| 摘 要： | 在GH4169镍基高温合金加工过程中，会产生严重的加工硬化现象以及因切削力过大等原因导致的难加工问题。利用ABAQUS软件建立二维正交车削有限元模型，分析GH4169超声椭圆振动车削的切削速度和振幅对切削力的影响，以及其刀具轨迹的变化情况，并与普通车削过程进行了对比分析。结果表明，在超声椭圆振动车削镍基高温合金中，切削工艺参数对切削力影响显著，选择合理的工艺参数可以有效地降低切削力，改善加工质量。

| Abstract: | In the process of processing GH4169 nickel?based superalloy, serious work hardening would occur, as well as difficult machining problems caused by excessive cutting force. The finite element model of two?dimensional orthogonal turning was established by ABAQUS software. The influence of cutting speed and amplitude on cutting force and the change of tool path of GH4169 ultrasonic elliptical vibration turning were analyzed. The results were compared with those of ordinary turning process. The results show that the cutting process parameters in the ultrasonic elliptical vibration turning of nickel?based superalloys have a significant effect on the cutting force. Choosing reasonable process parameters can effectively reduce the cutting force and improve the machining quality. |
