Experimental Investigation and Its Parametric Analysis of AWJM Process Parameters on Surface Quality of Green Composites

The present work aims to investigate the effects of the abrasive water jet machining (AWJM) process on the surface quality of green composites (GC) through an experimental investigation and parametric analysis. Experiments are conducted-based Taguchi (L27) OA by varying AMGS, SoD, NS, AMFR & WP, and the corresponding responses like surface quality (Ra) are measured. Thereafter, effect of process parameters and most optimal combinations for AWJM process is identified through parametric and ANOVA. Furthermore, utilizing liner regression analysis, a mathematical model is created for the best Ra prediction for the AWJM procedure. In order to validate with the experimental findings, the confirmatory analysis has finally been tested. According to the results, Ra is significantly influenced by the parameters, namely AMGS, AMFR, SoD, and NS. The ideal setting for AWJM process is obtained as AMFR as 2 g/s, WP as 80MPa, SoD as 2.5 mm, NS as 200 mm/min, and AMGS as 40 mesh.
