Investigation of Magnetic Abrasive Finishing for Internal Polishing of Aluminium Tubes Using DOE
Magnetic Abrasive Finishing (MAF) is one of the nontraditional machining methods with vast applications in high-tech industries such as medical, aerospace and semiconductor manufacturing areas. Several researches have been done in order to studying the influence of various parameters on magnetic abrasive finishing process and characteristics of finished surface. The present paper investigates the effects of some effective parameters such as mesh size of the abrasives, the weight of the abrasive powder and the number of cycles on internal surface roughness of Aluminum tube. The optimum percentage of oil should be added to the abrasive powder was attained and applied for the main tests. Then, design of experiments (DOE) methods and Analysis of Variance (ANOVA) have been applied to determine significant factors and also to obtain an equation based on data regression.
