The method enables precise detection of the material interface, ensuring optimal process conditions for each material without requiring additional sensors. Key quality metrics - burr height and delamination factor - were analysed under various switching conditions. Results reveal that switching parameters when the cutting edge fully engages the aluminium layer minimizes interface defects and enhances hole quality. The strategy proves superior to compromise parameter sets, reducing delamination in CFRP and burr formation in AA7075-T6, while maintaining productivity. This adaptive approach demonstrates high reliability and industrial applicability, offering significant improvements in hybrid material drilling for aerospace manufacturing.entrueDrilling DefectsOne-Up DrillingPower-Based Process Controlconference paper
