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.
