精密切削1Cr17Ni2不锈钢仿真分析

Precision Cutting Simulation Analysis of 1Cr17Ni2 Stainless Steel

由于1Cr17Ni2不锈钢强度高、硬度大,在切削过程中会产生较高的切削温度及切削力,从而影响工件的变形及表面质量。文中从实际加工角度出发,通过AdvantEdge-FEM软件建立切削仿真模型,研究精密车削1Cr17Ni2不锈钢时切削速度、切削深度对切削力和切削温度的影响规律。结果表明:切削深度对切削力影响较大,切削速度对其影响不明显;切削速度增大时,刀尖温度峰值近乎呈线性增大,随着切削深度的增加,刀尖温度峰值亦增大,但逐渐变缓。

Due to the high strength and hardness of 1Cr17Ni2 stainless steel,high cutting temperature and cutting force will be produced in the cutting process,which affects the deformation and surface quality of the workpiece.Based on the actual machining,this paper establishes the cutting simulation model using AdvantEdge-FEM software to study the influence law of cutting speed and cutting depth on cutting force and cutting temperature when precision turning 1Cr17Ni2 stainless steel.The results show that the cutting depth has a great influence on the cutting force,while the cutting speed has no obvious influence on it.When the cutting speed increases,the peak temperature of the tool tip increases linearly,and with the increase of the cutting depth,the peak temperature of the tool tip also increases but gradually becomes slow.
