Effect of Process Variables in improvement of Surface Roughness during Finishing of Al-6061 Alloy using Abrasive Flow Machining

Abstract

Abrasive flow machining is unconventional machining process which is used to remove material and improve surface roughness. Abrasive flow machining (AFM) is very efficient and suitable for finishing of complex inner surface and difficult to reach surface. In the present study the effect of different input parameters in improving surface roughness has been investigated by using Taguchi method. An experimental study was carried out on Aluminium-6061 work piece. The abrasive size, properties of carrier, no of cycles and abrasive concentration are important parameters that affect the performance of AFM. The objective is to study the effect of process variables in improving surface roughness.
