摘要： 针对紫铜薄壁微铣削加工过程中的位移变形问题,建立了铣削力数学模型,采用四边形薄板单元有限元方法对薄壁铣削的位移变形进行分析预测。为了验证铣削力模型和薄壁变形预测的准确性,利用金刚石微铣刀对紫铜进行铣削试验。最后,通过光学显微镜和扫描电镜进行观测。结果表明:本文试验结果与仿真结果几乎吻合,证明本文建立的铣削力模型及采用的薄板变形分析方式可以有效地预测加工变形,且载荷位置与薄壁变形关系密切,切削变形随薄壁厚度的减小而快速增大。

Abstract: According to the deformation of copper thin-wall part in micro milling, a mathematical model of the milling force was established. The method of quadrilateral thin plate element FEM was used to predict the deformation caused by the cutting force. Experiments with diamond coated cutters were carried out to the validate the feasibility of the model and the precision of the deformation prediction. Optical Microscope (OM) and Scanning Electron Microscope (SEM) were used to observe the milled surface. Results show that the proposed mathematical model and analysis method can effectively predict the milling deformation of copper thin-wall parts. There is a close relationship between the load position and the thin-wall deformation. The cutting deformation increases quickly with the decrease in the thickness of the thin wall.

Key words: machanical design, cutting deformation, finite element method(FEM), thin-wall, micro milling
