Abstract

Recent needs to superfinished surfaces have motivated researchers to study on modern methods of polishing. Magnetic-assisted finishing is one of those methods which can generate mirror-like finished surfaces. This paper investigates the effects of some parameters, i.e., rotational speed of the permanent magnetic pole, working gap between the permanent pole and the workpiece, number of cycles, and the weight of the abrasive particles on aluminum surface finishing. Three-level full factorial method was used as design of experiments technique to study the selected factors. A total of 54 designed tests were done on aluminum sheet using an innovative material removal mechanism. Analysis of variance was used to determine significant factors and also to obtain an equation based on data regression. Experimental results indicate that the number of cycles and working gap are the most significant parameters on surface roughness change (∆Ra), followed by rotational speed and then weight of powder.
