Abstract
Based on the analysis of various disfigurements of carbon fiber reinforced plastics
formed in drilling process, the formation model of disfigurement is built up, and analysis results
shows that the main reason of disfigurement is the exceeding cutting force. By focusing on these
problems, new-type drill—super-hard electroplated abrasive drill is developed, and some
experiments were carried out. Compared with the traditional sintered-carbide drill in drilling, the
super-hard electroplated abrasive drill has lower drilling force, better drilling quality, higher
machining efficiency, and longer life-span. A conclusion that super-hard electroplated drill is more
suitable for drilling CFRP is gained.
