Abstract Magnetic abrasive finishing (MAF), an unconventional process, enhances the surface finish of a material. The current research focuses on its use with SS310s. The finite element analysis (FEA) result shows the effect of control parameters on the magnetic flux density. In FEA analysis, it was decided to maintain an air gap of 1.5-2 mm and a voltage of 10-20 V. A response surface methodology (RSM) desirability function is used to identify the optimal process parameters. Experiments are conducted for optimizing the process parameters like voltage, rotational speed, machining gap, mixing ratio, and mesh number to enhance the material removal rate (MRR) and surface roughness (Ra). A series of 62 experiments are conducted using optimized process parameters at different levels. Moreover, analysis of variance (ANOVA) is used to identify the percentage contribution of each process parameter in %ΔRa and MRR. From this, the mesh number of the abrasives plays an important role in the finishing process owing to the increased number of cutting edges and because of the uniform normal force (Fn) distribution. The optical microscopic image result and the wear test confirms that the surface finish of SS310s has been improved using MAF.

Abrasive Finishing

In this article, we present a numerical model of a magnetic abrasive finishing station, which was analyzed using the finite element method (FEM). The obtained results were compared with the real values measured on an experimental station of our own design. The prepared station had the option of adjusting the magnetic flux density inside the machining gap, the width of which could be changed from 10 to 30 mm. The maximum value of the magnetic flux density inside the air gap was 0.8 T. The real distribution of magnetic flux density in the finishing area was also analyzed. A design of experiment was carried out with the following variables: abrasive grain concentration, width of the machining gap, and process duration. The results are presented in the form of regression equations and characteristics for selected roughness parameters.

A very precise surface finish is desirable in manufacturing semiconductors, medical equipment, and aerospace parts. The examinations on magnetic abrasive finishing (MAF) processes are being done for the modern industry. This newly developed process is serving the industry to achieve the desired level of precision and surface finish. This research represents the MAF of aluminum pipes using adhesive magnetic abrasive particles. The different process parameters were optimized using the Response Surface Methodology (RSM) method to gain an in-depth analysis of surface roughness in terms of roughness improvement rate (RIR), and material removal rate (MRR). The achieved maximum RIR and MRR was 81.49% and 2.74mg/min, respectively. The finished workpieces were microscopically investigated by scanning electron microscopy (SEM) to further study the mechanism of MAF process.

The Magnetic Field

The traditional magnetic abrasive finishing (MAF) process, the magnetic flux density at the bottom of the magnetic pole is unevenly distributed, resulting in poor uniformity of the finished surface. Therefore, it is proposed to improve the surface quality by attaching a magnetic plate at the bottom of the workpiece to improve the magnetic field distribution. It is confirmed by simulation that the magnetic field distribution at the bottom of the magnetic pole is effectively improved after the magnetic plate is attached. It is proved through experiments that the magnetic plate-assisted MAF process can obtain a smoother surface. The experimental results show that the surface roughness of the glass lens improves from 246 nm Ra to 3 nm Ra through the magnetic plate-assisted MAF process within 45min.

This article evaluates the finishing performance of ultrasonic-assisted double-disk magnetic abrasive finishing process on two paramagnetic materials (copper alloy and stainless steel) with different mechanical properties such as flow stress, hardness, shear modulus, and so on. The finishing experiments were performed based on response surface methodology. The results obtained after finishing have been analyzed to determine the effect of different process parameters such as working gap, rotational speed, and pulse-on time of ultrasonic vibration for both work materials and to study various interaction effects that may significantly affect the finishing performance by the process. The outcome of analysis for the two different work materials has been critically compared to understand the effect of the considered process parameters on the finishing performance of the process based on mechanical properties of the workpiece such as hardness. Furthermore, the scanning electron microscopy and atomic force microscopy were carried on the workpiece surface to understand the possible mechanism of material removal and the surface morphology produced after the finishing process.

This paper proposed a viewpoint to explain why vibration assistance may increase material removal rate (MRR) in vibration-assisted magnetic abrasive finishing process. A series of experiments on vibration-assisted finishing have been carried out. On the basis of these experiments, the finishing characteristics are represented summarily. It was shown that the increase in material rate is mainly due to an increase in material removal per unit working distance.

Lapping is a finishing process used especially for removing the material, achieving finer surfaces, correcting minor imperfections and maintaining close tolerances. This process may takes place due to the relative motion between the work material, slurry and lapping plate. This study is done by conducting a series of experiments based on taguchi design of experiments and calculating material removal rate and surface roughness. This study explains about effect of the parameters on material removal rate and surface finish. The final step of this process is to find out the optimum combination of process parameters to determine the material removal rate and the surface finish.
