| dc.description.abstract | Currently, there is a notable attraction within the industry towards biocomposites, driven by the increasing fascination with natural fber-reinforced composites (NFRCs). These NFRCs ofer remarkable benefts, including cost-efectiveness, biodegradability, eco-friendliness, and favorable mechanical properties. As a result, the manufacturing processes of natural fber reinforced polymer (NFRP) composites have garnered attention from both industrial professionals and scientists. The emergence of these eco-friendly materials in the automotive and aerospace industries has sparked interest in understanding their production techniques. However, the machining processes of NFRP composites pose signifcant challenges due to the complex structure of natural fbers, necessitating thorough studies to address these issues efectively. This research paper presents a comprehensive investigation on surface roughness during the milling process of Alfa/epoxy biocomposites. A set of 100 experimental trials was conducted to test the surface roughness, and analysis of variance (ANOVA) was used to assess the impact of cutting parameters and chemical treatment on surface quality. To develop a predictive model for surface roughness, a hybrid approach called ANN-GA (artifcial neural networks-genetic algorithms) is proposed in this research. This approach combines ANN and GA to determine an optimal neural network archi tecture. The performance of the ANN-GA model is compared to the Levenberg–Marquardt backpropagation (LM) algorithm. ANOVA results show that the feed per revolution have a signifcant infuence on surface roughness, followed by the chemi cal treatment of fbers, while machining direction has a smaller efect. The ANN-GA model demonstrates good accuracy in surface roughness prediction compared to the LM algorithm | en_US |
