摘要
利用DEFORM-3D三维有限元软件模拟高速铣削过程,分析铣削力与切削厚度间的线性关系,建立瞬时铣削力-瞬时切削厚度数学模型。通过一维搜索分离出刀具偏心跳动引起的铣削力并予以再次有限元模拟,完成刀具偏心跳动参数辨识,最终通过平头立铣刀加工AL6061-T6试验验证有限元模拟预测刀偏铣削力模型的正确性,为铣削力学分析与参数优化提供参考。
DEFORM-3D is used to simulate the high-speed milling process. The linear relationship between milling force and cutting thickness is analyzed. The mathematical model of instantaneous milling force instantaneous cutting thickness is established. Through one-dimensional search, the milling force caused by tool eccentric runout is separated, and the finite element simulation is carried out again, and the parameter identification of tool eccentric runout is completed.Finally, the correctness of the model is verified by the experiment of AL6061-T6 machining with flat end milling cutter,which provides a reference for milling mechanics analysis and parameter optimization.
