showed that a work piece is finished smoothly 5 minutes from the un-machined surface roughness value of about Rmax 1.2μm to the machined value of Rmax 0.25μm

This research mainly had employed the gel magnetic abrasive finishing for grinding the surface of the mold steel. A magnetic abrasive cutting tool installed in the CNC machine was used to attract the magnetic abrasive gel. A flexible magnetic brush was produced when the magnetic field was applied in the gel. The surface roughness of the working pieces would be improved by this finishing method. In the experiment, the factors of the rotating speed, the abrasive size, the iron particle size, the abrasive concentration, and the grinding amount were used to improve the machining rate of the gel magnetic abrasive finishing. Based on the above research, the Taguchi method was adopted to find optimum parameters from the experiment. The roughness improved rate would reach to 92% after a 30 minute machining and the surface roughness of the working pieces would reduce to 0.083μm.

Abstract This research mainly employed the magnetic abrasive finishing method to process the stainless SUS304 material in face abrasive operations. The operations were demonstrated in the permanent magnetic field and the electrical magnetic polishing mechanism, it was installed in the CNC machining center. The operations were conducted using Taguchi experimental design, the effects among the parameters such as magnetic field, revolution, feed rate, gap, abrasive, and coolant, were considered. The experimental data was collected by way of the Taguchi experimental design and the data were analyzed statistically, the ANOVA was shown the effect of the process parameters. The confirmation experiments showed the optimal operational condition of surface roughness and material removal quantity. The collected data were analyzed using statistical software in order to establish a nonlinear regression model of abrasive magnetic process parameter and quality characteristic. The optimal parameter condition in processing the stainless SUS304 material was conducted using two stage processes; the first stage was rough cutting in the material and then finished cutting the material. Prior to the rough cutting, the Rmax value is equal to 2.572 um, after the rough cutting the Rmax value is equal to 0.153 um. The finished cutting can even obtain a more precious Rmax value being equal to 0.100 um which is like mirror surface. It can be proved that magnetic abrasive finishing is one of the highest efficiency and precision technologies.

Magnetic abrasive finishing is process of abrasive machining conditions, by using magnetic field energy and abrasives on different such as spindle speed, feed rate, abrasive size and the gap between tool and workpiece etc. Magnetic abrasive finishing can effectively remove burrs and increase surface finish, especially suited for the inner hole and groove. Magnetic abrasive finishing not only provides workpiece with high machining accuracy and minimal surface damage, but also has the advantages of mass production and speed. This paper integrates machine center cutting process and magnetic abrasive finishing (MAF) producing a combined process that improves the magnetic abrasive loss rate (MALR) and surface roughness (SR) of aluminum alloy 6061-T6 with ladder shape of different height. The present study shows the features of the development with mathematical model based on response surface methodology (RSM) for correlating the interactive and second order influences of major machining parameters such as different size and shape abrasive of stainless, spindle speed, tool and workpiece gap, feed speed, respectively. The experiments design, regression analysis and analysis of variance are used to develop the relationships between process parameters (abrasive size, spindle speed, tool and workpiece gap, feed speed) and responses (MALR and SR) in MAF process. Sensitivity analysis has also been carried out using developed empirical equations. The results shows that developed mathematical models can be applied to estimate the effectiveness of process parameters for MALR and SR with a change of spindle speed affects the MALR more strongly than SR relatively compare to other parameters.

Resumen

Abstract. The authors describe the method of calculating the magnetic forces in the working gap in the case of magnetically abrasive machining of flat surfaces of billets from magnetic materials by the periphery of a circular inductor on permanent magnets. The application of the software package ANSIS Maxwell for the calculation of the magnetic induction method in the working gap and the magnetic forces of the magnetically abrasive powder acting on the grain is shown. As a result of the work, the magnetic induction in the working gap was calculated for magnetically abrasive machining of flat surfaces of billets from magnetic materials by an inducer on permanent magnets. Also, calculations showed the distribution of the magnetic abrasive powder in the working gap, depending on the material of the workpiece being processed. In the case of magnetically abrasive machining of a magnetic workpiece, the powder in the working gap is concentrated in the zones with the greatest density of force lines - under the inductor poles. An analysis is made of the distribution of magnetic forces in the working gap during magnetic abrasive machining.

