A Comprehensive Experimental Study on Finishing Aluminum Tube by Proposed UAMAF Process

Abstract

In this paper, a new noncontact ultrasonic magnetic abrasive finishing mechanism is presented. An ultrasonic vibration producer is used to vibrate the permanent magnets. The ferromagnetic steel grits in the created magnetic field form a flexible finishing tool. To take advantage of cavitation collapse pressure, the finishing zone components are immersed in water. The present work also studies the effect of parameters, i.e., time duration for finishing and working gap between magnetic poles and the workpiece on the surface roughness (Ra). The microscopic pictures and the roughness profile diagrams demonstrate the advantages of the proposed method.

Notes

*Surface Roughness Variation = (Ra before finishing — Ra after finishing)/Ra before finishing.

**(–) sign presents reduction of surface finish.
