AB  - The effect of Magnetic Abrasive Finishing (MAF) method on the Temperature rise (Tr) and the
surface Roughness (Ra) has been investigated in this research by determining the optimum temperature through
the optimum surface roughness to improve the quality of surface layer for CuZn28 brass alloy plates. Sixteen
runs were done in order to determine the optimum temperature in the contact area (between the abrasive powder
and surface of workpiece) and the change in the surface Roughness ()Ra) according to Taguchi Orthogonal
Array (OA). Four technological parameters (cutting speed, finishing time, working gap and the current in the
inductor) with four levels for each parameter have been used, the matrix known as a L16 (4<sup>4</sup>) OA. The Signal to
Noise (S/N) ratio and Analysis of Variance (ANOVA) techniques were performed for analysing results of Tr
and )Ra using the statistical software (MINITAB17), to establish the best optimum condition and identify the
significant parameters affecting on the temperature rise and surface roughness. The modern and powerful
technique IR camera was used to measure the temperature while scanning electron microscopy was utilized to
study the texture of finishing surface. The results showed that the optimum temperature in contact area of
workpiece is (55.1&deg;C) and the most significant factor for CuZn28 brass effect on )Ra for MAF process was the
cutting speed followed by current in the inductor, finishing time and working gap.
