摘要:
利用AdvantEdge切削仿真软件建立二维直角切削过程的数值仿真模型,通过改变工件材料本构模型中的初始应力、应变硬化系数、应变率强化系数和热软化系数,获取各模型参数对二维直角切削仿真结果的影响. 结果表明:对切削力、刀尖温度和应力影响最大的是热软化系数,对切屑形貌影响最大的是初始应力;材料本构模型主导切削仿真过程中的应力-温度场耦合过程,同时,本构模型参数对仿真结果的影响具有明显的非线性效应.
Abstract:
2D orthogonal cutting simulation model has been built by commercial FEM code AdvantEdge. The influence of the governing parameters on the simulation results of 2D orthogonal cutting has been achieved by modifying the governing parameters of material constitutive mode, which includes the governing parameters of initial stress, strain hardening, strain rate hardening and thermal softening. It is found that the effect of governing parameter of thermal softening on cutting forces, cutting temperature and tool stress is maximal, comparing the other governing parameters. The effect of governing parameter of initial stress on chip morphology is maximal, comparing the other governing parameters. Material constitutive model dominates the thermal-mechanical coupling process in cutting simulation. The effects of constitutive model parameters on the simulated results show obvious nonlinear characteristics.
