摘　　要：针对CFRP/Ti叠层材料在一体化制孔过程中轴向力过大而引起的分层损伤和出口毛刺等制孔问题,从降低叠层制孔轴向力的角度出发,采用螺旋铣孔的方式,结合超声辅助加工技术应用于CFRP/Ti叠层材料叠层制孔。设计系列加工试验,对比研究了有无超声辅助条件下叠层材料螺旋铣孔的轴向力,以及主轴转速、螺距、切向每齿进给量、偏心距和振幅对轴向力的影响规律,并初步得到工艺参数优化结论。结果表明,在超声辅助条件下CFRP/Ti叠层材料螺旋铣孔的轴向力明显减小。其他工艺参数对轴向力的影响程度大小顺序为偏心距>螺距>切向每齿进给量>振幅>主轴转速。The spiral milling hole method was used to reduce the axial force of laminated hole-making,and integrated ultrasonic-assisted machining technology was applied to the hole-making of CFRP/Ti laminated material to address the hole-making issues,such as delamination damage and exit burr,caused by excessive axial force in the hole-making process of CFRP/Ti laminated material.The axial force of laminated material spiral milling with and without ultrasonic assistance was compared and studied through a series of machining experiments.The impact of spindle speed,pitch,tangential feed per tooth,eccentric distance,and amplitude on the axial force was also examined,and a preliminary conclusion regarding process parameter optimization was reached.The results show that the axial force of CFRP/Ti spiral milling process is greatly reduced by using ultrasonic assistance.The following process variables have an impact on this force in the order of significance:eccentric distance>pitch>tangential feed per tooth>amplitude>spindle speed.
