摘要
汽雾冷却切削技术可以减少切削过程中的切削力,改善材料的切削性能,提高刀具的使用寿命。文中建立了汽雾冷却下切削GH4169有限元仿真模型,在仿真模型中分析切削力随切削参数变化的规律。其次,在汽雾冷却条件下,使用陶瓷刀片车削GH4169。对比分析仿真数据与试验结果,验证换热系数可提高仿真分析的准确性,为汽雾冷却下高效切削GH4169切削参数的优选及仿真分析提供依据。
The spray-cooling cutting technology can reduce the cutting force in the cutting process,improve the cutting performance of materials,and lengthen the service life of cutting tools.In this article,the finite-element simulation model of cutting GH4169 with spray cooling is worked out,in which the changing law of the cutting force with various parameters is analyzed.In addition,under the working condition of spray cooling,GH4169 is turned by the ceramic blade.By comparing the simulation data with the experimental results,it’s verified the heat-transfer coefficient ensures a higher standard of accuracy in simulation,which has provided basis for optimization and simulation of cutting parameters of efficient turning GH4169 with spray cooling.
