Optimization of Process Parameters of Two Way Abrasive Flow Machining by Grey Relational Analysis Coupled with Principle Component Analysis

Abstract

Now a days as the advancement of technology is increasing rapidly, expectation of human, from industry also increased. To fulfil these expectations new technologies are coming into existence. In this regard unconventional machining processes are playing an important role. Abrasive flow machining is a non-traditional finishing process used for finishing parts with predominantly irregular geometry. In AFM, material removal and surface finish takes place by flowing visco elastic abrasive carrier across the surface to be machined. The media (carrier+abrasive) is the key element in the process because of its ability to precisely abrade the selected area along its flow path. In this study an attempt is made to develop an optimum level of process parameters by using grey relational analysis coupled with principle component analysis. A work piece made of brass having inner diameter 7.7 mm, outer diameter 10 mm and length 17.2 mm is machined in this experimental work. Result shows the effect of various input parameters on material removal rate, surface roughness and find out a set of parametric combination which is optimum.
