摘要
为了研究镍基高温合金加工中切削用量对切削力的影响,课题组借助高温合金的材料本构模型、失效准则、切削过程中的切屑分离准则和摩擦模型,利用ABAQUS有限元分析软件建立了镍基高温合金的二维切削仿真模型,分别以切削速度、切削深度和进给量为单一变量,探究切削力的变化规律。结果表明:切削力随切削速度的增加而减小,并趋于稳定状态;切削力随着进给量和切削深度的增大而增大;相较于切削速度,进给量和切削深度对切削力的影响更大。
In order to study the effect of cutting parameter of nickel-based superalloy on cutting force,a two-dimensional cutting simulation model of nickel-base superalloy was established by finite element analysis software ABAQUS,with the help of the constitutive model of the superalloy,the failure criterion,the chip separation criterion and the friction model during the cutting process.. The effect of cutting speed,cutting depth and feed rate on cutting force were investigated.The result show that cutting force decreases with increasing cutting speed and tends to be stable;On the contrary,cutting force increases with increasing cutting feed and cutting depth. In general,the influence of cutting feed and cutting depth on cutting force is greater than cutting speed.
