摘要
以汽车钛合金连杆为研究对象,分析了钛合金连杆在切削加工工艺过程中的刀具磨损量、切削力和刀具寿命随着切削速度、润滑压力的变化规律。试验分析结果表明:刀具磨损量随着切削速度的增加而增加,随着水射流润滑压力的增加先减小后增加;刀具切削力和轴向力均随着水射流压力的增大先减小后增加,但轴向力的变化较切削力更加敏感,变化速率更快;刀具寿命随着切削速度的增加而减小,随着水射流压力的增加先增大后减小,钛合金连杆的最佳工况为切削速度75m/min,润滑压力10MPa。
The automobile titanium alloy connecting rod was regarded as the study object ;the effects different cutting speeds and lubrication pressures to the tool wear, cutting forces and tool life of titanium alloy connecting rod were re- searched. The experimental results show that with the increase of cutting speed, the tool wear increases;with the increase of the pressure of the jet water, the tool wear first increases and then decreases ; the cutting force and the axial force of the cut- ting tool first decreases and then increases with the increase of the pressure of the jet water, but the change rate of axial force is more sensitive to the cutting force;the tool life decreases with the increase of the cutting speed and increases with the increase of the pressure of the jet water,the best work conditions of titanium alloy connecting rod can get at the cutting speed of 75m/min and the lubrication pressure of 10MPa. The experiments prove that the jet water assisted lubrication can increase the tool life and improve the surface properties of the materials, which provides a theoretical basis for titanium ma- terials and automotive components manufacturing.
