摘要
为了研究不同切削参数对铝合金切削过程中切削力和切削温度的影响,以铝合金7075-T651为对象,采用仿真与实验验证结合的方法,利用金属有限元切削专用软件AdvantEdge建立了铝合金7075-T651的二维正交切削仿真模型,并进行合理的工件和刀具材料参数以及本构模型设置。通过仿真分析,研究了切削力和切削温度与进给速度以及切削深度的关系,并通过实验进行验证。仿真和实验结果表明:在一定范围内,随着进给速度和切削深度的增大,切削力和切削温度增大。切削铝合金7075-T651时,应采用较小的切削深度和进给速度。
In order to study the influence of different cutting parameters on cutting force and cutting temperature in cutting process of aluminum alloy,this research uses aluminum alloy 7075-T651 as the object,and takes the method of combining simulation and experimental verification as the research method.This paper proposes to use special software AdvantEdge of metal finite element cutting to establish two-dimensional orthogonal cutting simulation model of aluminum alloy 7075-T651.Reasonable workpieces,tool material parameters and constitutive model are set.Through simulation analysis,the relationship between cutting force and cutting temperature,feed speed and depth of cut are studied and verified by experiments.Simulation and experimental results show that within a certain range,with the increase of feed speed and cutting depth,cutting force and cutting temperature increase.When cutting aluminum alloy 7075-T651,smaller depth of cutting and feed rate should be used.
