| 摘 要： | 钛合金Ti6Al4V因其优良的综合性能在航空航天领域有着广泛的应用。然而,在钛合金切削过程中,极易出现刀具磨损现象。目前尚缺乏钛合金加工用刀具寿命预测的有效手段和方法。针对这一问题,基于刀具在铣削工作过程中受到的热力耦合作用,利用Fick扩散定律揭示了刀具扩散磨损机理,构建刀具磨损模型;利用有限元仿真软件Advant Edge的二次开发技术,将刀具磨损模型嵌入到有限元模型中,进行刀具磨损的预测;进而借助刀具寿命试验,验证了刀具磨损模型的可靠性。 |

| Abstract: | Titanium alloy Ti6Al4V is widely used in aircraft industry applicationsdue to excellent performance.However, tool wear is a prominent problem. There is a lack of effective method of tool life prediction for titanium alloy processing. The thermal-mechanical coupling effect for carbide tool wear is discussed and the tool wear model is proposed based on Fick diffusion laws. Finally, the validity of the model is verified by comparing the simulation results obtained from the secondary development AdvantEdge simulation software with the experimental results. |
| Keywords: | milling Ti6Al4V tool wear wear model finite element |
