Why is it important?
It’s important because it develops an effective way to drill advanced hybrid aluminium composites used in aerospace, automotive, and electronics, where high strength, low weight, and precise machining are critical. By using the hybrid GRA-PCA-TOPSIS technique, this work finds the best process settings to maximise drilling speed and minimise errors, defects, and tool wear, which saves time, reduces costs, improves product quality, and makes the machining of new composite materials more efficient and sustainable.
Perspectives
This research highlights the potential of hybrid GRA-PCA-TOPSIS optimization for advanced machining of sustainable hybrid composites. The approach can guide future work on precision drilling of lightweight materials, promoting efficiency and eco-friendly reinforcement strategies for aerospace and automotive applications.
