Investigation of process parameters by abrasive assisted electrochemical micro drilling process on Al - 6061with SiC and Fly ash composites

Abstract

This attempt investigates on upgrading the required parameters of micro hole machining process like frequency, voltage, electrolyte concentration of abrasive assisted Electrochemical machining process. This work focuses on optimizing the methodology of abrasive assisted ECM process parameters and comparing it with straight ECM process. The experimentation is done on AL6061 with hybrid reinforced SiC and Fly ash particles at constant percentage weight. Upgrading process parameter is a statistical technique, where the independent input process parameters such as frequency, voltage, electrolyte concentration were imported to initiate the AECM process. The process performance is measured in terms of material removal rate (MRR) and precision of micro hole dimension (OC) and the results obtained were compared for both process(abrasive and without abrasive ECM for AL6061-10 wt% of SiC -10 wt% of Fly ash). The hybrid composites of Al6061 containing 10 wt% of (SiC& Fly ash) particles were prepared by using liquid metallurgy route. The microstructure, wear and mechanical properties of the fabricated AMCs were analyzed.
