Epoxy nanocomposites play a leading role in manufacturing sectors due to excellent engineering properties. This paper highlights the influence of process constraints and the development of a robust optimization approach during drilling of Multiwall carbon nanotube/Epoxy Nanocomposites. The parameters considered are MWCNT % (W), Drill bit speed (N), feed rate (F), and Drill Bit (M) Materials (HSS, Carbide, TiAlN) based on pilot experiments performed and existing literature. The unified aim is to achieve the best machining performances, i.e., Surface roughness, Torque, and Thrust force. The optimal setting was found as W-1.0%, N-1000 rpm, F-50 mm/min with TiAlN drill bit. A comparative study between GRA and GRA-PCA hybrid modules has been performed to check the application potential, which shows that Hybrid GRA-PCA is more capable than traditional GRA in terms of less average error (5.037%) and overall improvement of 13.99% in assessment values.

环氧纳米复合材料由于出色的工程性能而在制造领域起着领导作用。本文着重介绍了在多壁碳纳米管/环氧树脂纳米复合材料钻孔过程中工艺约束的影响以及稳健优化方法的发展。根据执行的试验实验和现有文献，考虑的参数为MWCNT％（W），钻头速度（N），进给速率（F）和钻头（M）材料（HSS，硬质合金，TiAlN）。统一的目标是获得最佳的加工性能，即表面粗糙度，扭矩和推力。使用TiAlN钻头发现最佳设置为W-1.0％，N-1000 rpm，F-50 mm / min。进行了GRA和GRA-PCA混合模块之间的比较研究，以检查其应用潜力，
