摘要
以TC4钛合金的Johnson-Cook本构模型和切削磨损模型为依据,用数值模拟软件对TC4切削过程毛刺的形成进行仿真模拟,通过控制单一变量的方法,分别改变切削深度、进给速度、切削速度及切削温度等工艺控制参数,模拟了毛刺的产生、长大及断裂等过程,通过比较分析,得到了同一条件下毛刺尺寸与切削工艺参数之间的关系。最终通过合理选择切削工艺参数,有效控制毛刺的形成,提高被加工制件的表面质量和生产效率。
Based on TC4 titanium alloy Johnson-Cook numerical software package was applied to simulate the formation simulation in different cutting depths, feeding constitutive model and the cutting wear model, burr formation of TC4 cutting process. The burr rates, cutting speeds and cutting temperatures was conducted by controlling the single variable method. The relations between cutting parameters and geometric dimensioning for new developed burrs were obtained in the same turning condition. Finally, the appropriate cutting parameters were determined to effectively control the deformation of burr, so as to improve surface quality and production efficiency of the forming parts.
