This study evaluates the performance of magnetic abrasive finishing (MAF) of aluminum alloy in terms of achieving materials removal (MR). A vertical milling machine is used to perform the finishing process using a developed MAF unit that consists of an inductor made out of a 150 mm long and 20 mm diameter iron core wound with 1500 turns and 0.5 mm copper wire. The commutator and magnetic pole are attached at the top and bottom of the inductor, respectively. The required current is supplied using a DC power supply. The South Pole workpiece is a 100×50×3 mm3 plate of AA 1100 aluminum alloy, whereas the magnetic pole represented the North Pole. Pole rotational speed, applied current, and abrasive finishing time was selected as input parameters of the MAF with three-level of (270, 600. 930 rpm; 0.5, 1, 1.5 Amp; 6,9,12 min). The L9 orthogonal array of the Taguchi method was utilized to examine the impact of each independent input. The obtained results clarify that applied current was the most effective factor in terms of its contribution (63.16%) in the produced MR, followed by time finishing and rotational speed.

Magnetorheological finishing (MRF) is used to precisely finish various materials such as hard crystals, optical, and brittle materials. In this paper, the thermal behavior of the MRF process is studied theoretically and experimentally on thin copper substrate surface by varying rotational speed and working gap. The wall shear stress (WSS) represents the frictional force per unit area exerted by the flowing magnetorheological (MR) fluid on the workpiece surface and it is determined using three-dimensional computational fluid dynamics numerical simulations that use a dynamic viscosity model based on the variable magnetic flux density. A thermal model is proposed to predict heat generation and temperature rise on the workpiece surface with the help of energy partitioning, heat conduction equations, and WSS. It is observed that the temperature rises with increasing the rotational speed and reducing the working gap. Considering MR fluid with only abrasive particles, the theoretical temperature rise of 21.32 °C was predicted. When MR fluid is with carbonyl iron particles and abrasive particles, the theoretical temperature rise was 19.37 °C. In experiments, the maximum temperature rise of 14.8 °C was obtained. Finite element analysis is performed to estimate magnetic flux density variation on the workpiece surface and viscosity variation over the workpiece surface. Surface roughness (Sa) reduced from an initial value of 0.236 µm to 0.079 µm at 600 rpm tool rotational speed and 3 mm working gap.
