| 中文摘要: |
| 钛合金因其优异的高温热稳定性与高比强度，在高端装备制造业关键零部件中具有迫切的升级应用需求。然而，其极易发生高温切屑粘附且切削热不易散失的物理特性，常导致刀具快速失效，属于典型的难加工材料。针对钛合金的高效切削难题，本研究开发了一款基于不等分与不等螺旋角协同设计的钛合金专用整体硬质合金立铣刀。通过对立铣刀几何参数（优选双后角结构）、刃口机械钝化工艺以及高红硬性涂层材料的系统优化，显著改善了切削区的摩擦学环境。现场切削试验表明，与市售同类商用刀具相比，优化后的双后角立铣刀抗粘结磨损性能大幅提升，其累计稳定切削长度超过168 m，刀具实际使用寿命延长了～33.3%，显著提高了钛合金关键零部件的加工效率与表面完整性。 |

| The properties of titanium alloy materials meet the needs of some high-end manufacturing industries for performance upgrades in key components, such as high temperature resistance, thermal stability, and strength. However, the poor machinability of titanium alloy has long classified it as a difficult-to-machine material. During the titanium alloy cutting process, problems like chip adhesion to the tool and excessively high cutting temperature arise, posing numerous challenges to mechanical processing. Through the team's long-term research and development, an optimized solution with unequal division and unequal helix angles was developed. By continuously optimizing the parameter design of the end mill, the edge treatment process of the end mill, and the selection of coating materials, an integral cemented carbide end mill specifically designed for titanium alloy cutting was successfully created, solving the problems encountered in the titanium alloy cutting process. Cutting tests show that compared with tools produced by other companies, The cumulative cutting length of the double relief angle end mill exceeds 168 meters. The tool life can be extended by nearly one-third, and the processing efficiency is significantly improved. |
