摘　　要：随着国内航空航天业以及汽车轻量化趋势的发展,高质量、高效的碳纤维增强复合材料(Carbon Fiber Reinforced Plastics,CFRP)制孔技术已成为各行业的基本要求。本文采用直径为8mm的YG6X类硬质合金麻花钻,所使用的复合材料板材为采用RTM法自主制备的碳纤维复合材料板材,研究切削参数(主轴转速n=3000,4500,6000,7500r/mm,进给量Vc=10,20,30mm/min)对轴向力和成孔质量的影响规律。结果表明,轴向力随着进给量的增加而增加,随着主轴转速的增加而减小。并且在低进给的条件下,孔入口处均未出现撕裂和毛刺,但在孔出口处出现较为明显的毛刺。With the development of domestic aerospace industry and automobile lightweight trend,the high-quality and efficient hole making technology of carbon fiber reinforced plastics(CFRP)has become the basic requirement of various industries.In this paper,YG6 X type cemented carbide fried dough twist drills with a diameter of 8 mm are used.The composite plates used are carbon fiber composite plates independently prepared by RTM method.The effects of cutting parameters(n=3000,4500,6000,7500 r/mm,Vc=10,20,30 mm/min)on axial force and hole forming quality are studied.The results show that the axial force increases with the increase of feed rate and decreases with the increase of spindle speed.Under the condition of low feed,there are no tears and burrs at the hole inlet,but obvious burrs at the hole outlet.
