Parametric Optimization of AWJM in AA6351-SiC-B₄C Hybrid Composite Using Grey Relational Analysis

Abstract:

In the present study, the aluminum based hybrid composite with Silicon Carbide (SiC) and Boron Carbide (B₄C) particles are prepared through the stir casting process and subjected to Abrasive Water Jet Machining (AWJM). The pressure, standoff distance and traverse speed are considered as the input process parameters and the output response such as Kerf angle, Material Removal Rate (MRR) and Surface Roughness (Ra) are measured and optimized using Grey Relational Analysis (GRA). The Analysis of Variance (ANOVA) and the F-test are performed to understand the contribution and the significant level of importance of each input parameter over the output response. The experimental result shows that the traverse speed and the standoff distance contributed more on affecting the performance, with a contribution of 62.14% and 18.43% respectively.
