摘要
利用DEFORM-3D有限元软件对整体CBN刀具车削钛合金进行了三维仿真,采用单因素试验法模拟分析CBN刀具车削钛合金时切削速度、背吃刀量和进给量对切削力和切削温度的影响。仿真结果表明:对切削力影响最大的是背吃刀量,其次是进给量,切削速度的影响最弱。切削温度方面,切削速度对其影响最大,背吃刀量最小。
A three - dimensional finite element model of the titanium alloy turning with entire CBN was established by DEFORM - 3D software. The influence of cutting speed,cutting depth and feed rate on cutting force and cutting tempera- ture was simulated by single factor experiment. Simulated results show that： in all factors, the cutting depth with maximal impact on the cutting force, the feed rate is second, cutting speed on cutting force the minimum. On the contrary, the cut- ting speed with the greatest impact on the cutting temperature and cutting depth on cutting temperature minimum.
