Optimization of Abrasive Water Jet Machining Parameters for Improved Surface Quality and Material Removal Rate in Stacking Composite

Abstract

This research presents the machinability of a hybrid steel mesh/basalt fiber/jute fiber stacked composite under abrasive water jet machining (AWJM), an experimental analysis based on the design of experiments is carried out in this work. Hybrid steel mesh/basalt fiber/jute fiber stacked composites were fabricated using a vacuum-assisted resin transfer molding (VARTM) process. The objective of this study is to investigate a relationship between abrasive pressure, traverse rate, abrasive amount rate, and nozzle distance in order to evaluate the surface roughness, kerf angle, and material removal rate of a Stacking composite (SC) made of Steel mesh, basalt fiber, and jute fiber (WBJBJW). The impact of each parameter on the result was evaluated using the Analysis of Variance (ANOVA) approach. To obtain a reduced surface roughness, kerf angle, and a better material removal rate, the process parameters were optimized using the desirability optimization technique. The experimental interpretations were carried out using the L29 Central Composite Design (CCD). The statistical method was used to assess the impact of each unique AWJC element. It was revealed that the aqua jet pressure had the greatest impact on the rate of material removal and surface roughness. The SR and KA, which decreased by 10.81% and 50.36% as the AJP strengthened at 300 MPa, were found to be influenced by the AWP. The desirability analysis (DA) optimises the AWJC characteristics of the (WBJBJW). It was discovered that the AWP had an impact on the SR and KA, which reduced by 10.81% and 50.36% when the AJP increased at 300 MPa. Results of SR, KA, and MRR values predicted by the RSM are evaluated using experimental data, showing that they agree with one another with minimal or no error.
