탄소섬유강화 플라스틱의 고정도, 고능률 드릴링 가공

Highly Precise and Efficient Drilling of Carbon Fiber Reinforced Plastics

The high strength and wear-resistant metal bonded diamond wheel was applied to the drilling process of carbon fiber reinforced plastics (CFRP), The helical-feed drilling method was use for the first time to overcome the limit of drilling depth of the conventional drilling process and to improve the dressing of the wheel. The helical-feed drilling method was found effective at high cutting speed without the limit of drilling depth.
