摘要
传统钻削工艺对碳纤维复合材料制孔时容易产生毛刺、撕裂和分层等加工缺陷。然而,作为一种新型制孔工艺,螺旋铣削在航空难加工材料中的运用越来越广泛。为了分析不同工艺对碳纤维复合材料制孔的影响,在相同切削速度和进给速度的条件下,分别对碳纤维复合材料传统钻孔和螺旋铣孔进行试验,并对制孔过程中的轴向力和加工质量进行检测和分析。结果表明：当切削条件相同时,螺旋铣孔下的轴向力仅仅是传统钻孔的33.97%~51.23%;而且,螺旋铣孔的加工质量要优于传统钻孔,从而更适用于碳纤维复合材料加工。
Many defects such as burrs, tears and delamination are often observed in conventional drilling carbon fiber composite. While, as a novel hole-making process, helical milling is used for machining avia-tion difficult materials more and more widely. In order to analyze effect of different hole-making processes on carbon fiber composite material, under the same conditions of cutting speed and feed rate, comparative tests are carried out, then the thrust force and machining quality are detected analyzed. The results show that：when the cutting conditions are the same, the thrust force of the helical milling is only 33. 97% ~ 51. 23% of conventional drilling;besides, machining quality of helical milling is superior to the traditional drill-ing, thus helical milling is more suitable for carbon fiber composite material processing.
