Application of Orthogonal Experiment Method in Tool Geometry Parameter Optimization

  • 摘要: 首先,基于AdvantEdge金属切削有限元仿真软件建立三维铣削模型并设计三水平四因素正交试验方案,采用K系列硬质合金整体圆柱立铣刀对钛合金材料Ti6Al4V进行铣削仿真加工,得到不同刀具几何参数在设定加工条件下的接触面应力时间历程曲线。然后,利用综合平衡法,分析刀具几何参数在多因素条件下对铣削力和刀具切削温度的主次影响,初步选定最优铣削方案。最后,采用方差分析法对最优方案进行验证,并逐一分析刀具各因素在单一变化条件下对铣削力和刀具切削温度的影响。

     

    Abstract: In this paper, a three-dimensional milling model is built based on the AdvantEdge metal cutting finite element simulation software. Through designing a three-level four-factor orthogonal experiment scheme, milling simulation machining for the titanium alloy material Ti6Al4V is conducted by using K series cemented carbide overall cylindrical milling cutter; and the contact surface stress time course curves of different tool geometry parameters under set machining conditions are obtained. By means of the comprehensive equilibrium method, the primary and secondary influence of tool geometry parameters on milling force and tool cutting temperature under multi-factor conditions is analyzed, and the optimal milling scheme is initially selected. Finally, the optimal scheme is verified by the method of variance analysis, and the effect of tool factors on the milling force and cutting temperature under a single change is analyzed respectively.
