  "abstract": "In the present research, drilling operations were performed on h-BNNS-reinforced Al-6082 nanocomposites to investigate the influence of key drilling parameters rotational speed (RS), feed rate (f), and reinforcement content of h-BNNS (Rein) on hole quality characteristics, including circularity error (CE), cylindricity (Cy), and conicity (Ct). The nanocomposites were fabricated using the stir casting method, and a total of 20 experiments were designed and executed using a Rotatable Central Composite Design (CCD). A full quadratic model was developed, and Analysis of Variance (ANOVA) was employed to evaluate model adequacy. The results showed that CE initially decreased with increasing RS and feed rate up to mid-levels, followed by an increase, with feed having a more pronounced effect. Cylindricity increased with all parameters up to a point, then decreased to a minimum. The three hole quality parameters were simultaneously optimized using NSGA-II and TLBO algorithms for realizing pareto optimal solutions. Both algorithms showed considerable efficiency in predicting optimal drilling conditions for improved hole characteristics such as RS = 0.205, Feed = − 0.922, and Rein = 1.630, yielding CE = 0.1435, Ct = − 0.0070, and Cy = 0.9245. The percentage deviations between experimental and predicted values were found to be 9.45%, 22.22%, and 7.94% for NSGA-II, and 4.08%, 15.09%, and 5.07% for TLBO in terms of CE, Cy, and Ct, respectively.",
