Reported drilling methods for CFRP/Ti stacks include twist drilling, end milling, core grinding, and their derived methods. The literature does not have any report on drilling of CFRP/Ti stacks using rotary ultrasonic machining (RUM). This paper, for the first time, reports a study on drilling of CFRP/Ti stacks using RUM. It also compares results on drilling of CFRP/Ti stacks using RUM with reported results on drilling of CFRP/Ti stacks using other methods. When drilling CFRP/Ti stacks using RUM, cutting force, torque, and CFRP surface roughness were lower, hole size variation was smaller, CFRP groove depth was smaller, tool life was longer, and there was no obvious Ti exit burr and CFRP entrance delamination. Ti surface roughness when drilling of CFRP/Ti stacks using RUM was about the same as those when using other methods.
报道的 CFRP/Ti 叠层钻削方法包括扭转钻削、端铣、芯磨及其衍生方法。文献中没有关于使用旋转超声加工(RUM)钻削 CFRP/Ti 叠层的报道。本文首次报道了使用 RUM 钻削 CFRP/Ti 叠层的研究。还将使用 RUM 钻削 CFRP/Ti 叠层的结果与使用其他方法钻削 CFRP/Ti 叠层的报道结果进行了比较。使用 RUM 钻削 CFRP/Ti 叠层时,切削力、扭矩和 CFRP 表面粗糙度较低,孔径变化较小,CFRP 槽深较小,刀具寿命较长,且无明显的 Ti 出口毛刺和 CFRP 入口分层。使用 RUM 钻削 CFRP/Ti 叠层时的 Ti 表面粗糙度与使用其他方法时大致相同。
