摘要
刀具磨损过快是镍基高温合金GH4169在切削过程中一直存在的难题,因而刀具磨损特性的研究对工艺优化具有重要意义。通过Deform软件建立了具有槽型特征刀具的仿真模型,揭示了后刀面磨损量对切削过程的影响,并通过车削试验验证了仿真模型的准确性,获得了不同后刀面磨损量对切削力及切削温度的影响规律,同时也获得了该切削过程刀具的磨钝标准,对镍基高温合金精加工过程中的工艺优化具有较好的理论指导意义。
Too fast tool wear is a difficult problem in the cutting process of Ni-based superalloy GH4169,so it is of great significance to study the tool wear characteristics.The simulation model of groove characteristic tool is established by DEFORM software.The influence of the wear on the cutting process is revealed.The accuracy of the simulation model is verified by turning experiment,and the influence of different flank wear on cutting force and cutting temperature is obtained.At the same time,the blunt standard of cemented carbide cutting tools is also obtained.The analysis results have good guiding significance for process optimization during finishing process of Nibased superalloy.
