Parametric Optimization of Magnetic Abrasive Finishing Using Adhesive Magnetic Abrasive Particles

Abstract

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.
