Influence of AWJM parameters on surface quality of BSHC

Natural fiber hybrid composites are replacing synthetic fiber composites, which improves environmental cleanliness. In this investigation, a compression molding process was used to produce a Banana/Sisal Hybrid Composite (BSHC) and the influence of Abrasive Water Jet Machining (AWJM) process parameters on surface quality was studied. The AWJM experiments were conducted using the design of experiment techniques, with parameters such as water pressure (P), nozzle transfer speed (d), and standoff distance (s). During the AWJM process, P was identified as the most significant parameter influencing surface quality. The optimum machining parameters (P-3, d(1), s(1)) provide better surface quality which produces a surface roughness of 10.1 mu m. The experimental surface roughness values have a better correlation with the predicted surface roughness which shows the efficiency of the prediction model.