Resumen

Abstract Nickel-based superalloys have a wide range of high-temperature applications, such as turbine blades. The complex geometries of these applications and the specific properties of the materials raise difficulties in the surface finishing. Magnetic abrasive finishing (MAF) has proven effective in finishing the complex geometries. In MAF, the magnetic properties of the workpiece, tool, and abrasive play important roles in controlling finishing characteristics. This paper presents the effects of nickel coating on the abrasive behavior during finishing and resulting finishing characteristics of Ni-based superalloys. The Ni-coated diamond abrasive is more attracted to the magnet than the Ni-based superalloy surface. As a result, fewer Ni-coated diamond abrasive particles, which are stuck between the magnetic-particle brush and the target surface, participate in surface finishing. Because of this, coupled with the reduced sharpness of abrasive cutting edges due to the coating, Ni-coated diamond abrasive cannot effectively smooth the target surface in MAF. However, the Ni coating is worn off during finishing of the hard, rough, additively manufactured surface. Then, the diamond abrasive participates in finishing as uncoated diamond abrasive and facilitates the material removal, finishing the target surface.

Resumen

Magnetic Abrasive Finishing (MAF) is one of the nontraditional machining methods with vast applications in high-tech industries such as medical, aerospace and semiconductor manufacturing areas. Several researches have been done in order to studying the influence of various parameters on magnetic abrasive finishing process and characteristics of finished surface. The present paper investigates the effects of some effective parameters such as mesh size of the abrasives, the weight of the abrasive powder and the number of cycles on internal surface roughness of Aluminum tube. The optimum percentage of oil should be added to the abrasive powder was attained and applied for the main tests. Then, design of experiments (DOE) methods and Analysis of Variance (ANOVA) have been applied to determine significant factors and also to obtain an equation based on data regression.

Resumen

Magnetic abrasive used for the internal finishing of capillary tubes, which prevents accumulation of contamination and erratic flow of the conveyed fluid, is a composite particle, consisting of iron and Al2O3 abrasive grains. The irregularity of the magnetic abrasive shape, due to the mechanical crushing process, causes non-uniform depth of cut of the abrasive and restricts the improvement of the finished surface quality. This has resulted in a narrow range of finishing performance. Moreover, the irregularity of the magnetic abrasive shape brings about difficulty in merely introducing it into capillary tubes. To break through these difficulties, this research proposes to develop a spherical iron-based magnetic abrasive, which carries Al2O3 grains on the surface, made by plasma spray. This paper firstly examines the feasibility of the plasma spray to make the existing magnetic abrasive more spherical, and suggests the conditions needed to produce the spherical magnetic abrasive. Secondly, it studies the development of the new spherical magnetic abrasive made of separate particles: iron particles and Al2O3 abrasive grains, which carries the nonferrous abrasive on the outer surface alone. Their finishing performance, evaluated through the experiments using SUS304 stainless steel tubes, shows their applicability to magnetic abrasive finishing.

Resumen

With advancement of technology, finely finished surface is one of the major requirements of modern industry. Fine machining with conventional edged tools is uneconomical and sometimes impossible. Magnetic Abrasive Finishing (MAF) is one promising process which is able to remove the material at micro/nano from metallic and non metallic surfaces. The magnetic abrasives play vital role in MAF. Literature reveals different techniques such as sintering, plasma, chemical, etc. for manufacturing of bonded magnetic abrasives. In the present paper, the bonded magnetic abrasives prepared by a new technique called mechanical alloying have been successfully used for the internal finishing of the brass tubes. After rough boring operation, the inner surface of the tubes is finely finished by newly developed magnetic abrasives. Best surface finish obtained by using these magnetic abrasives is of the order of 9 nm.
