| 摘 要： | 以Al-6061铝合金为研究对象,基于Deform有限元分析软件,进行三维切削仿真分析.采用正交试验设计方法,研究车刀双倒棱结构参数对切削力及切削温度的影响规律.仿真试验结果表明,在适当的双倒棱宽度与双倒棱角度下,切削力和切削温度对比单一定值倒棱有明显的减小,研究结果可为倒棱刀具刀尖结构优化和实际切削加工提供理论指导.

| Abstract: | Taking Al-6061 aluminum alloy as the research object,three-dimensional cutting simulation analysis was carried out based on Deform finite element analysis software.The orthogonal experimental design method was used to study the influence of the structural parameters of double chamfers on cutting force and cutting temperature.The simulation results show that the cutting force and cutting temperature are significantly reduced compared with those of chamfering with a single fixed value under the appropriate double chamfering width and angle.The research results can provide theoretical guidance for the optimization of the nose structure of chamfering tools and the actual cutting process. |
