Natural fiber-reinforced composites have garnered increasing interest in the manufacturing and engineering sectors due to their favorable properties such as low density, biodegradability, cost-effectiveness, and excellent strength-to-weight ratio. With the global shift towards sustainability, industries are turning to eco-friendly materials that offer a combination of high performance and minimal environmental impact. This study delves into the optimization of CNC milling process parameters for natural composites fabricated using banana, aloe vera, and hemp fibers, with the aim of enhancing machinability while maintaining mechanical integrity. Following the ANOVA, a backward elimination method is used to further refine the optimization process. This involves systematically removing the insignificant parameters—those that do not contribute meaningfully to the machining performance. The elimination is done carefully to ensure that the exclusion of a parameter does not compromise the model´s predictive power or the quality of the machining process. The backward elimination method streamlines the experimental model by focusing only on the critical input parameters.
