abstract

This paper aims to investigate the effectiveness of super-hard ceramic coatings by evaluating tool wear when drilling carbon fiber reinforced plastics (CFRP) composite. The drilling experiments of CFRP are conducted with diamond-like coating (DLC) coated, AlMgB14 (BAM) coated, AlCrSiN coated, and uncoated tungsten carbide drills. Tool wear evolution is measured qualitatively as well as quantitatively using the scanning electron and confocal laser scanning microscopes. Both DLC and BAM coatings failed when drilling CFRP only within 10 holes while AlCrSiN coating did not fail. Failure mechanisms of each coating when drilling CFRP are discussed.
