| 摘 要： | 为了提高C/E复合材料构件制孔加工质量,以C/E复合材料为研究对象,提出"以磨代钻"制孔新工艺,并研制了电镀金刚石刀具.与传统硬质合金刀具钻孔工艺进行对比试验,结果表明:金刚石刀具钻削轴向力降低30%-50%、刀具耐用度提高3-5倍、缺陷显著减少,更适合C/E复合材料钻孔加工.

| Abstract: | Carbon fiber reinforced plastics is one of typical difficult to machine materials which will easily bring on disfigurements such as burrs, delamination and avulsion during drilling. In order to improve the drilling quality,the carbon fiber/ epoxy(C/E) composite was studied, and a grinding drill and its new process were developed. Some experiments on the grinding tool were carried out. The results show that the thrust force decreases by 30% -50%, the tool life is improved by 3 to 5 times and the disfigurements are minimized compared with the traditional carbide twist drill.
