摘要
采用单因素试验法,利用ThirdWaveAdvantEdge有限元软件研究麻花钻的钻尖几何参数对钛合金钻削工艺性的影响,运用PowerLaw本构模型建立Ti6Al4V钛合金材料参数。验证麻花钻参数在合理的取值范围内,Carbide-General硬质合金麻花钻不同的后角、螺旋升角、横刃斜角和刃口钝圆半径对钛合金钻削性能的影响。通过钛合金钻削过程的有限元分析,为麻花钻钻削钛合金材料时的钻头几何参数合理选择提供了参考依据。
In this paper,the single factor experiment method is used to study the influence of the geometric parameters of the drill tip on the drilling process of titanium alloy in the finite element software Third Wave AdvantEdge.The parameters of Ti6Al4V titanium alloy are established by the Power Law constitutive model.It′s verified that the parameters of the twist drill are within a reasonable range,Carbide-General carbide twist drill,different back angle,spiral angle,transverse edge angle,and rounded radius of the cutting edge on the drilling performance of titanium alloy.Finite element analysis by titanium alloy drilling process.When drilling a titanium alloy material for a twist drill,a reasonable reference for the geometrical parameters of the drill bit provides a reference basis to improve the quality of the drill.
