【摘要】：針對300M超高強度鋼切削加工性較差的問題,通過有限元仿真技術對300M鋼的高速切削過程進行研究。在相關試驗數(shù)據(jù)的基礎上,創(chuàng)建高速切削仿真模型,研究切削過程中切屑形態(tài)、切削區(qū)的應力分布,以及切削速度、刀具幾何角度的變化對切削力、切削溫度的影響規(guī)律。仿真結果分析表明:仿真數(shù)據(jù)與試驗數(shù)據(jù)的變化趨勢基本相同,切削速度增大,切削溫度隨之升高,切削力先升高后下降;前角角度增大,切削力和切削溫度都較大程度下降,應力向刀尖與工件接觸區(qū)集中;后角增大,切削力和切削溫度略有下降,但變化幅度較小。
[Abstract]:In view of the poor machinability of 300m ultra-high strength steel, the high-speed cutting process of 300m steel is studied by finite element simulation technology. Based on the relevant experimental data, a high-speed cutting simulation model is established to study the influence of chip shape, stress distribution in cutting zone, cutting speed and tool geometry angle on cutting force and cutting temperature. The simulation results show that the trend of the simulation data is the same as that of the test data. The cutting speed increases, the cutting temperature increases, and the cutting force increases first and then decreases. With the increase of the angle of the front angle, the cutting force and the cutting temperature decrease greatly, and the stress is concentrated in the contact region between the tool tip and the workpiece, while the back angle increases, the cutting force and the cutting temperature decrease slightly, but the range of change is small.
