Abstract
The effect of the magnetic abrasive finishing (MAF) method on the temperature rise (TR), and material removal rate (MRR) has been investigated in this paper. Sixteen runs were to determine the optimum temperature in the contact area (between the abrasive powder and surface of workpiece) and the MRR according to Taguchi orthogonal array (OA). Four variable technological parameters (cutting speed, finishing time, working gap, and the current in the inductor) with four levels for each parameter were used, the matrix is known as a L16 (44) OA. The signal to noise ratio (S/N) ratio and analysis of the variance (ANOVA) were utilized to analyze the results using (MINITAB17) to find the optimum condition and identify the significant parameters affecting on the TR., and MRR of the steel 304. IR camera was used to measure the experimental temperature. The results showed that the optimum temperature in contact area of workpiece is 70.7 °C.
Highlights
Magnetic Abrasive Finishing (MAF) process is the one in which material is removed in such a way that the surface is finished
The principle work of magnetic abrasive finishing involves filling the working gap between the workpiece and the pole with the magnetic abrasive powder, the current or the magnetic flux density is passed through the coil to produce the magnetic field, and the pole is rotating with the powder along the work piece
The magnetic field provides the abrasive powder with the energy, this energy makes the magnetic abrasive powder as a cutting tool for treating the surface, and the rotation of the pole makes the friction between the workpiece and the magnetic abrasive powder which the material can be removed from the workpiece [3,4]

The magnetic field provides the abrasive powder with the energy, this energy makes the magnetic abrasive powder as a cutting tool for treating the surface, and the rotation of the pole makes the friction between the workpiece and the magnetic abrasive powder which the material can be removed from the workpiece [3,4]. Like number of the turns, and magnetic flux density affect on the materials removal rate [6]. It was concluded that the current, ratio size and the magnetic abrasive powder grain size are more
