| 中文摘要: |
| 针对淬硬H13热作模具钢在高速切削时的刀具耐磨性问题，选用了陶瓷铣刀和带涂层的3种硬质合金钢铣刀对其进行高速铣
削实验。首先，分析了在相同切削参数条件下不同刀具后刀面磨损量VB的变化情况；其次，分析了失效刀具的磨损机理；最后，探讨了刀具磨损量对零件
加工表面粗糙度的影响。研究结果表明：AlTiN涂层立铣刀刀具的耐磨性能最佳；刀具的磨损机理主要为磨粒磨损和粘结磨损，刀具的崩刃是硬质合金刀具的主要
失效形式；TiAlN涂层立铣刀对工件的表面形成的粗糙度变化趋势较为平稳，工件表面质量较好。 |

| To investigate the wear resistance of hardened H13 hot work tool steel in high speed cutting, ceramic milling cutter and three kinds of coated carbide
tools were used for high speed milling experiments. Firstly, the change of different tool flank wear VB was analyzed under the same cutting parameters. Secondly, the wear
mechanism of the failed tool was analyzed. Finally, the influence of tool wear on the surface roughness of the workpiece was discussed. The results showed that the wear resistance of AlTiN
coated carbide tool is the best; the wear mechanism of the tool is mainly abrasive and adhesive wear, the chipping of the tool is the main failure mode of the carbide tool; the TiAlN coated
carbide tool has a stable trend in the roughness of the workpiece surface and a better surface quality. |
