摘要
本文基于单颗磨粒的运动轨迹方程,采用ABAQUS有限元软件模拟了螺旋铣磨过程,并对孔出入口边缘的应力分布情况和铣磨力的变化规律进行仿真分析。研究了在螺旋铣磨制孔过程中,碳纤维复合材料(CFRP)铣磨力的变化规律和不同工艺参数对铣磨力的影响程度,随后设计螺旋铣磨正交试验,采用极差分析法分析试验结果,并与仿真结果进行对比验证以确定仿真的准确性。研究结果表明:主轴转速与轴向铣磨力呈负相关,并且F_(x)在3 500 r/min时最小,公转转速、螺距与铣磨力呈正相关;公转转速对切向铣磨力的影响程度最大,主轴转速和螺距次之;公转转速对轴向铣磨力的影响程度最大,螺距和主轴转速次之。
Based on the motion trajectory equation of a single abrasive grain,this paper uses ABAQUS finite element software to simulate the helical milling process,and analyzes the simulation of the stress distribution at the edge of the hole inlet and outlet and the variation law of milling force.During the process of spiral milling holes in carbon fiber reinforced plastic(CFRP),the variation law of milling force and the influential degree of different process parameters on milling force are studied.Subsequently,an orthogonal experiment for spiral milling was designed,using range analysis to study the experimental results and comparing them with the simulation results to determine the accuracy of the simulation results.The results show that the spindle speed is negatively correlated with the axial milling force,and F_(x) is minimal at 3500 r/min.The rotational speed and pitch are positively correlated with the milling force.The revolution speed is the main factor affecting the tangential milling force,while the spindle speed and pitch are the secondary factors.The revolution speed is the main factor affecting the axial milling force,while the pitch and spindle speed are the secondary factors.
