摘　　要：为了研究不同的冷却方式对车削45钢的结果影响,利用专用的金属切削有限元分析软件AdvantEdge模拟二维车削加工过程。在仿真切屑的形成过程中,分析了常规冷却和高压冷却车削方式下对刀具的温度、应力以及形成的切屑大小的影响。仿真结果表明:采用高压冷却车削可以降低刀具切削刃的温度、等效应力和最大剪应力,不仅能够快速冷却,而且可以减少刀具的磨损;高压冷却车削还可使切屑易于折断,从而改善切屑的长度,有效的避免了加工过程中的缠屑现象。In order to study the impact of the results of turning 45 steel in different cooling methods, The two-dimensional turning process is simulated with AdvantEdge, which is a special finite element analysis software for metal cutting, In the simulation of the chip formation, analysis the impact of tool temperature, stress and chip size in the conventional cooling and high pressure cooling turning mode. Shown the simulation results ,the use of high-pressure cooling can reduce the temperature, equivalent stress and maximum shear stress of cutting edge of the tool, not only to rapid tool cooling, but also reduce tool wear; High-pressure cooling turning can also make the chip easily broken, thus improving chip length, effectively avoid the phe- nomenon of the chip winding in the process.
