Abstract
The wear-resistant metal bonded diamond drill was applied to the drilling of carbon fiber epoxy composites in order to increase the drilling performance without fuzzing and delamination. For the first time, the helical-feed drilling method was applied to overcome the drilling depth limitation in the conventional drilling with metal bonded diamond drill. From the drilling experiments, it was found that the helical-feed method employed in this work was efficient and did not cause thermal damage in high speed drilling.Keywords
