On surface integrity of Al 2014 alloy finished by Ultrasonic Assisted Abrasive Flow Machining

Abstract

Ultrasonic Assisted Abrasive Flow Machining (UAAFM) is a finishing process for both external and internal surfaces such as holes that are not necessarily straight and of long length. The latter type prohibits the use of a simple honing tool. In UAAFM hard abrasive particles are mixed in a carrier fluid and flown past. The hole surfaces at fairly high speeds back and forth using hydraulic circuits. It has been observed that providing ultrasonic harmonic motions to the work-piece or the fluid or both can improve the material removal rate and surface finish. The present paper discusses an experimental study on finishing internal primitives of Al alloy 2014 series with effect of ultrasonic assistance work-piece on process performance in axial vibrations.
